Diagnostics and Troubleshooting

Troubleshooting

The status of each card in the Hotwire DSLAM is indicated on the Card Selection screen (see Components of a Hotwire Screen in Chapter 2, Hotwire Menus and Screens).

Checking Alarms

If the Card Selection screen indicates that a Major or Minor Alarm is on a card, follow the menu selection sequence Diagnostics → Alarms (D-B) to determine the cause of the alarm.

No Response at Startup

DSL cards do not respond at startup after rebooting chassis. Reset the MCC card. Be sure LEDs go through the reset sequence twice within about one minute.

If a DSL card does not appear on the Card Selection screen because the MCC card can no longer communicate with it, the MCC card will generate a major alarm. Follow the MCC's menu selection sequence Monitor → Card Status → Syslog (B-A-C) and view the event on the MCC Card System Log.

Major Alarms

Use Table 6-2 to determine the appropriate action to take for each Major Alarm.

±If the results are normal, the problem was transient. Log the results.
