A device backplane might be failing.
If you need additional information for failing part numbers, location codes, or removal and replacement procedures, see Part locations and location codes. Select your machine type and model number to find additional location codes, part numbers, or replacement procedures for your system.
Complete the following steps:
- 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 table at the end of this procedure 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.
- 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 midplane of the 5886 disk expansion unit. See the table at the end of this procedure for location and part number information.
- 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.
- Does the SRC that sent you here begin with a 50AD or are you working
with an attached 5724 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.
- Does the SRC that sent you here begin with a 50B1 or are you working
with an attached 5887 disk expansion unit?
- No: Continue with the next step.
- Yes: Replace the midplane of the 5887 disk expansion unit. See the table at the end of this procedure for location and part number information.
- Does the SRC that sent you here begin with a
57C3 or are you working with an attached EDR1 PCIe storage enclosure?
- No: Continue with the next step.
- Yes: Replace the midplane of the EDR1 PCIe storage enclosure. See the table at the end of this procedure for location and part number information.
- Replace the device backplane. See the following table for location
and part number information.
