Troubleshooting PREs
• Check the LEDs on the PRE faceplate to make sure it has powered up properly. If necessary, remove
and reinsert both PRE modules to power them up again. Also, make sure the terminal equipment is
working properly.
If the cable, connections, power, and terminal settings all check out and you still cannot connect to the
console port on the module, replace the module in question. If the problem persists, contact the Cisco
TAC for further assistance.
