Installing HSZ80 DIMMs
The HSZ80 cache module can contain 64MB (2 x 32MB),
128MB (4 x 32MB), 256MB (2 x 128MB), or 512MB
(4 x 128MB) of memory (see Figure 4).
Follow these instructions to replace DIMMs in a single
controller or dual-redundant controller configuration.

Removing DIMMs in a Dual-Redundant Controller
Configuration
Follow these steps to remove DIMMs.
1.

Connect a terminal to the operational controller’s
maintenance port. The controller to which you’re connected
is “this controller;” the controller whose cache module
you’re replacing is the “other controller.”

Remove the slot B cache module within x minutes, xx
seconds. Then disconnect the external battery, if in
use, from the cache module.

NOTE: A countdown timer allows a total of two minutes to
remove the cache module. If you exceed the two minutes, “this
controller” will exit FRUTIL and resume operations.

Figure 3. Inserting a DIMM into Its Slot

Disengage the two retaining levers and remove the other
cache module, then place the cache module onto a grounded
antistatic mat.

10. Disable the ECB by pressing the battery disable switch until
the status light stops blinking—about five seconds.
CAUTION: The ECB must be disabled—status light not lit or
blinking—before disconnecting the ECB cable from the cache
module. Failure to do so could result in the cache module being
shorted out.
11. Disconnect the external cache battery (ECB) cable from the
other cache module.

13. Press down on the DIMM retaining levers at either end of the
DIMM you want to remove.
14. Grasp the DIMM and gently remove it from the DIMM slot.
Installing DIMMs in a Dual-Redundant Controller
Configuration
Follow these steps to install DIMMs.
1.

64MB configuration (2 x 32 MB)
256 MB configuration (2 x 128 MB)

Insert the DIMM straight into the socket and ensure that the
notches in the DIMM align with the tabs in the socket as
shown in Figure 3.

Press the DIMM gently until it’s seated in the socket.

Double-check to ensure both ends of the DIMM are firmly
seated in the slot and both retaining clips engage the DIMM.

NOTE: If you selected Y(es) in step 12 in the removal
procedure—for a continuous removal and installation—go to
step 8.
4.

Connect a local terminal to the operational controller. The
controller to which you’re connected is “this controller;” the
controller whose cache module you’re installing is the “other
controller.”

14. Enable failover, and re-establish the dual-redundant
configuration with the following command:

Start FRUTIL with the following command:
RUN FRUTIL

SET FAILOVER COPY=THIS_CONTROLLER

Choose option 2, Install a controller or cache module, from
the FRUTIL Main Menu:

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

7. Exit

Enter choice: 1, 2, 3, 4, 5, 6, or 7 -> 2

Removing DIMMs in a Single Controller Configuration
Follow these steps to remove DIMMs.

Choose option 3, Other cache module, from the Install
Options menu to install the other cache module:

From the host console, dismount the logical units in the
subsystem. If you are using a Windows NT platform, shut
down the PC.

If the controller is operating, connect a terminal to the
controller’s maintenance port.

Run FMU to obtain the last failure codes, if desired.

Install Options:
1. Other controller and cache module
2. Other controller module
3. Other cache module
4. Exit
Enter choice: 1, 2, 3, or 4 -> 3

If the controller is not operating, go to step 5.

Confirm that you want to install the other cache module.
FRUTIL displays the following:

Insert the slot B cache module? Y/N

Shut down the controller with the following command:
SHUTDOWN THIS_CONTROLLER

Type Y(es) and press return.

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

10. Wait for FRUTIL to quiesce the ports. After the ports have
been quiesced (this may take several minutes), FRUTIL
displays the following:

All device ports quiesced.

Turn off the power to the subsystem.

NOTE: A countdown timer that allows a total of two minutes to
install the cache module. If you exceed the two minutes, “this
controller” will exit FRUTIL and resume operations.

6.
CAUTION: An electrostatic discharge (ESD) can easily damage
a cache module. Wear an ESD wrist strap on your wrist, make
sure the strap fits snugly, and attach the ESD strap's grounding
lead to a verified earth ground.

Disable the ECB by pressing the battery disable switch until
the status light stops blinking—about five seconds.

CAUTION: The ECB must be disabled—status light not lit or
blinking—before disconnecting the ECB cable from the cache
module. Failure to do so could result in the cache module being
shorted out.

11. If not already done, disable the ECB to which you’re
connecting the new cache module by pressing the battery
disable switch until the status light stops blinking—about
five seconds.

Disconnect the external cache battery (ECB) cable from the
cache module.

8.
CAUTION: The ECB must be disabled—the status light is not lit
or is not blinking—before connecting the ECB cable to the cache
module. Failure to do so could result in the ECB being shorted
out.

Disengage the two retaining levers, and remove the cache
module, and place the cache module onto a grounded
antistatic mat.

Press down on the DIMM retaining levers at either end of the
DIMM you want to remove.

12. Connect the ECB cable to the new cache module. Follow the
VHDCI Cable Precautions.

10. Grasp the DIMM and gently remove it from the DIMM slot.

13. Insert the cache module into its slot and engage its retaining
levers.

Installing DIMMs in a Single Controller Configuration
Follow these steps to install DIMMs.
1.

Insert the DIMM straight into the socket and ensure that the
notches in the DIMM align with the tabs in the socket as
shown in Figure 3.

Press the DIMM gently until it’s seated in the socket.

Double-check to ensure both ends of the DIMM are firmly
seated in the slot and both retaining clips engage the DIMM.
Figure 4 shows the cache-module memory configurations for
an HSZ80 array controller.

CAUTION: An electrostatic discharge (ESD) can easily damage
a cache module. Wear an ESD wrist strap on your wrist, make
sure the strap fits snugly, and attach the ESD strap’s grounding
lead to a verified earth ground.
Make sure you align the cache module in the appropriate card
cage guide rails. If you do not align the modules appropriately,
damage to the backplane can occur.
4.

Insert the cache module into its slot, and engage its retaining
levers.

CAUTION: The ECB must be disabled—the status light is not lit
or is not blinking—before connecting the ECB cable to the cache
module. Failure to do so could result in the ECB being shorted
out.
5.

Connect the ECB cable to the cache module. Follow the
VHDCI Cable Precautions.

If not already connected, connect a terminal to the
controller’s maintenance port.

Restore power to the subsystem. The ECB automatically reenables itself to provide backup power to the cache module.
The controller will restart with the configuration that resides
in its nonvolatile memory.

Mount the logical units on the host. (If you are using a
Windows NT platform, restart the PC.)

Set the subsystem date and time.
