Chapter 3 Troubleshooting PRE-1 Modules
PRE-1 Module Faults
•Verify that both PRE-1 modules are booting the same version of Cisco IOS software. Slight variations in the loading of different images could allow the slot B PRE-1 module to boot first.
PRE-1 Module Faults
The PRE-1 module provides the IP routing and forwarding functionality in the Cisco uBR10012 router. Thus, in a non-redundant PRE-1 configuration, a PRE-1 failure is a system failure. A redundant PRE-1 configuration is recommended because it allows the redundant PRE-1 module to automatically assume full functionality upon failure of the primary PRE-1 module.
If the PRE-1 module fails, the yellow PRE-1 STATUS LED lights. If this occurs, try the following steps:
•Reboot the Cisco uBR10012 router
•Move the PRE-1 module to the other PRE-1 module slot
•Replace the PRE-1 module with a spare module
In addition, you should capture any error messages that appear on the console, as well as the state of the PRE-1 LEDs and alphanumeric display. Then contact the Cisco Technical Assistance Center (TAC).
Figure 3-1describes the LED indicators on the PRE-1 faceplate. Use these descriptions to verify the operation of the PRE-1 module.
