Safety Precautions
2.1 Introduction
This chapter discusses hazards and safety precautions that the Digital Services engineer
should be aware of before installing SA70–CK kit, SA70–LK/MK, SA71–NK/PK, SA72–
NK/PK, and SA73–NK/PK options into the VAX 6000-series processor cabinet.
Warning
Only qualified Digital Services engineers should perform these procedures. Digital
customers may access the SA70–LK/MK, SA71–NK/PK, SA72–NK/PK, or SA73-NK/PK
operator control panel only through the VAX 6000 OCP access panel on the front door.
Access to the options by opening the front or rear cabinet doors is prohibited.

2.2 Hazards and Safety Precautions
The front door of a VAX 6000-series processor cabinet is considered a safety barrier. High
voltages, as well as the blower assembly, are accessible once the front door is opened. The
cabinet door is locked and cannot be opened without a 5/32 hex key. Only Digital Services
engineers can open the front door without violating Digital safety measures.
SA7x enclosure line voltage switches come preset in the 220V/50Hz position as a safety
precaution. Ensure the line voltage switch is set to the proper position for the installation.
Refer to Chapter 3.

2.3 ESD Precautions
Only Digital Services engineers with training in electrostatic discharge (ESD) procedures
should install an SA7x enclosure or work with the processor cabinets.
Digital Services engineers must wear proper ESD protective ground straps connected to a
good ground when accessing, installing, or repairing SA7x enclosures or VAX 6000-series
processor cabinets. ESD kits, containing protective ground straps, are behind the front and
rear doors of the processor cabinets. Use this ground strap when working with the processor
cabinets. Use a separate ground strap connected to the SA7x enclosure when working with
the SA7x enclosure.

3.2 Powering Down the Cabinet
The VAX 6000-series processor cabinets use H405 power controllers. To remove power from
the cabinet, use the following procedure:
1. Locate the cabinet control panel in the upper-left corner of the front door. The cabinet
control panel is shown in Figure 3–3.
2. With the console key, turn the Standby/Enable/Secure control switch to 0.
3. Turn the Update/Halt/Auto Start control switch to Halt.
4. Go to the rear of the cabinet.
5. Locate the H405 power controller.
6. Remove power from the cabinet by pulling the power controller main circuit breaker Thandle located on the H405 power controller. Refer to Figure 3–3.
7. Unplug the cabinet power cord from the ac receptacle.

3.3 Installing H405–E or –F Power Controllers
Note
Replacing the H405–E/F VAX 6000 power controller may be necessary for VAX 6000
SA7x embedded storage installations. To determine if this procedure is necessary,
carefully follow the instructions in this section.

Installing the SA7x embedded storage options may require replacing the H405–E/F VAX 6000
power controller.
Some VAX 6000 system cabinets may contain H405 power controllers with switched ac outlets.
Replace any of these H405–E/F power controllers with the H405–E/F power controllers in the
62X34–UA/UB upgrade kits.
The H405–E/F power controller in the 62X34–UA/UB upgrade kit provides unswitched ac
outlets with some electrical enhancements for proper operation of the SA7x options as
embedded storage in the VAX 6000 cabinet.

3.3.1 Determining if H405–E/F Replacement Is Necessary
To determine of the H405–E/F replacement is necessary:
1. Perform an orderly system shutdown (Section 3.2).
2. Turn the upper key switch on the front control panel to the "0" position.
3. From the rear of the VAX 6000 system cabinet, locate the H405 power controller (lowerright corner) and remove power using the main circuit breaker. (See Figure 3–3.)
4. Unplug the system power cord from its receptacle.
5. Wait 2 minutes for all components to discharge.

4.2.1 Master On/Off Switch
The master on/off rocker switch for the SA7x enclosure is located in the center of the rear
panel. Setting the switch to 1 applies power to the SA7x. Setting the switch to 0 removes
power from the enclosure.

4.2.2 Line Voltage Select Switch
As you face the rear panel, the line voltage select switch is located to the right of the master
on/off switch. It is visible through a hole in the rear panel. This switch is set to the available
line voltage during installation. The selected voltage is shown on the switch element.
CAUTION
The SA7x enclosure power supply is universal for both 120 Vac at 60 Hz or 240 Vac at
50 Hz. The power supply is set to 240 Vac at 50 Hz at the factory and must be reset
to 120 Vac at 60 Hz for some installations. Selecting 120 Vac at 60 Hz and using 240
Vac at 50 Hz will damage the supply.

4.2.3 Fault/Over-Temperature Indicator
A red Fault indicator is visible, when lit, through holes in the upper right-hand rear corner
of the power supply. The enclosure automatically shuts down when it detects a fault or overtemperature condition. If the fault indicator illuminates, turn the master on/off switch to 0
and call Digital Services.

Chapter 5
Powering Up the SA7x Enclosure
This chapter explains how to use the SA7x enclosure and drives and how to set the unit
number.

5.1 Powering Up the SA7x Enclosure
Apply power to the enclosure as follows:
1. Verify that the drive power switches on the front panel of the enclosure are set to off
(switch button released).
2. Set the master on/off switch to 1.
3. Verify the power is on by checking that the fan starts and normal airflow exists through
the enclosure.
Note
Air may flow through the enclosure without output voltage. This indicates the line
voltage select switch is in the wrong position. Set the master on/off switch to 0 and
set the line voltage select switch to the correct switch setting.

5.2 Placing a Drive On Line
After applying power to the SA7x enclosure, power up and bring each disk drive in the
enclosure on line by performing the following steps:
1. Locate the drive power switches. Refer to Figure 4–1.
2. Press the drive power switch for the desired drive. If power to the drive is within
specifications, the green switch element indicator illuminates.
Note
Setting a disk drive power switch does not spin up the associated drive.

illuminate for about 8 seconds. Then:

All indicator lights

a. If the drive completes the power-on diagnostics without detecting a fault, all indicators
go out.
b. If the Fault/Set No. indicator remains on, the drive has detected a fault. Press the
Fault/Set No. switch to clear the fault.
3. Press the Run switch on the operator control panel to spin up the drive.
Figure 4–1. The following sequence of indicator lights occurs during spin up:

Refer to

a. The Run indicator illuminates. If you power up the drive with the Run switch set,
release and press the Run switch again or issue a MOUNT command from your
system to initiate spin up. The Run indicator illuminates to show that spin up was
initiated through either of these actions.
b. All other indicators remain off.
c.

When the drive has spun up, the Ready indicator illuminates. The Ready indicator
then flashes while the internal read/write and seek diagnostics run. When the
diagnostics are complete, the Ready indicator remains on.

d. The Fault/Set No. indicator illuminates if the drive detects a fault during spin up.
Press the Fault/Set No. to clear the error.
4. Select Port A, Port B, and Write Protect switches, as required. These functions are
disabled by pressing the switch a second time.
The Ready and Run indicators remain lit during normal operation, though the Ready
indicator may flicker during heavy seeks. The Write Protect indicator is on if the drive is
write protected, off if the drive is write enabled. The Port A and Port B indicators illuminate
only while their respective ports are selected by the system controller.

5.3 Placing a Drive Off Line
To place a drive off line:
1. Press and release the Port A and B switches to disable both ports of the disk drive. Refer
to Figure 4–1.
2. Wait for the port indicators to go out.
To place a drive off line for drive removal:
1. Press and release the Port A and B switches to disable both ports of the disk drive. Refer
to Figure 4–1.
2. Wait for the port indicators to go out.
3. Press and release the appropriate Run switch on the operator control panel. Wait for the
Run indicator to go out.
4. Set the drive power switch to Off. The switch element light goes out.

5.4 Setting the Unit Number
The unit number for any drive can be set at the operator control panel. This is the number
by which the drive is known to the system. Once the number is in the drive, the system
controller reads it according to the controller’s protocol.
You must take a drive off line before changing its unit number. You do not need to take any
other drives in the enclosure off line while setting a specific drive unit number, nor do you
need to spin down the selected disk to change the unit number. When the operator control
panel is in unit select mode, all drives not spun down continue to operate according to the
settings of the operator control panel switches.
To set the unit number:
1. Dismount the disk, using the proper system commands.
2. Place the desired drive off line according to the procedures in Section 5.3. Do not set the
drive power switch to Off.
3. Press the Unit Select switch with a pen or small screwdriver. The unit select numbers
for all powered-on drives in the enclosure flash to indicate that the operator control panel
is in unit select mode.
4. Press the Fault/Set No. switch once to increment the unit number by one.
Press and hold the Fault/Set No. switch to rapidly increment the unit number for that
drive. Set the unit number between 000 and 255.
Note
You cannot decrement a drive number. Holding the Fault/Set No.
increments to 255, then starts at 0 again.

switch

5. Repeat that step for all drives for which you are changing numbers. If you do not press
the Fault/Set No. switch, the number remains the same as before you entered the unit
select mode.
6. After setting the unit numbers, restore the operator control panel to normal operation by
pressing the Unit Select switch again.
7. Restore the off-line drive to its on-line status. Refer to Section 5.2.
8. Remount the disk drive, using the proper system commands.
After the SA7x enclosure powers up, passes internal diagnostics, and has the unit number
set, run the SA7x/KDB50/KDM70 diagnostics to ensure the configuration is operational.

load the first add-on drive into the left position (position 3). Load the second add-on drive
into the right position (position 4).
Refer to Figure 6–1 and use the following procedure to install the RA7x disk drive into an
SA7x enclosure.
1. Ensure power has been removed from the enclosure. Refer to Section 6.2.
2. Remove the SA7x enclosure front cover. The front cover is attached to the enclosure with
two captive half-turn screws. Loosen the screws and lift the front cover up and out.
3. RA7x add-on disk drives arrive at the customer site with the drive shoeplate installed for
manufacturing purposes. The shoeplate needs to be reversed for enclosure applications.
Remove four screws, two per side, from the drive shoeplate. Reverse the shoeplate and
reinstall the four screws.
4. Orient the unpacked RA7x disk drive so that the drive shoeplate and enclosure shoeplate
guide are on the same side.
5. Hold the connectors clear of the drive and slide the disk drive into the selected position
in the enclosure.
6. Verify the shoe plate retaining clip has locked the drive in position.
