Attention:
  • This procedure is not a stand-alone procedure. Customer disruption and damage to the hardware might occur when microcode and power boundaries are not in the proper conditions for this service action.
  • If a serviceable event FRU repair directed you to this procedure, the microcode and power boundaries are already set.
  • If a serviceable event FRU repair did not direct you to this procedure, see MAP1230 Replace a FRU without using a serviceable event.
Notes:
  • All the cables and FRUs to be removed must be uniquely identified so they can be reinstalled correctly.
  • If an installed earthquake resistance kit prevents you from accessing this FRU, refer to MAP1600.

Procedure

  1. Verify that the CEC enclosure is in the "power off" state before you continue. (The CEC enclosure should already be in the power off state.)

    If you have not already located the FRU to be replaced, use the location code listed in the serviceable event FRU list. See MAP1245 Finding FRUs by using location codes.

  2. At the rear of the storage facility, view both CEC enclosure power supplies.
