Removing the SAN Volume Controller 2145-8A4 operator-information panel cable
Use these instructions when you are prompted to remove the operator-information panel cable from the
SAN Volume Controller 2145-8A4.
Make careful note of the layout of the cables as you go through this procedure as they will need
replacing in the same position when you replace the operator-information panel cable.
Attention:
It is easier to remove the operator-information panel cable if you first remove the service
controller, disk drive, and the backplane. If you decide to do that, see “Removing the disk drive” on page
110 before using this procedure.
Perform the following steps to remove the operator-information panel cable:
1. Turn off the node while ensuring that its data is mirrored and synchronized. See MAP 5350 in the
IBM System Storage SAN Volume Controller Troubleshooting Guide for more information.
2. Remove the cable-retention bracket and disconnect the power cable. To make sure that you can
replace all cables in the same ports from which they were removed, record the position of all Fibre
Channel and Ethernet cables; then remove all external cables from the node. See “Removing the
cable-retention bracket” on page 34.
3.
Remove the node from the rack and place it on a flat, static-protective surface. See “Removing the
SAN Volume Controller from a rack” on page 46.
4. Optionally, remove the service controller and pull the disk drive slightly out of the node to
disengage it from the backplane. You can then lift the backplane out of the way when you remove
the cable.
5. Remove the top cover. See “Removing the top cover” on page 77.
