Diagnostics and Troubleshooting

Troubleshooting

The status of each card in the Hotwire DSL chassis is indicated on the Card

Selection screen (see Chapter 2, Hotwire Menus and Screens). Choose Card

Selection from the Hotwire Chassis Main Menu.

Checking Alarms

If the Card Selection screen indicates that a Major or Minor Alarm is on a card, follow the menu 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. You should go to the MCC’s Monitor → Card Status → Syslog (A-A-C) and view the event on its system log. See SYSLOG Messages on page 5-9.

Major Alarms

Use Table 5-3 to determine the appropriate action to take for each Major Alarm.

Table 5-3. Major Alarms (1 of 2)

		– If the results are normal, the problem was transient. Log the
		results.
		– If the results are the same as the first selftest, the card should be
		replaced. If only one port on a DSL card is bad, that port can be
		disabled. You may continue to use the card until it is convenient to
		replace it.
