Cisco uBR10012 Universal Broadband Router Hardware Troubleshooting Guide for Cisco IOS Release 12.2SC

Basic Troubleshooting Tasks and Startup Issues

This section describes the basic procedures that users should perform before undertaking a detailed troubleshooting analysis of the Cisco uBR10012 router or logging a case with the Cisco Technical Assistance Center (TAC).

These basic troubleshooting checks are organized as follows:

•Basic Troubleshooting Checklist

•Displaying the Cisco IOS Software Version

•Displaying System Environment Information

•Hardware Troubleshooting Flowchart

•Cisco uBR10012 System Startup Sequence

Basic Troubleshooting Checklist

If you encounter a problem after you install the Cisco uBR10012 router, go through the following troubleshooting checklist to check for the most common error conditions before you contact the Cisco Technical Assistance Center (TAC) or before you perform a detailed troubleshooting analysis:

1. Is the power on?

2. Is each Power Entry Module (PEM) securely inserted into the router? Is each PEM connected to a power source that is supplying voltage in the proper AC or DC range? Are all power leads and cables firmly connected at both ends?

3. Is the fan assembly module installed in the chassis and operating? Can you hear the fans operating, and when you put your hand in front of the fan blowers, can you feel the air flow? Are all empty slots covered with blank front panels, to ensure the correct air flow through the chassis for cooling?

4. Is each Performance Routing Engine (PRE) module firmly seated and securely inserted in the chassis?

5. Is at least one Timing, Communication and Control Plus (TCC+) card installed in the router?

6. Are the other line cards firmly seated and securely screwed to the chassis?

7. Are all data cables firmly connected at both ends?

8. Are the ports properly configured?

After going through this checklist, go through the remaining sections in this chapter to verify the installation and to perform basic troubleshooting.

Displaying the Cisco IOS Software Version

Use the show version command to confirm that the router is running the proper version of Cisco IOS software and has a sufficient amount of system memory. The command also reports the system uptime and the method by which the system was powered up.

In the following sample of output from the show version command, some of the information that may be useful for troubleshooting appears in bold type:

Displaying System Environment Information

Use the show environment command to display the basic system environment status, to verify the following:

•Make sure that the system operating temperature is always between 41

degrees 

degrees

 degrees

•That the fan assembly module is installed in the chassis and operating properly.

•Report that the operational status of the PEMs and blower is OK.

If the operating temperature is not between 41

degrees

degrees

The following example is sample output from the show environment command for a system with PRE4 and two DC PEMs and installed:
