Replacing a Cache Module
Use this procedure for the following configuration:
HSZ80 ACS Version 8.1 Dual-Redundant Controller
Use the following steps in “Removing a Cache Module” and
“Installing a Cache Module” to replace a cache module.
NOTE: The new cache module must contain the same amount
of memory as the module it’s replacing.
Removing a Cache Module
Use the following steps to remove a cache module:
1. Connect a PC or 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.”
2. Disable failover and take the controllers out of their dual-
redundant configuration with the following command:
SET NOFAILOVER
3. Start FRUTIL with the following command:
RUN FRUTIL
4. Enter option 1, Replace or remove a controller or cache
module, from the FRUTIL Main menu:
FRUTIL Main Menu:
1. Replace or remove a controller or cache module
2. Install a controller or cache module
3. Replace other cache module battery
4. Replace a PVA module
5. Replace an I/O module
6. Set battery life to new
7. Exit
Enter choice: 1, 2, 3, 4, 5, 6, or 7 -> 1
5. Enter option 3, Other cache module, from the Replace or
Remove Options menu:
Replace or remove 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
6. Confirm that you want to remove the other cache module.
FRUTIL displays the following:
Remove the slot A [
or B
] cache module? Y/N
7. Enter Y(es) and press return.
8. Wait for FRUTIL to quiesce the device ports. After the ports
have been quiesced (this may take several minutes), FRUTIL
displays the following:
All device ports quiesced.
Remove the slot A [
or 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 two minutes, “this
controller” will exit FRUTIL and resume operations.
CAUTION: ESD can easily damage a cache module. Wear a
snug-fitting, grounded ESD wrist strap.
9. Disengage both retaining levers and partially remove the
other cache module—about half way.
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—the status light is not lit
and is not blinking—before disconnecting the ECB cable from
the cache module. Failure to disable the ECB could result in
cache module damage.
11. Disconnect the ECB cable from the other cache module,
remove the cache module, and place it onto a grounded mat
or into an approved antistatic bag.
12. Once the cache module is removed, FRUTIL displays the
following:
Restarting all device ports. Please wait...
.
.
.
Do you have a replacement cache module? Y/N
NOTE: Remove the DIMMs from the cache module. They will be
installed in the replacement 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.
Repeat for all DIMMs.
Installing a Cache Module
Use the following steps to install a cache module:
NOTE: If you selected Y(es) in step 12 of “Removing a Cache
Module,” go to step 5.
1. Connect a PC or 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.”
2. Start FRUTIL with the following command:
RUN FRUTIL
3. Enter option 2,Installa controller or cache module, from the
FRUTIL Main menu:
FRUTIL Main Menu:
1. Replace or remove a controller or cache module
2. Install a controller or cache module
3. Replace other cache module battery
