Troubleshooting the Cisco PRE5 Module Installation
At system startup, the following sequence should appear on the primary PRE:
1. The FAIL LED should briefly come on (yellow) and go off, and the STATUS LED should start flashing (yellow).
A series of messages should appear on the PRE alphanumeric display, indicating the progress of the boot sequence.
2. On successful completion of the boot sequence, the message IOS RUN should appear on the alphanumeric display.
3. The STATUS LED should be on (green) to indicate that this is the primary PRE.
The sequence on the redundant PRE is similar, except that the STATUS LED remains OFF and the messages on the alphanumeric
display are slightly different. The final message upon a successful boot sequence should be IOS STBY to indicate that the PRE is in
the standby state.
