Check the following if a problem appears on one of the PRE modules.
• Is the STATUS LED on the primary PRE green at the end of the boot sequence?
• If no, check the other LEDs on other modules in the chassis. If no other LEDs are on, check for a problem in the power
subsystem, as described in the "Troubleshooting the Power Subsystem" section in the Cisco uBR10012 Universal Broadband
Router Hardware Installation Guide .
• If no, and no other LEDs on the PRE are on but LEDs on other modules are on, remove the PRE from the slot, check for
any bent or broken pins on the backplane connectors, and reinsert it. Ensure that it makes solid contact with the backplane
and is securely locked in by firmly closing both locking levers.
If other LEDs on the PRE modules are on, check the Cisco uBR10012 Universal Broadband Router Troubleshooting Guide
for additional instructions.
• If no, but the FAIL LED is on (yellow), remove the PRE and reinsert it. If that fails, insert a new PRE. If that fails, contact
Cisco Technical Assistance for assistance.
• Repeat the above steps for the redundant PRE, except that its STATUS LED should remain OFF and its alphanumeric display
should read IOS STBY, if it is operating correctly.
• Verify the status of the internal Ethernet interface (ethernet0/0/0) of the PRE module, which is used for inter-module
communications. If this internal interface is down, it could indicate that the PRE module is not fully seated in its slot or that a
hardware failure has occurred.

Do not confuse the internal Ethernet interface ( ethernet0/0/0 ) of the PRE module with the external Fast Ethernet
interface ( fastethernet0/0/0 ) of the PRE module, which is used for network management and remote access.
Note
Alarm Temperature Ranges for the Cisco PRE5 Module
The facility-alarm critical exceed-action shutdown command allows you to enable or disable the auto-shutdown feature on the
Cisco uBR10012 router. When auto-shutdown is enabled, the router shuts down automatically when its core or intake temperature
exceeds the critical temperature threshold for 2 minutes.
