1.5 SA70R–AK Enclosure Overview
The SA70R–AK enclosure provides power, control, and cooling for up to four RA7x–RK removable
disk drives. Figure 1–3 shows an exploded view of the SA70R–AK enclosure. The major
subassemblies of the SA70R–AK enclosures are as follows:
•

Chassis

•

Operator control panel (OCP)

•

Transition board assemblies (TB1–M and TB2)

•

Power supply

•

Fan assemblies (two)

•

Cable harness

•

Canister lock/release mechanisms (four)

•

Canister ready indicators (four)

•

RA7x–RK removable disk drives (up to four)

•

SDI cables

Each RA7x–RK removable disk drive fits into one of four recessed positions in the front of the
enclosure. The canister is secured in the enclosure by the canister lock/release mechanism. The
OCP is mounted on the front of the enclosure above the canisters and plugs into the internal
transition board assembly #1 (TB1–M). TB1–M connects the OCP to transition board assembly
#2 (TB2). TB2 sits internally above the canisters and transfers drive signals to the OCP through
TB1–M. The power supply and fan assemblies are mounted in the rear of the enclosure behind the
canisters. A cable harness containing interconnecting cables and internal SDI cables runs through
the enclosure chassis.
NOTE
The TB1–M used in the SA70R–AK enclosure is not interchangeable with the TB1 used in
the SA7x enclosure. The boards are of different designs and operate correctly only when
installed in the appropriate enclosure.

The enclosure power supply provides operating power to the major subassemblies of the enclosure.
The power switch for the enclosure is located on the rear panel of the enclosure.
Each RA7x–RK removable disk drive is powered and controlled independently. You can operate a
disk drive with other disk drive positions unoccupied or while maintenance is being performed on
another drive. The power switch for each disk drive is activated automatically (by a microswitch
in the canister lock/release mechanism on the enclosure) when you insert the canister into the
enclosure. The power switch is deactivated when you move the lock/release handle to the right
to remove the canister. Next to each canister lock/release handle on the front of the enclosure
is a canister ready indicator that lights when the RA7x–RK removable disk drive is powered up
and ready for operation. Indicator symbols show which set of switches and indicators on the OCP
correspond to that particular drive position.

Digital Internal Use Only

Introducing the SAx05 Storage Arrays 1–7

The RA7x–RK removable disk drives are operated from four sets of switches and indicators on the
OCP. Each control set operates one disk drive in the enclosure.
Two fan assemblies circulate cooling air throughout the interior of the SA70R–AK enclosure.
The air is drawn into the enclosure through the front and is exhausted at the rear. The fans
operate at two speeds. When the temperature exceeds 29°C (85°F) the fans operate at high speed;
otherwise, they operate at normal speed. Also, if one fan is not operating, the other fan accelerates
to high-speed.
Additional information about the SA70R–AK enclosure subassemblies can be found in
<REFERENCE>(desc_chap).

1.6 RA7x–RK Removable Disk Drives Overview
The RA7x–RK family of removable disk drives includes the RA70–RK, RA71–RK, and RA72–RK.
The RA7x–RK disk drives are designed for the SAx05 storage arrays. They can be installed into
and removed from the SA70R–AK enclosure on a regular basis. Once removed from the enclosure,
these disk drives can be stored or transported. A canister carrying case (part number RA70X–AK)
is available for transporting a disk drive off site.
The RA7x–RK disk drive consists of an RA70, RA71, or RA72 disk drive mounted in a metal
canister. The disk drive canister features modular components that can be replaced with minimum
downtime.

2. Unpack the two filler panels.
3. Remove and save the four 10-32 x 1/2-inch screws (two on each side) and the two wing nuts
from each filler panel.
4. Install the filler panels by connecting them to the top and bottom spreaders, as follows:
NOTE
One filler panel has two rectangular openings; the other panel is solid. If cables will
exit at the bottom of the cabinet and be routed under a false floor in the computer
room, install the filler panel with the rectangular openings at the bottom of the
cabinet, and the solid panel at the top. If cables will exit at the top of the cabinet
and be routed through the computer room ceiling, install the filler panel with the
rectangular openings at the top of the cabinet and the solid panel at the bottom.
a. Place the appropriate filler panel on top of the top spreader.
b. Push the two captive studs on the filler panel through the two slots in the spreader.
c.

Move the filler panel toward you until the captive studs stop at the ends of the slots.

d. Install and tighten the two wing nuts on the captive studs.
e.

Repeat this procedure to connect the bottom filler panel to the spreader.

5. Loosen the three 1/4-20 x 3/4-inch screws located on the top, middle, and bottom of each side
panel.
6. Pull the side panels toward you until the U-shaped screw holes at the top and bottom of the
side panels line up with the screw holes on the sides of the filler panels.
7. Reinstall the eight 10-32 x 1/2-inch screws (four from each filler panel) to secure the side panels.
Insert two at the top and two at the bottom of each side panel and tighten.
8. Determine how far the cabinet rear access panel will need to be extended. This decision
depends on the number of enclosures and drives installed in the cabinet:
•

If the cabinet is fully populated, the rear access panel must be fully extended to
accommodate the cables.

•

If only a few enclosures and drives are installed, the rear access panel can be partially
extended.

To use a fully extended rear access assembly, leave the assembly fully extended and tighten the
three 1/4-20 x 3/4-inch screws on each of the two side panels.
To use a partially extended rear access assembly, perform the following procedure:
a. Loosen the two wing nuts on each filler panel.
b. Gently push the rear access panel back into the cabinet until you encounter resistance.
c.

Retighten the wing nuts.

d. Tighten the three 1/4-20 x 3/4-inch screws on each of the two side panels.

2.6 Affixing Operator Control Panel Labels
SAx05 storage arrays are shipped with English labels on the operator control panel (OCP).
However, a packet of self-adhesive labels in several languages is included in the shipping package.
If necessary, select the appropriate label from the packet and affix it to the OCP on top of the
English label.

2.7 Connecting External SDI Cables
SDI (Standard Disk Interconnect) cables include external cables, internal cabinet cables, and
internal enclosure cables. All internal cabinet SDI cables and power cords are factory-installed
for preconfigured SA70R–AK enclosures. You will not need to install these cables unless you are
installing an add-on enclosure. Refer to Chapter 5 for information about installing add-ons.
Figure 2–6 shows the configurations for connecting the external SDI cables to the SA705 I/O
bulkhead. Figure 2–7 shows the configurations for connecting the external SDI cables to the SA905
I/O bulkheads. Secure all external cables to the I/O bulkhead with the connector retaining screws.

2.8 Selecting Line Input Voltage to the SA70R–AK Enclosure
The SA70R–AK enclosure power supply can be set to operate from either 120 Vac at 60 Hz or
220/240 Vac at 50 Hz. The power supply is set to 240 Vac (50 Hz) at the factory and must be reset
to 120 Vac (60 Hz) for some installations. The line input voltage setting on the enclosure must be
the same as the voltage rating for the 881 power controller in the SAx05 cabinet. The 881–A power
controller is rated at 120 Vac; the 881–B power controller is rated at 240 Vac.
CAUTION
If the voltage selector switch on the SA70R–AK enclosure is set to 120 Vac (60 Hz) and 240
Vac (50 Hz) is used, severe damage to the power supply will occur at power up.
Use the following procedure to select the proper line input voltage for the SA70R–AK enclosure:
1. Verify that the power switch on the rear panel of the enclosure is off (0).
2. Locate the line voltage selector switch through the rear panel of the enclosure. See Figure 2–8
for the location of the line voltage selector switch.
3. Verify that the line voltage selector switch is set at the same voltage rating as the 881 power
controller (120 Vac for the 881–A power controller; 240 Vac for the 881–B power controller). If
the setting is incorrect, use a small screwdriver to change the setting.

•

The top symbol corresponds to the Bus position of the switch and is used for remote
operation of the controller. If you are using this mode of operation, refer to the 881 Power
Controller User Guide for instructions.

•

The center symbol indicates the off position of the Bus/Off/On switch.

•

The lower symbol indicates the on position of the Bus/Off/On switch.

NOTE
Apply techniques learned in the Electrical Safety and Lockout/Tagout Procedures
course prior to performing the next step.
4. Plug the 881 power cord into a correct external power source.
5. Raise the circuit breaker handle at the rear of the 881 power controller to the on (1) position to
apply power to the cabinet.
6. Turn the power switch on the rear panel of each enclosure on (1) to apply power to the
enclosures.
7. Perform the post-installation checkout procedure. (Refer to Section 2.10 for instructions.)

