Notes:
  1. Call your next level of support.
  2. Old-level battery modules have captive screws to fasten the module into the battery module enclosure. New-level battery modules do not use captive screws and instead use a loose screw FRU P/N 00G1268. The FRU kit for the new-level modules includes the screws. The screws can be ordered separately if needed.

Notes:
  1. The cable interface between the fan sense card and the rear of the storage enclosure consists of three segments:
    1. The cable from the fan sense card to the rack center wall bulkhead. This FRU is a four-cable harness.
      Individual cables cannot be replaced.
    2. The rack center wall bulkhead which is between the PPS power supplies and the storage enclosure vertical air plenum.
      This FRU should never fail, and requires the rack to be powered off to replace it.
    3. The cable from the rack center wall bulkhead to the rear of the storage enclosure. This FRU is a Y-cable.
      One leg of the Y carries fan sense card signals from the rack center wall bulkhead to the storage enclosure.
      The other leg of the Y carries 5/12v power from the center wall bulkhead to the storage enclosure.
  2. Expansion rack only.
