Replacing the MSA1000 Controller Cache
Caution: It is important to follow these instructions when replacing
components in the MSA1000. If the procedure is done improperly, it is
possible to lose data or damage equipment. Refer to Appendix B,
“Electrostatic Discharge,” for important information on using the proper
procedures.
Note: If your system is equipped with a single controller, and you must replace the
controller cache, you must power down the system first. If your system is equipped with
two controllers, and you want to replace a failed cache module with another of the
same size, you can replace the module while the system is running. If your system is
equipped with two controllers, and you are replacing the cache module with a module
of a different size, you must power down the system first, and then change the cache
module on both controllers at the same time.
1. Press the controller’s thumb latch and pull the latch handle towards you 1.
See Figure 26.
2. Remove the MSA1000 Controller by pulling it straight out of the chassis 2.