2.10 Performing the Post-Installation Checkout Procedure
The post-installation checkout procedure enables you to verify functionality of the power supply, fan
assemblies, and OCP for each enclosure, before you begin operation.
After applying power to the SAx05 enclosure, perform the post-installation checkout procedure as
follows:
1. Verify power supply operation by making sure all enclosure fans are operating. Do this by
checking for airflow out of the rear of each enclosure. If the fans are not operating:
a. Verify that all power and interface connections on the rear of the enclosure are correct and
secure.
b. Verify that the power supply is firmly seated in its connector.
NOTE
If one of the fans is not operating, the two disk drives situated in front of that fan
will not operate.
2. Check to see if any of the fault indicators on any of the enclosure rear panels are lit. If a fault
indicator is lit:
a. Turn off power to that enclosure for 10 seconds, then turn the enclosure back on.
b. If the fault indicator lights again, refer to Chapter 6 and contact your Digital Customer
Services engineer.
3. Verify power application to each occupied disk drive position by checking the canister ready
indicator lights. If a canister ready indicator is not lit, verify that the disk drive is correctly
inserted in the enclosure. (Refer to Section 4.5.)

Digital Internal Use Only

Unpacking and Installing the SAx05 Storage Arrays 2–17

Applying power to the disk drive starts the drive’s internal power-on diagnostics. These
diagnostics are signaled at the OCP by the following sequence of indicator lights:
a. All indicators light for about 8 seconds.
b. If the drive completes the power-on diagnostics without detecting a fault, all indicators go
out.
c.

If the Fault/Set No. indicator remains lit, the drive has detected a fault. Press the Fault/Set
No. switch twice to clear the fault. If the indicator remains lit, refer to Chapter 6 for fault
recovery procedures.

4. Perform an OCP lamp test to ensure the LED state indicators are working properly. Do this
by pressing and holding the Fault/Set No. switch for each occupied drive position; all lamps
should momentarily light. If lamps do not light, ensure the OCP is seated properly and power
is applied to that disk drive, then try the test again.
5. Set the drive unit number for each disk drive in the storage array. (Refer to Section 2.11.)

2.11 Setting the Drive Unit Numbers During Installation
The drive unit number is the number the system uses to identify the drive. This number is
automatically read by the drive at power up and after the number has been reset. You can set
the drive unit number for any disk drive at the OCP. Once the number is in the drive, the system
controller reads it according to the controller’s protocol.
Refer to Section 3.8 for additional information about setting drive unit numbers during routine
operation.
Use the following procedure to set the drive unit number during an initial installation (see
Figure 2–11):
CAUTION
Be sure that no two disk drives in your system have the same drive unit number. Using
the same drive unit number for two disk drives causes a controller fault and results in
both drives spinning down.
1. Locate the Unit Select switch in the upper right corner of the OCP. Carefully press the Unit
Select switch with a pointed object such as a pen or small screwdriver. The unit select numbers
for all powered-on drives in the enclosure flash to indicate that the OCP is in unit select mode.
2. Press the Fault/Set No. switch for the selected drive once to increment the unit number by one.
Press and hold the Fault/Set No. switch to rapidly increment the unit number. Set the unit
number to any number between 000 and 255.
NOTE
You cannot decrement a drive number. Continue holding the Fault/Set No. switch
until it increments to 255; it then restarts at 0.
Repeat this step for each disk drive in all enclosures.
3. When you finish setting the unit numbers, restore the OCP to normal operation by pressing the
Unit Select switch again.
Refer to Chapter 3 for a detailed description of the OCP switches and indicators, and instructions
for bringing the disk drives on line.

The OCP contains a Unit Select switch and four identical sets of switches and indicators, one
control set for each disk drive position in the enclosure. (See Figure 3–4.) Table 3–1 summarizes
the functions of the SA70R–AK enclosure front panel switches and indicators during normal
operation. Each control set is made up of the following switches and indicators:
NOTE
All OCP switches except the Fault/Set No. switch are set when depressed. These switches
remain set until you release them by pressing them again. An indicator lights in each
switch to show the status of the drive function.

