Error Code Description Action/
Possible Failing FRU
1023 BF06 Unable to resolve the chassis VPD in an I/O
subsystem
The chassis VPD in the I/O subsystem drawer
identified by the location code could not be
resolved. This may be an indication that more
than one FRU in the drawer was replaced during
a service action. If this is the case, reinstall the
original FRUs in the drawer, then replace the
FRUs one at a time.
If only one FRU was replaced and this error
code occurred, call service support.
1023 CD96 A power short has been detected in the DASD
subsystem in an I/O drawer.

1023 F516 An N+1 boundary (DCA or fan) has dropped to
N-mode status in the fourth subsystem (with IBF,
location: U2.9.
This is normally an informational message. It
should be accompanied by other error codes
that more precisely indicate where the failure is.
Examine the service processor error log. If there
are no other power-related error codes (in the
time frame in which this code was generated) in
the service processor error log, the FRU
indicated with this error code, if any, should be
replaced.
