Error Code Description
B1xx 4694 System processor firmware failure
B1xx 4695 System power control network (SPCN) to
service processor interface failure
B1xx 4696 System firmware interface failure
B1xx 4698 Service processor firmware error
This is usually an indication that the interposer plug count has not been set after an MES
upgrade or FRU replacement of an MCM or L3 cache module. It can also indicate that the plug
count values were not revalidated after the primary I/O book was replaced. In both cases, it is
only an informational message.
If the managed server is down, go to the service processor error log and find the error log entry
containing B1xx 4698. Examine the first two bytes of word 13 of the detailed entry information.
If the managed server is running, look at the AIX error log entry containing B1xx 4698. This will
be a "SCAN_ERROR_CHRP" error with an identifier of BFE4C025. In the detail data, find the
string "B1xx 4698" (if present, it will be at byte 60 of the detail data). Go forward 8 bytes after the
"B1" to byte 68 and examine bytes 68 and 69.
If the value is E10B or E10C, do the following:
v If the primary I/O book was just replaced, go to the service processor menus and select
"System Information Menu," then select "MCM/L3 Interposer Plug Count Menu." At the 0>
prompt, enter 50 to commit the values and write them to the VPD. Fully exit the menu before
powering on the system.
v If an MCM or L3 cache module was just added or replaced, go to the service processor menu
and select "System Information Menu," then select "MCM/L3 Interposer Plug Count Menu."
Find the index number that corresponds to the module that was just added or replaced and
enter the new plug count that was included in the FRU or MES kit. If the plug count is not
included with the FRU, enter 7 as the new plug count (to account for the number of times the
module was plugged during the manufacturing process). Fully exit the menu before powering
on the system.
For all other values of bytes 68 and 69, or the first two bytes of word 13, do the following:
1. Check for system firmware updates.
2. Reset the service processor by activating the pinhole reset switch on the operator panel.
3. Call service support.
