Replacing the Cache Module in a Single Controller Configuration
Use the following steps in “Removing the Cache Module in a Single
Controller Configuration” and “Installing the Cache Module in a Single
Controller Configuration” to replace the cache module.
Removing the Cache Module in a Single Controller
Configuration
Use the following steps to remove the cache module:
1. From the host console, dismount the logical units in the subsystem. If
you are using a Windows NT platform, shut down the server.
2. If the controller is operating, connect a PC or terminal to the controller’s
maintenance port.
If the controller is not operating, go to step 5.
3. Run FMU to obtain the last failure codes, if desired.
4. Shut down the controller with the following command:
SHUTDOWN THIS_CONTROLLER
When the controller shuts down, its reset button and the first three LEDs
are lit continuously.
Caution ESD can easily damage a cache module. Wear a snug-fitting,
grounded ESD wrist strap.
5. 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 or is not
blinking—before disconnecting the ECB cable from the cache module.
Failure to disable the ECB could result cache module damage.
6. Disconnect the ECB cable from the cache module.
7. Disengage both retaining levers, remove the cache module, and place
the cache module into an antistatic bag or onto a grounded antistatic
mat.
