2–10 Replacement Procedures
3. Run FMU to obtain the last failure codes, if desired.
NOTE: If you initialized a container with the SAVE_ CONFIGURATION switch, you
can save this controller’s current device configuration using the CONFIGURATION
SAVE command. If CONFIGURATION SAVE is not used, you will have to manually
configure the new controller as described in
HSZ80 ACS Version 8.3 Configuration
and CLI Reference Guide
.
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 controller. Wear a snug-fitting,
grounded ESD wrist strap.
The cache module may contain unwritten data if the controller crashed
and you weren’t able to shut it down with the SHUTDOWN
THIS_CONTROLLER command.
5. Remove the program card’s ESD cover and program card. Save them for the
replacement controller.
6. Remove the trilink connectors, but don’t disconnect the host bus cables (or
terminators) from the trilink connectors.
NOTE: One or two trilink connectors may be attached, depending on the
configuration.
7. If connected, disconnect the PC or terminal from the controller’s maintenance
port.
8. Disengage both retaining levers and remove the controller, then place the
controller into an antistatic bag or onto a grounded antistatic mat.
