DEVBPLN

A device backplane might be failing.

Perform the following:

  1. Does the SRC that sent you here begin with 506x, or are you working with an attached 5786 or 5787 disk expansion unit?
    • No: Continue with the next step.
    • Yes: Replace the SCSI interface card of the 5786, 5787 Disk Expansion Unit. See the following table for location and part number information. If this does not fix the problem, continue replacing the other failing items in the failing item list. If the other failing items do not fix the problem, replace the disk expansion unit chassis.
  2. Does the SRC that sent you here begin with a 509A or are you working with an attached 5886 disk expansion unit?
    • No: Continue with the next step.
    • Yes: Replace the mid-plane of the 5886 Disk Expansion Unit. See the following table for location and part number information.
  3. Does the SRC that sent you here begin with a 509D or are you working with an attached 5720 or 7214-1U2 expansion unit?
    • No: Continue with the next step.
    • Yes: This failing item is not applicable. Continue with the next item in the failing item list.
  4. Replace the device backplane, See the following table for location and part number information. CCIN or FFC Type and model Part number Description Location code 5786, 5787 Device backplane Un-P2 5886 42R7898 5886 SAS expansion unit midplane Un-P1 293D 9406-MMA, 9117-MMA 10N8968 Removable media enclosure assembly (includes the media backplane Un-P4

    5. Use the following table to determine the part number for the field replaceable unit (FRU):

    CCIN or FFC Type and model Part number Description Location code
