When the system boot is complete, the supervisor engine module should initialize the switching
modules. The status LED on each switching module goes on when initialization has been completed, and
the console screen displays a script and system banner similar to the following:

If problems occur, try to isolate the problem to a specific subsystem. The Catalyst 5000 series LAN
switches have the following subsystems:
Power subsystem —This subsystem includes the power supplies and power supply fans.
Cooling subsystem —This subsystem includes the chassis fan assembly, which should be operating
when the system power is on.
Processor and interface subsystem —This subsystem includes the supervisor engine module
(which contains the system operating software), the network interfaces, and all associated cabling.
