Removing the SAN Volume Controller 2145-8G4 operator-information panel

assembly

You might have to remove the operator-information panel assembly on a SAN Volume Controller

2145-8G4 due to required maintenance.

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 assembly.

Perform the following steps to remove the operator-information panel:

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 2145 Troubleshooting Guide for more information.

2. Remove the cover and open the fan door. See “Removing the top cover” on page 68.

3. Release the dummy CD/DVD drive

by pressing the release button

and sliding the drive out

approximately 2 cm (1 in), as shown in Figure 207 on page 191. It is possible to push the drive from

the back to start it moving. Do not remove the drive from the casing.
