If the location code identifies a slot:
1. Check the cabling to the adapter (in
particular, the adapters that have serial
ports). Serial ports may require null
modems or special cabling configurations
to avoid connecting driver outputs
together. This may create a PCI slot
power problem and force the adapter to
be deconfigured.
2. Move adapter to another slot (behind a
different PCI bus).
3. Check for available firmware updates for
adapter. Apply update if available.
4. Replace adapter.
5. Check for system firmware updates. Apply
if update available.
6. Replace I/O subsystem backplane (See
notes on Chapter 5, "Error Code to FRU
Index", on page 345).
If the location code identifies an I/O
subsystem backplane:
1. Check for system firmware updates. Apply
if update is available.
2. Replace I/O subsystem backplane.
The problem is associated with bridge "y" in
I/O subsystem "x". Replace the I/O board
associated with x
x = I/O subsystem
1=0

See "Determining Location Code" on
page 347 or location code information related
to this error.
1. Replace the part identified by the location
code associated with this error code.
2. If the location code associated with this
error code identifies an adapter, and
replacing the adapter does not correct the
problem, replace the I/O subsystem
backplane.
