Notes:
  • Perform the following procedure only if directed to do so by IBM® Remote Technical support or by a fix procedure in the management GUI.
  • An enclosure can have FRU P/N 01LJ112 or FRU P/N 01LJ607. When needed, an enclosure with FRU P/N 01LJ607 is used to replace FRU P/N 01LJ112.
This task assumes that the following conditions are met:

About this task

The expansion enclosure contains the drive board, signal interconnect board, and internal power cables. If a fault with the drive board or the intercanister link is suspected, you can replace the enclosure. However, you can remove the parts from the old expansion enclosure and reinstall them in the replacement enclosure.

Procedure

  1. Remove the front display (4U) and PSU (1U) fascia from the old enclosure, as described in Removing the fascia.
    1. Install the front display (4U) and PSU (1U) fascia on the new enclosure, as described in Installing or replacing the fascia.
  2. Remove the display panel assembly from the old enclosure, as described in Removing the display panel assembly.
    1. Install the display panel assembly into on the new enclosure, as described in Installing or replacing the display panel assembly.

  5. Attach the inner rail section to the new enclosure, as described in Installing or replacing the support rails.
  6. Replace the new enclosure in rack, as described in Installing a 5U expansion enclosure in a rack.
  7. Reinstall the remaining parts into the enclosure, as described in the following topics. You can install the parts in any order.
    Important: Ensure that a mechanical lift is available and in place to support the additional weight as the FRUs are reinstalled in the enclosure.
  8. Reconnect the SAS cables, as described in Removing and installing a SAS cable.
  9. Reconnect the power cables, as described in Powering on the optional 5U expansion enclosure.
