Diagnostics and Troubleshooting Overview

Several features are available to assist you in evaluating the Hotwire DSL Router. The following sections are covered in this chapter:

Device Restart

Alarms Inquiry

System Log on page 6-2

Ping on page 6-5

TraceRoute on page 6-7

Device Restart

The DSL router can be restarted locally or remotely. From the CLI, type Restart and press Enter.

The router reinitializes itself, performing a power-on self-test and resetting the local System Log (SYSLOG).

Alarms Inquiry

The DSL router’s front panel includes an Alarm (ALM) LED to alert you to alarm conditions. The alarm(s) detected can be viewed using the show alarms CLI command.

See show alarms on page A-24 in Appendix A, Command Line Interface, for information about the command and what is displayed when the command is entered.
