2602 0010 Description: PCI probe error, bridge in freeze state
Action: If the location code identifies a slot, do the following:
1. Check for system firmware updates. Apply if 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. Is the system running Linux?
YES Go to

The System is Running Linux
″
on page 245.
NO Check the PCI Adapter Placement Reference to see if the adapter is hot-pluggable.
If it is not hot-pluggable, follow the procedure found in
″

″
on page 245 because the system must be powered off to continue. If the
adapter is hot-pluggable, go to step 4 below.
4. Use the hot plug service aid to reseat the card specified by the location code. See
“Replacing a Hot-Pluggable PCI Adapter” on page 453. If reseating the adapter fixes the
problem, go to MAP 410:

Attention: Before moving the adapter to another slot, verify with the customer or system
administrator that the slot that the adapter is being moved to is available to the partition in
which the adapter presently resides.
5. Is there an empty slot available into which the adapter could be plugged?
YES Use the hot plug task to move the adapter card to another slot behind a different
PCI bridge. The “System Logic Flow” on page 21 identifies the PCI bridges and the
associated slots. See “Hot-Pluggable PCI Adapter Removal” on page 450 when
removing the adapter, and “Installing a Hot-Pluggable PCI Adapter” on page 457
when installing the card in the new slot. If the card is successfully reconfigured in the
new slot (behind a different PCI bridge), the slot in which the card was originally
plugged is bad. Replace the PCI riser card or I/O planar in which the card was
installed, location: U0.1-P2 or U0.

successfully in the new slot, replace the adapter.
NO Replace the adapter. If replacing the adapter fixes the problem, go to MAP 410:

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 127.
