Chapter 5: Troubleshooting

After powering on the switches of a stack and waiting two to three minutes

for the stack to complete the discovery process, you observe that the

Stack MSTR LED on the front panel of all the switches is off. This could

indicate that the discovery process encountered a problem that prevented

the stack from selecting a master switch. For suggestions on resolving the

problem, refer to "Troubleshooting the Discovery Process" on page 71.