Digital Internal Use Only

3–8 Operating the SAx05 Storage Arrays

The Fault/Set No. switch is a momentary push button. When you press the switch and
hold it, it is set; when you release the switch, it is reset.
•

Run—Pressing the Run switch causes the drive to spin up. The yellow Run indicator lights
after the drive spindle reaches operating speed. Pressing the Run switch again releases the
switch and causes the drive to spin down. The yellow Run indicator goes out only after the
drive spindle comes to a complete stop.

•

Fault/Set No.—Pressing and holding the Fault/Set No. switch during normal operation causes
all OCP indicators to light as a lamp test. When a fault condition is detected in a disk drive,
the red Fault/Set No. indicator lights. Pressing the Fault/Set No. switch once after a drive
fault takes the drive off line and causes all indicators in the drive’s control set, including the
Fault/Set No. indicator, to blink an error condition code. Pressing the Fault/Set No. switch a
second time clears the error code and commands the drive to attempt to clear the error and
return on line. The Fault/Set No. switch is also used to set the drive unit number, as described
in Section 3.8.

•

Ready—The green Ready indicator lights to show that the drive is ready for read/write
operations. This indicator is activated only after the Run switch is set and the yellow Run
indicator is lit. The Ready indicator remains on during normal operations but may blink or
go out during heavy disk usage. During spinup, the drive performs diagnostics and servo
calibrations. The Ready indicator must light within 60 seconds after you press the Run switch;
failure to do so indicates a problem in the drive.

•

Unit No.—The unit number for the disk drive is displayed next to the Ready indicator. The
unit number can be set to any number between 000 and 255, as described in Section 3.8.
Placement of unit numbers in an actual installation is shown in Figure 3–4 (unit numbers 000
through 003 in this example).

•

Write Protect—Setting the Write Protect switch disables writing to the drive. This function
keeps the drive data from being overwritten and lost. The yellow Write Protect indicator lights
to show that a drive is write protected. The drive may also be write protected by a system
controller command; this also causes the Write Protect indicator to light.

•

A and B—You enable ports A and B using the port A and port B select switches. Yellow
indicators in each switch light to show that the system controller has selected the port.

The Ready and Run indicators remain lit during normal operation, although the Ready indicator
may flicker during heavy seek activity. The Write Protect indicator is on if the drive is write
protected and off if the drive is write enabled. The port A and B indicators light only while their
respective ports are selected by the system controller.

3.4.2 Canister Ready Indicators
A canister ready indicator is located above each of the disk drive positions on the front of the
SA70R–AK enclosure. Four conditions are necessary for the indicator to light:
•

AC power must be available to the SA70R–AK enclosure.

•

The SA70R–AK enclosure power switch must be on.

•

The RA7x–RK removable disk drive must be properly inserted in the enclosure.

•

Power must be enabled to the disk drive through the microswitch in the canister lock/release
mechanism.

•

The power supply must be supplying the correct voltage to the disk drive.

The symbol on each canister ready indicator corresponds to the related set of switches and
indicators on the OCP.

Operating the SAx05 Storage Arrays 3–9

Inserting an RA7x–RK removable disk drive automatically connects power to that disk drive and
causes the drive to run a power-up self test. All OCP indicators light for a few seconds, then go
off to indicate a successful test. After inserting the canister, you must press the Run switch on
the OCP to spin up the drive. Refer to Chapter 4 for RA7x–RK removable disk drive insertion and
removal procedures.

3.5 SA70R–AK Rear Panel Switches and Indicator

Line voltage selector switch—As you face the rear panel of the enclosure, the line voltage
selector switch is located to the right of the power switch. It is visible through a hole in the rear
panel. Your Digital Customer Services engineer sets this switch to the available line voltage
during installation. The selected voltage is shown on the switch element. Section 5.8 describes
the procedure for selecting the proper line voltage when installing an add-on SA70R–AK
enclosure.
CAUTION
The SA70R–AK enclosure power supply is universal for both 120 Vac at 60 Hz or 240
Vac at 50 Hz. The supply is factory set to 240 Vac at 50 Hz and must be reset to 120
Vac at 60 Hz for some installations. Selecting the wrong voltage will damage the
supply.

