• The fan should begin operating and should stay on while power is applied to the system.
• On some models, the DIAG LED should come on, stay on for the duration of the system’s
self-test diagnostics, and then turn off.
While booting, the console screen displays a script and system banner, which should be similar to
the following:

If problems occur, try to isolate the problem to a specific subsystem. The Catalyst 3000 series LAN
switches have the following subsystems:
• Power subsystem—This subsystem includes the input power, AC power cable, and power supply.
• Cooling subsystem—This subsystem includes the fans, which should be operating when the
system power is on.
• Network interfaces and system cables subsystem—This subsystem includes all the network
interfaces and the cables that connect the equipment to the network.
