Step 1: Removing the SAS controller
CAUTION:
Do not remove a SAS controller from the chassis while the
controller status LED is green. Removing an active SAS controller
(green LED) may result in data loss.
1. From the se
rvers, stop all access to the enclosure. (Optional in
dual cont
roller configurations.)
2. Label eac

with its p
ort number. This ensures proper re-connection after
complet
ingthecachemodulereplacement.
3. Remove the SAS cables from the SAS controller.
4. Remove the SAS controller from the chassis:
a. Squeeze the controller thumb latch (1) and rotate the latch
handle down (2).
b. Pull the controller straight out of the chassis (3).
IMPORTANT:
As you pull the controller out of the enclosure, keep it level
until it is completely out of the chassis. If the controller is
tilted, it is possible to catch a component on the chassis
edge and damage the controller.