•

Fault indicator—A red fault indicator is visible, when lit, through holes in the upper
right-hand corner of the power supply. When the power supply detects an overtemperature
or overvoltage condition, it automatically shuts down power to the enclosure and the fault
indicator lights. If the fault indicator lights, turn off the enclosure for 10 seconds, then turn the
enclosure back on. If the fault indicator lights again, call Digital Customer Services.

3.6 Bringing a Disk Drive On Line
To bring a disk drive on line, perform the following procedure:
NOTE
This procedure assumes the disk drive has already been environmentally stabilized and
inserted into the enclosure. While the disk drive is automatically powered up upon
insertion, it does not spin up.
If the disk drive is not already in the enclosure, refer to Chapter 4 for instructions on
inserting the RA7x–RK removable disk drive into the SA70R–AK enclosure.
1. Spin up the selected drive by pressing the Run switch on the OCP control set for that drive.
(See Figure 3–4.) The following sequence of indicator lights occurs during spinup:
a. The Run indicator lights to show that you have commanded spinup. If you have inserted
the RA7x–RK removable disk drive with the Run switch set, you must either momentarily
release then reset the Run switch or issue a mount command from your system to initiate
spinup. The Run indicator lights to show that spinup was initiated through either of these
actions. All other indicators remain off.
b. When the drive completes spinup, the Ready indicator lights to show that the drive is
read/write ready. The Ready indicator then flashes while the internal read/write and
seek diagnostics run. Upon completion of the read/write and seek diagnostics, the Ready
indicator remains lit.
c.

2. Select port A, port B, and Write Protect, as required, by pressing the appropriate switches. To
deselect these functions, press the switches a second time.

3.7 Taking a Disk Drive Off Line
To take a disk drive off line, perform the following procedure:
1. Dismount the disk drive using the proper system commands.
2. Press and release the port A and port B switches on the OCP to deselect both ports of the disk
drive. Wait for the port indicators to go out. (See Figure 3–4 for the location of the port A and
B switches.)
If you intend to remove the disk drive from the enclosure, you must also spin the drive down as
follows:
3. Press and release the appropriate Run switch on the OCP. Wait for the Run indicator to go out.
4. Remove the RA7x–RK removable disk drive from the enclosure. (Refer to Section 4.5.) The
canister ready indicator goes out to indicate that power has been removed from that disk drive
position.

3.8 Setting the Drive Unit Number During Operation
The drive unit number is the number the system uses to identify the drive. This number is
automatically read by the drive at power up and after the number has been reset. You can set
the drive unit number for any disk drive at the OCP. Once the number is in the drive, the system
controller reads it according to the controller’s protocol.
NOTE
The drive unit number is stored on transition board #2 (TB2). The disk drive does
not maintain the unit number when the drive is moved to a different position in the
enclosure. However, the drive unit number is saved during a power failure by the
nonvolatile storage on TB2.
Use the following procedure to set the drive unit number for a selected drive during routine
operations:
CAUTION
Be sure that no two disk drives in your system have the same drive unit number. Using
the same drive unit number for two disk drives causes a controller fault and results in
both drives spinning down.
1. Dismount the selected disk drive and take it off line. (Refer to Section 3.7.)
NOTE
It is not necessary to take other drives in the same enclosure off line when setting a
drive unit number.
2. Locate the Unit Select switch in the upper right corner of the OCP. Carefully press the Unit
Select switch with a pointed object such as a pen or small screwdriver. The unit select numbers
for all powered-on drives in the enclosure flash to indicate that the OCP is in unit select mode.
When the OCP is in unit select mode, all drives not spun down continue to operate according to
the settings of the OCP switches.
3. Set the drive unit number to any number between 000 and 255, as follows:
CAUTION
Pressing the Fault/Set No. switch for a disk drive that is on line causes the drive to
go off line.
•

To increment the drive unit number by one, press the Fault/Set No. switch once.

5.6.2 Installing Internal Cabinet SDI Cables and a Power Cord in an SA905
Storage Array
Each SA70R–AK enclosure uses one power cord and two internal cabinet SDI cables—one for port A
and one for port B. Each SDI cable has a single connector at one end that connects to the enclosure,
and four connectors at the other end that connect to the vertical I/O bulkhead. The four connectors
are labeled for placement at the I/O bulkhead.
The H9A00 cabinet has two vertical I/O bulkheads, one on each side of the rear of the cabinet. The
I/O bulkhead on the left (facing the rear of the cabinet) is for port A connections; the I/O bulkhead
on the right is for port B connections. Each vertical I/O bulkhead has five sets of eight ports.
Figure 5–10 shows the configurations for SDI cables in a fully configured SA905 storage array. Use
the following procedure to install the two internal cabinet SDI cables (port A and port B) and power
cord for the newly installed SA70R–AK enclosure in an SA905 storage array:
1. If you have not done so already, remove the cabinet rear access panel. (Refer to Section 3.3.)
2. Connect the two SDI cable connectors to the rear of the enclosure—one at port A, one at port B.
(See Figure 5–10.) Secure each connector to the enclosure with the two retaining screws.
3. Connect each of the four smaller cables extending from the bottom of each SDI cable to the side
I/O bulkheads. (See Figure 5–10 for I/O bulkhead connections.)
4. Secure each connector to the I/O bulkhead with two retaining screws. The screws are packaged
in a separate bag.
5. Connect the power cord as follows:
a. Connect the power cord to the rear of the SA70R–AK enclosure.
b. Route the power cord down the left side of the cabinet (when facing the rear of the cabinet),
along the vertical I/O bulkhead.
c.

Connect the opposite end of the power cord to the appropriate connector on the 881 power
controller. (See Figure 5–10 for power cord connections.) Coil any excess power cord in front
of the power controller.

If the fault indicator is lit:
1. Immediately turn off (0) the power switch located on the rear of the enclosure and check for
airflow obstructions.
2. If you suspect the enclosure has been exposed to an overtemperature condition, allow the
enclosure to cool, then turn it back on. If the enclosure returns to normal operation (the fans
operate and the fault indicator does not light), an overtemperature condition is the likely cause
of the failure. Refer to Table 1–2 for recommended environmental limits and ensure that the
operating site complies with these limits.
If the enclosure has not been exposed to an overtemperature condition, leave the power switch
off for 10 seconds, then turn it back on (1).
a. If the fault indicator does not light, resume normal operation.
b. If the fault indicator lights, call your Customer Services engineer.

Digital Internal Use Only

Troubleshooting 6–3

If the red fault indicator is not lit:
1. Verify site power by checking other equipment on the same line and the circuit breakers to the
cabinet.
2. Verify that the enclosure power plug is connected to the line outlet in the cabinet.
3. Verify that the storage array’s power plug is connected to the site’s line voltage outlet.
4. Verify that the line voltage selector switch on the rear panel of the enclosure is set to the correct
voltage. (See Figure 6–1 for the location of the line voltage selector switch.)
5. Verify that the 881 power controller and the enclosure power supply are turned on.
6. Check for an overvoltage condition in the power supply by removing power to the disk drives.
Do this by releasing the lock/release handle (move the handle to the far right) for each disk
drive canister.
a. If the enclosure fans start, proceed to step 3 in Section 6.3.
b. If the enclosure fans do not start, contact your Customer Services engineer.

6.3 Troubleshooting Flashing Canister Ready Indicators
Flashing canister ready indicators indicate an overcurrent condition at the power supply output. If
the canister ready indicators on the front panel of the enclosure are flashing:
1. Reset the OCP switches as follows:
a. Deselect both ports A and B.
b. Press and release the Run switch for that disk drive. (See Figure 6–2.)
c.

Repeat this step for all drives in the enclosure.

2. Remove power to the disk drives by releasing the lock/release handle (move the handle to the
far right) for each disk drive.
3. Restore power to the disk drives by pushing them in one at a time.
a. If the canister ready indicator lights steadily when you insert a disk drive, that drive is not
causing the overload.
b. If the canister ready indicator flashes when you insert the disk drive, that disk drive is
probably causing the overload.
4. Insert the disk drive that caused the indicator to flash into a different opening in the enclosure.
a. If the indicator for that opening flashes, the disk drive is at fault. Remove the defective
disk drive and resume operation.
b. If the indicator for that opening does not flash, the opening that had the flashing indicator
is at fault. Call your Customer Services engineer.

