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 all single-controller conﬁgurations, power off the MSA as instructed in Removing power from

the MSA.

4. In operational dual-controller conﬁgurations, access an MSA management utility, such as the

MSA Command Line Interface (MSA-CLI) or the Array Conﬁguration Utility (ACU) 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).
