Installing an External Cache Battery (ECB)
The HSZ70, the HSG80, and the HSZ80 all use the same ECB. This document contains instructions to replace an ECB in an HSZ70
HSOF Version 7.x Array Controller, the HSG80 ACS Version 8.x Array Controller, and the HSZ80 ACS Version 8.x Array Controller. See
the appropriate HSZ70 Array Controller HSOF Version7.x Service Manual, HSG80 Array Controller ACS Version 8.x User’s Guide,
HSZ80 Array Controller ACS Version 8.x User’s Guide, HSG80 Array Controller ACS Version 8.x Maintenance and Service Guide, or
HSZ80 ACS Version 8.x Maintenance and ServiceGuide for instructions on upgrading a single-controller configuration to a
dual-redundant controller configuration.

Replacing an External Cache Battery Storage
Building Block

NOTE: This procedure assumes that a single ECB SBB with a
dual battery is installed and an empty slot is available for the
replacement ECB SBB. If an empty slot is not available, place
the new ECB SBB on the top of the enclosure. After the old ECB
SBB has been removed, carefully insert the new ECB SBB into
the empty slot.

Use this procedure for the following configurations:

HSZ70 HSOF Version 7.x Dual-Redundant Controller
HSG80 ACS Version 8.0 Dual-Redundant Controller
HSZ80 ACS Version 8.1 Dual-Redundant Controller

Connect a PC or terminal to the controller with the
operational ECB. The controller to which you’re connected
is “this controller”; the controller whose ECB you’re
replacing is the “other controller.”

Disable failover with the following command:

[HSZ70 and HSZ80] Confirm that you have a new dualbattery replacement ECB SBB. FRUTIL displays the
following:

17. Enable failover, and re-establish the dual-redundant
configuration with the following command:
SET FAILOVER COPY=THIS_CONTROLLER

This command copies the subsystem’s configuration from
“this controller” to the “other controller.”

[HSZ70 and HSZ80] Enter Y(es) and press return.
NOTE: If an empty slot is not available, place the new ECB SBB
on the top of the enclosure.

18. Disconnect the PC or terminal from the controller.

[HSZ70 and HSZ80] Confirm that you want to install a
replacement ECB SBB. FRUTIL displays the following:

You may operate the subsystem regardless of the old ECB’s
battery status, but do not disconnect the old ECB until the
batteries in the new ECB are fully charged.

Use the following steps to remove and replace an ECB SBB (see

Replacing an External Cache Battery Storage
Building Block

Insert the new ECB SBB into the empty battery slot.
NOTE: If an empty slot is not available, place the new ECB SBB
on the top of the enclosure.

Use this procedure for the following configurations:

HSG80 ACS Version 8.2 Single Controller
HSG80 ACS Version 8.2 Dual-Redundant Controller
HSG80 ACS Version 8.3 Single Controller
HSG80 ACS Version 8.3 Dual-Redundant Controller
HSG80 ACS Version 8.4 Single Controller
HSG80 ACS Version 8.4 Dual-Redundant Controller
HSZ80 ACS Version 8.3 Single Controller
HSZ80 ACS Version 8.3 Dual-Redundant Controller

Connect the new battery to the unused end of the Y cable
attached to the cache module.

Disconnect the old battery. Do not wait for the new battery’s
status light to turn solid green.

Press return.
FRUTIL displays the following:
Updating this battery's expiration date and deep
discharge history.
Field Replacement Utility terminated.

The ECB SBB can be replaced with cabinet power on or off. A
single-battery ECB SBB is shown in Figure 2 and a dual-battery
ECB SBB is shown in Figure 1.

Disconnect the PC or terminal from the controller’s
maintenance port.

If this is a dual-redundant controller configuration and you
installed a dual-battery ECB SBB and you want to connect
the other cache module to the new ECB SBB, connect the PC
or terminal to the other controller’s maintenance port. The
controller to which you’re now connected is “this controller.”

