Diagnosing Problems

Your initial response to a system problem should be to:

  1. Check power connections.
  2. Observe the system's LEDs carefully.
  3. Check cable connections on the system modules.

If a problem is beyond the scope of this chapter, refer to Appendix C, Customer Support for further instructions.

Note: Running the show version and show hardware commands is often a good first step when trying to troubleshoot a problem.

Initialization Sequence

Each E-series line module is initialized independently. As a result, the CLI on the SRP module may become available before the line modules have completed initialization. Commands relating to a line module may fail if the module has not completed initialization. The show version command can be used to display line module status. Do not enter commands for a line module until its state is "online."
