Removing a SAN Volume Controller 2145-8A4 power supply

This topic describes how to remove a SAN Volume Controller 2145-8G4 power supply.

Take precautions to avoid damage from static electricity. Wear an anti-static wrist strap and use a static-protected mat or surface. For more information, see Handling static-sensitive devices.
To remove the power supply, perform the following steps:
Notes:
  • The air deflector also functions as the back plate latch. In this procedure, you must lift the air deflector to access some of the cables.
  • Notice the routing of all power-supply cables. You will route the power-supply cables the same way when you install the power supply.
  1. Read the safety precautions in Safety and environmental notices.
  2. 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.
  3. Remove the cable-retention bracket and disconnect the power cable from the node. See Removing the cable-retention bracket.
  4. Remove the node from the rack and place it on a flat, static-protective surface. See Removing the SAN Volume Controller from a rack.
  5. Remove the top cover. See Removing the top cover.
  6. Remove the SATA back plate far enough to disconnect the two power cables from it. See Removing the disk-drive backplane.
  7. Disconnect the power-supply cables from the 24 PIN POWER connector reference key one and the POWER connector reference key two on the system board, as shown in Figure 1.

  11. Loosen the captive thumbscrew reference key one that secures the rear of the power supply to the chassis bottom.
  12. Lift the power supply reference key two out of the bay.