6.4 Troubleshooting a Nonlighting Canister Ready Indicator
If a canister ready indicator does not light when you insert a disk drive:
1. Verify that the canister is fully seated in the enclosure and the lock/release handle has moved
completely to the left.
2. Verify that the canister ready indicators for other occupied disk drive positions are lit.
a. If the other canister ready indicators are not lit, verify power to the enclosure as explained
in Section 6.2.
b. If the other canister ready indicators are lit, insert another disk drive in the suspect
position.
•

If the canister ready indicator lights, the original disk drive is probably at fault. Do not
use the disk drive.

•

If the canister ready indicator does not light, the enclosure is probably at fault. Contact
your Customer Services engineer.

6.5 Troubleshooting Flashing Unit Number Indicators
If all the Unit Number indicators on the OCP are flashing, the panel has been placed in the unit
select mode. Carefully press the Unit Select switch with a pointed object or small screwdriver to
restore normal operation.

6.6 Troubleshooting a Noncommunicating Disk Drive
If a single disk drive is not communicating with the system controller or does not respond to OCP
commands (all other drives are normal):
1. Verify that the disk drive is properly inserted in the enclosure.
2. Verify that the appropriate port switch is selected.
3. Record any error code displayed on the OCP, as described in Section 6.8.
4. If the drive was previously on line:
a. Dismount the drive from the system, take the drive off line, and spin it down by pressing
the Run switch.
b. When the Run indicator goes out, remove power to the drive by fully releasing the
lock/release handle (move the handle to the far right). Removing power to the drive for
10 seconds resets the drive’s circuits.
c.

After 10 seconds, restore power to the drive by pushing the canister in fully.

5. Verify that the SDI cable connectors from the host system are securely tightened at the cabinet
I/O bulkhead.
6. Attempt to bring the disk drive back on line and restore normal operation.
7. If you still cannot bring the disk drive back on line, contact your Customer Services engineer.

6.7 Troubleshooting Noisy Fans
If the enclosure fans seem noisier than usual, they are probably operating at high speed. When the
temperature inside the enclosure exceeds 29 degrees C (91 degrees F), the fans automatically switch
to high speed operation. Refer to Table 1–2 for recommended environmental limits and verify that
your site complies with these limits.

Digital Internal Use Only

6–6 Troubleshooting

6.8 Recovering from a Drive Fault Condition
The RA7x–RK disk drive contains sophisticated circuits to detect and report fault conditions. These
faults are reported to you through an error code displayed on the OCP. Your Customer Services
engineer uses these codes and other error reporting mechanisms in the disk drive to pinpoint the
source of a fault and return your disk drive to service in a minimal amount of time.
If the Fault/Set No. indicator lights to signal that the disk drive has detected a fault, use the
following procedure (see Figure 6–2):
1. Press the Fault/Set No. switch once to display an error code on the OCP. The error code is
displayed as flashing indicators.
2. Record which indicators are flashing. Your Customer Services engineer will use this code to
isolate the cause of the drive fault.
NOTE
While in the fault mode, the OCP indicators do not retain their normal function; they
act only as error code indicators until you press the Fault/Set No. a second time.
3. Press the Fault/Set No. indicator again. This commands the drive to clear the fault and return
to normal operation.
a. If the fault clears, you may resume operation. Note the occurrence of the fault in the system
log so it can be used in future system fault analysis.
b. If the fault recurs, call your Customer Services engineer.

Environmental Stabilization
Environmental stabilization includes humidity and temperature stabilization. When the RA7x–RK
removable disk drive arrives at your site or is temporarily removed from its normal operating
environment, it must be environmentally stabilized prior to operation. The RA7x–RK removable
disk drive can be stabilized inside or outside the RA70–CK carrying case. However, do not insert
the canister into the SA70R–AK enclosure until it is fully stabilized.
CAUTION
Failure to environmentally stabilize the RA7x–RK removable disk drive could result in
damage to the drive media or associated electronics at power-up.
Environmental stabilization begins when the equipment enters the room where it is to be operated.
If the equipment is new, remove the outer shipping carton and allow environmental stabilization
time with the barrier bag still sealed and the desiccant in place. Refer to Table A–1 for minimum
stabilization times.
NOTE
If condensation is visible on the outside of the canister, stabilize the disk drive in
the operating environment for 6 hours or until the condensation is no longer visible,
whichever is longer.
If no condensation is visible on the outside of the canister, refer to Table A–1 for the
correct environmental stabilization time.