Replacing an External Cache Battery Storage Building Block with
Cabinet Power On
Use the following steps to replace the ECB SBB with the cabinet
powered on:
NOTE: The procedure for a dual-redundant controller
configuration assumes that a single ECB SBB with a dual battery
is installed and an empty slot is available for the replacement
ECB SBB. If an empty slot is not available, place the new ECB
SBB on the top of the enclosure. After the old ECB SBB has been
removed, carefully insert the new ECB SBB into the empty slot.

10. Repeat steps 2 through 8.
11. Remove the old ECB SBB.
NOTE: If an empty slot was not available, and the new ECB SBB
was placed on the top of the enclosure, carefully insert it now
into the empty slot.

Connect a PC or terminal to the controller with the ECB
SBB that you intend to replaced. The controller to which
you’re connected is “this controller.”

Start FRUTIL with the following command:

Replacing an External Cache Battery Storage Building Block with
Cabinet Power Off
Use the following steps to replace the ECB SBB with the cabinet
powered off:

RUN FRUTIL

If the controller and cache module are not operating, go to
step 4. Otherwise, go to the next step.

Connect a PC or terminal to the controller’s maintenance
port. The controller to which you’re connected is “this
controller.”

Shut down the controllers. In single controller
configurations, shut down “this controller.” In dualredundant controller configurations, shut down the “other
controller” first, then shut down “this controller” with the
following commands:

FRUTIL displays the following:
Do you intend to replace this controller’s cache
battery? Y/N

Enter Y(es). FRUTIL displays the following:
If the batteries were replaced while the cabinet was
powered down, press return.
Otherwise follow this procedure:
WARNING:Ensure that at least one battery is
connected to the Y cable at all times
during this procedure.
1.Connect the new battery to the unused end
of the 'Y' cable attached to cache A [ or B].
2.Disconnect the old battery. Do not wait for the
new battery's status light to turn solid green.
3.Press return.

SHUTDOWN OTHER_CONTROLLER
SHUTDOWN THIS_CONTROLLER

When the controllers shut down, their reset buttons and their
first three LEDs are lit continuously. This may take several
minutes, depending on the amount of data that needs to be
flushed from the cache modules.

CAUTION: The ECB cable has a 12-volt and a 5-volt pin.
Improper handling or misalignment when connecting or
disconnecting could cause these pins to contact ground,
resulting in cache module damage.

Turn off the power to the subsystem.

Insert the new ECB SBB into its slot.

CAUTION: The ECB cable has a 12-volt and a 5-volt pin.
Improper handling or misalignment when connecting or
disconnecting could cause these pins to contact ground,
resulting in cache module damage.
6.

Connect the open end of the ECB Y cable to the new ECB.

Restore power to the subsystem. The controller
automatically restarts.

Disconnect the ECB cable from the old ECB.

Start FRUTIL with the following command:
RUN FRUTIL

FRUTIL displays the following:
Do you intend to replace this controller’s cache
battery? Y/N

10. Enter Y(es). FRUTIL displays the following:
If the batteries were replaced while the cabinet was
powered down, press return.
Otherwise follow this procedure:
WARNING:Ensure that at least one battery is
connected to the Y cable at all times
during this procedure.
1.Connect the new battery to the unused end
of the 'Y' cable attached to cache A [ or B].
2.Disconnect the old battery. Do not wait for the
new battery's status light to turn solid green.
3.Press return.

11. Press return.
FRUTIL displays the following:
Updating this battery's expiration date and deep
discharge history.
Field Replacement Utility terminated.

12. Disconnect the PC or terminal from the controller’s
maintenance port.
13. In a dual-redundant controller configuration and if the ECB
was replaced for both cache modules, connect the PC or
terminal to the other controller’s maintenance port. The
controller to which you’re now connected is “this controller.”
14. Repeat steps 9 through 12.
15. Remove the old ECB SBB.
