Troubleshooting Backplane Modules

System Messages and Fan Problems

Look for system messages reporting a temperature problem or problem with the fans. Individual messages may suggest different solutions. Connect a terminal to the console port, and look for any of the following system messages:

C4K_CHASSIS-2-INSUFFICIENTFANSDETECTED

C4K_CHASSIS-2-INSUFFICIENTFANSSHUTDOWN

C4K_IOSMODPORTMAN-4-CRITICALTEMP

C4K_IOSMODPORTMAN-4-FANTRAYBAD

C4K_IOSMODPORTMAN-4-FANTRAYPARTIALFAILURE

C4K_IOSMODPORTMAN-4-FANTRAYREMOVED

C4K_SUPERVISOR-3-FANTRAYREADFAILED

C4K_SUPERVISOR-3-FANTRAYSEEPROMREADFAILED

C4K_SUPERVISOR-3-FANTRAYSEEPROMINVALID

C4K_IOSMODPORTMAN-4-TEMPHIGH

C4K_IOSMODPORTMAN-4-TEMPUNDERCRITICAL

C4K_CHASSIS-2-OVERHEATINGSHUTDOWN

If you see any of these messages or other messages related to fans, go to the following location and enter the message text to find recommendations for your situation.

Useful CLI Commands

The show environment status fantray command can give additional information useful in diagnosing fan tray problems.

Troubleshooting Backplane Modules

The Cisco Catalyst 4500 E-series redundancy scheme uses removable redundancy modules (also called mux-buffers), on the passive backplane to switch traffic to the active supervisor engine. There is one redundancy module per switching module. Redundancy modules and a redundant clock ship standard with every Cisco Catalyst 4507R-E and 4510R-E chassis. Spare redundancy modules (WS-X4590-E=) and a clock module (WS-X4K-CLOCK-E=) are available for serviceability.

The following conditions indicate that you may need to replace the redundancy modules and clock module:

The switch powers down and stays down for a few minutes to a few days for no clear reason.

The output-fail LED on the power supplies are red and no power is delivered to the chassis. The other LEDs on the power supply are green.

The Status LEDs on the switching modules and the supervisor engine are flashing green.

CPU Utilization LEDs are flashing green or off.
