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 back plate. If you decide to do that, see Removing the disk drive 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: Powering off a SAN Volume Controller node 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.
  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.
  4. Optionally, remove the service controller and pull the disk drive slightly out of the node to disengage it from the back plate. You can then lift the back plate out of the way when you remove the cable.
  5. Remove the top cover. See Removing the top cover.
  6. Disconnect the light-panel cable Reference key one and the USB cable Reference key two from the operator-information panel board shown in Figure 1.

  7. The operator-information panel cable consists of two thick cables and a number of thinner cables that are bundled together and routed through the chassis. It provides connectivity for the operator-information panel and the front USB ports. Trace this cable assembly through to the right side of the system board (next to the power supply) and disconnect the Front USB connector Reference key one and the operator-information panel connector Reference key two from the system board shown in Figure 2.

  8. Rotate (lift) the air deflector out of the way. It is easier to access the cable if you lift the back plate out of the way. You do not need to remove either SATA disk cable.
  9. Remove the operator-information panel cable assembly from the retention-clip next to the air deflector, but leave the power-supply cable in the retention-clip.
  10. A tie-wrap holds the cable assembly to the mounting bracket for the rightmost fan (when viewed from the front of the node and ignoring the fan on the power supply). Cut this tie-wrap to release the cable assembly.
  11. Carefully extract the cable assembly from the node. To do this, you must displace other cables; particularly, the optical drive cables, power-supply cables, and the SATA cables. Minimize disruption to these cables as much as possible.
