Step 4 Determine whether the airflow is restricted or if the ambient temperature in the
room is too warm.
Step 5 Determine whether the power supply is functioning properly. See the
“Troubleshooting the Power Supply” section on page 5-6.
Step 6 Verify that the fan assembly is properly seated in the backplane by loosening the
captive installation screws, removing the fan assembly, and reinstalling it.
Step 7 Restart the system.
Step 8 Verify that all fans are operating. You should hear the fans at system start.
Step 9 If the system is still detecting a fan assembly failure, contact the Cisco TAC for
assistance.
Troubleshooting Backplane Modules
The Cisco Catalyst 4500 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 and 4510R chassis. Spare redundancy modules
(C4K-MUX=) and a clock module (C4K-CLOCK=) are available for
serviceability.
The following conditions indicate that you may need to replace the redundancy
modules and clock module:
