Installing an HSZ80 External Cache Battery (ECB)
Follow these instructions to replace an ECB in a single
controller or dual-redundant controller configuration. See
the HSZ80 Array Controller ACS Version 8.x User’s
Guide for instructions on upgrading a subsystem to a
dual-redundant controller configuration.

Replacing an External Cache Battery
Storage Building Block in a DualRedundant Controller
Configuration

Start FRUTIL with the following command:
RUN FRUTIL

Follow these steps to replace an external cache battery (ECB)
storage building block (SBB) (see Figure 1):

Choose option 3, Replace other cache module battery, from
the FRUTIL Main Menu:
FRUTIL Main Menu:
1. Replace or remove a controller or cache module
2. Install a controller or cache module

Confirm that you have a new dual-battery replacement ECB
SBB. FRUTIL displays the following:
Type Y(es) and press return.

NOTE: If an empty slot is not available, place the new ECB SBB
on the top of the cabinet.
7.

Confirm that you want to install a replacement ECB SBB.
FRUTIL displays the following:
Replace the battery for the cache module in slot A

CAUTION: Do not disconnect the old ECB until the batteries in
the new ECB are fully charged.

(or B)? Y/N

Type Y(es) and press return.

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 cabinet. After the old ECB SBB
has been removed, carefully insert the new ECB SBB into the
empty slot.

Insert the new ECB SBB into an empty slot.

10. Connect the open end of the ECB “Y” cable to the new ECB.

Connect a local 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 and take the controllers out of their dualredundant configuration with the following command:
SET NOFAILOVER

CAUTION: The ECB cable has a 12-V and a 5-V pin. Improper
handling when connecting or disconnecting could cause these
pins to contact ground, resulting in the cache module being
shorted out.

CAUTION: Do not disconnect the old ECB until the batteries in
the new ECB are fully charged. The new ECB’s status light will
be lit continuously to indicate that its batteries are fully charged.
A blinking status light indicates that its batteries are charging.
You may operate the subsystem regardless of the old ECB’s
status.

11. Wait until the new ECB’s status light is on continuously,
then disconnect the ECB cable from the old ECB.

CAUTION: Do not disconnect the old ECB until the batteries in
the new ECB are fully charged.

FRUTIL displays the following:

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

Connect a local terminal to the controller’s maintenance
port.

Shut down the controller with the following command:

Setting battery A (or B) state to new.
Testing battery attached to cache module A (or B).
Test complete. Battery is good.

12. Wait for FRUTIL to terminate.
13. Enable failover, and re-establish the dual-redundant
configuration with the following command:

SHUTDOWN THIS_CONTROLLER

When the controller shuts down, its reset button and first
three LEDs are lit continuously.

SET FAILOVER COPY=THIS_CONTROLLER

This command copies the subsystem’s configuration from
“this controller” to the “other controller.”
14. Disconnect the local terminal from the controller and
connect it to the other controller.

Turn off the power to the subsystem.

Insert the new ECB SBB into its slot.

CAUTION: The ECB cable has a 12-V and a 5-V pin. Improper
handling when connecting or disconnecting could cause these
pins to contact ground, resulting in the cache module being
shorted out.

15. To connect the other cache module to the new ECB SSB,
repeat steps 2 through 8. Since the new ECB SBB is already
installed, skip step 9, and then repeat steps 10 through 12.
Now both cache modules are connected to the new ECB
SSB.
16. 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 cabinet, carefully insert it now into
the empty slot.

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

Restore power to the subsystem. The controller
automatically restarts.

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.”

Replacing the External Cache Battery
in a Single Controller Configuration

Wait until the new ECB’s status light is on continuously,
then disconnect the ECB cable from the old ECB.

Start FRUTIL with the following command:
RUN FRUTIL

Follow these instructions to remove and replace a single-battery
external cache battery (ECB) storage building block (SBB) (see
Figure 2):

10. An internal clock monitors the life of the battery. When
replacing a battery this clock must be reset. Choose option 6,
Set battery life to new, from the FRUTIL Main Menu to reset
the internal clock.
