Error Code Description
2602 0010 PCI probe error, bridge in freeze state
If the location code identifies a slot or PCI adapter:
1. Check for system firmware updates. Apply if update available.
2. 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.
3. Use the hot plug service aid to reseat the adapter specified by the location code. See
"Removing and Replacing a Hot-Pluggable PCI Adapter" on page 904. If reseating the
adapter fixes the problem, go to "MAP 0410: Repair Checkout" in the RS/6000 and
Eserver pSeries Diagnostic Information for Multiple Bus Systems manual. If the problem
is not resolved, continue with 4.
4. Use the hot plug task to move the adapter to another slot (behind a different PCI bridge).
The "I/O Subsystem PCI and PCI-X PHB and PCI and PCI-X Slot Locations" on page 30
identifies the PCI bridges and the associated slots. See "Removing and Replacing a
Hot-Pluggable PCI Adapter" on page 904 when removing the adapter, and "Installing a
New Hot-Pluggable PCI Adapter" on page 906 when installing the adapter in the new slot.
If the adapter is successfully reconfigured in the new slot (behind a different PCI bridge),
the slot in which the adapter was originally plugged is bad. Replace the I/O backplane
assembly that contains the slot in which the adapter was originally installed, location:
Ux.y-Pz.
If the adapter does not reconfigure successfully in the new slot, replace the adapter.
5. Go to "MAP 1542: I/O Problem Isolation" on page 306.
If the location code does not identify a slot or PCI adapter or no location code is specified,
go to "MAP 1542: I/O Problem Isolation" on page 306.
2602 0011 PCI probe error, bridge is not usable
Action/
Possible Failing FRU
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 391.)
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.
