This service action requires you to:
v Turn off the node.
v Disconnect the power cables.
Make careful note of the layout of the cables as you go through this procedure as you must replace them
in the same position when you replace the operator-information panel assembly.
Perform the following steps to remove the operator-information panel:
1. Read the safety information to which "Preparing to remove and replace parts" on page 26 refers.
2. Follow the procedure in MAP 5350 in the IBM System Storage SAN Volume Controller Troubleshooting
Guide to verify that the node data is mirrored and synchronized, and that there are no dependent
volumes before turning off the node.
3. Slide the node out on its slide rails to the fully extended position.
You can perform most service actions when the node is fully extended from the rack on its slide rails.
You can leave the Fibre Channel and Ethernet cables connected, if you are using the
cable-management arm and if you are not removing the node from the rack. If the location of the
node in the rack is too high or too low to work comfortably, you can remove the node from the rack.
4. When the node is completely turned off, remove the cable-retention brackets and disconnect the
power cables, as described in "Removing the cable-retention bracket" on page 34.
5. Optional: If you must remove the node from the rack to work on it, perform the following procedure
to remove all cables and remove the node from the rack:
a. To make sure that you can replace all cables in the same ports from which they were removed,
label the port position of each Fibre Channel and Ethernet cable; then remove all cables from the
back of the node.
b. 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.
6. From the rear of the operator-information panel assembly, disconnect the cable.
7. Use an object to push down on the release tab ( 2 in Figure 211 on page 217).
|
Hold down the release tab and push the blue push point on the rear of the panel toward the front of
|
| the node.
