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.
