Verifying component failure
Before replacing the controller, cache module, or battery pack:
• Check the contr
oller LCD display panel for error messages.
• Record any Failure LEDs or LCD panel messages for reference purposes.
• Check the controller Heartbeat LED (1).IftheLEDisnotblinking,itmightindicateafailure.
• Check the cont
roller Fault LED (2) . If the LED is on, it might indicate a failure.
Removing the controller
1. Review all warnings, cautions, and preparation procedures as detailed in Warnings and precautions.
2. Review all controller-specific warnings, cautions, and preparation procedures as detailed in Before
you begin.
3. In single-controller configurations, schedule an maintenance window for the service. For instructions
on shutting down the MSA, see Powering off the MSA1510i.
4. In operational dual-controller configurations, access a management utility, such as the MSA
Command Line Interface (MSA-CLI) or Storage Management Utility (SMU) and disable the controller
being removed. For instructions, see online help. (During this procedure, because one of the two
controllers is being removed, the MSA operates in a non-redundant mode.)
5. Press the controller thumb latch and rotate the latch handle out (1).
6. Pull the controller straight out of the chassis (2).

If your system is equipped with two controllers:
