Troubleshooting PowerOn Auto Provisioning

Switch Does Not Come Up in Time for POAP to Complete

If the switch does not come up in a reasonable duration for POAP to complete, connect to the switch through the serial line and check to see if it is stuck at the following prompt: 

Waiting for system online status before starting POAP ...
Waiting for system online status before starting POAP ...
Waiting for system online status before starting POAP ...

System is not fully online. Skip POAP? (yes/no)[n]:

You can continue with POAP by entering no at the prompt. If POAP does not start properly on the second attempt, proceed with the normal setup by entering yes at the prompt when it returns.
