application without risking adverse impact to your production SAN.
Use any of the following commands to set SNMP traps:
Note
You do not have to physically remove the fan or power supply, nor do you have to physically increase
the temperature, to generate these traps.
Troubleshooting Startup Issues
LEDs indicate all system states in the startup sequence. By checking the LEDs, you can determine when

supervisor module if you have trouble with the system software. Status LEDs on the supervisor

If you have a redundant supervisor module, refer to the following website for the latest Cisco MDS
9000 Family configuration guides for descriptions of how the redundant supervisor module comes
online and how the software images are handled:

Switching module—Status LEDs on each module indicate if it has been initialized by the supervisor
module. A module that is partially installed in the backplane can cause the system to halt.
