SYSBKPL

The failing component is the system backplane (I/O backplane for 9406-MMA or 9117-MMA).

Use the table below to find the service information for the specified FRU.

Note: After you have replaced the part, make sure to set the enclosure serial number before powering up, otherwise the machine will not IPL. For more information, see "Setting the system enclosure type" in the operations guide for the server.

If the server is a multiple-drawer 9406-MMA or 9117-MMA server and the SRC is a B1xx SRC, use the last byte in word 3 of the primary SRC to determine which backplane to replace:

If the last byte is a 10, then replace the primary unit, I/O backplane.

If the last byte is a 20, then replace the secondary unit 1, I/O backplane.

If you don't have access to word 3 of the primary SRC, you can also determine which backplane to replace by using either of the following methods:

If you have access to the Advanced System Management Interface (ASMI), log on and display the details of the service processor error log. Using the Platform Event Log id (shown in the first table of each detail of the log), look at the first byte.

If the first byte is a 50, then replace the primary unit I/O backplane.
If the first byte is a 51, then replace the secondary unit 1 I/O backplane.

If you have access to a Hardware Management Console (HMC), log in as PE user and bring up Manage Serviceable Events under the Service Focal Point screen. Display the events for the corresponding service processor system, then double-click the system to see the details. Look at the Field Platform log ID, which contains a decimal value that you need to convert to a hexadecimal value.

If the first byte is a 50, then replace the primary unit I/O backplane.
If the first byte is a 51, then replace the secondary unit 1 I/O backplane.

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
	8204-E8A	10N9369	System backplane	Un-P1
	9406-MMA, 9117-MMA	42R7352	I/O backplane	Un-P1

This ends the procedure.
