•Hardware Problem—The card might not be fully inserted into its slot, or the card hardware itself could have failed. In particular, if the problem began occurring after the card was moved or after a power outage, the card could have been damaged by static electricity or a power surge. Only a small number of fabric ping timeouts are caused by hardware failures, so check for the following before replacing the card:

–Reload the software on the line card, using the hw-module slot reset command.

–Remove and reinsert the line card in its slot.

–Try moving the card to another slot, if one is available.

If software-forced crashes continue, collect the following information and contact Cisco TAC:

•All relevant information about the problem that you have available, including any troubleshooting you have performed.

•Any console output that was generated at the time of the problem.

•Output of the show tech-supportcommand.

•Output of the show log command (or the log that was captured by your SYSLOG server, if available).

For information on contacting TAC and opening a case, see the “Obtaining Technical Assistance” section on page x.
