Your initial response to a system problem should be to:
- Check power connections.
- Observe the system's LEDs carefully.
- 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.
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."
