Troubleshooting Alarm Messages

If the GoQAM displays an alarm condition, fails a self-test, or does not work

properly, refer to the table in this section to find and correct the cause. Some alarm

conditions may require you to contact Cisco. See

Customer Information

(on page

147) for contact information.

Important!

The RF alarms listed in this section apply only to the RF GoQAM. RF

alarms do

not

occur on the IF GoQAM.

See

Troubleshooting Boot Screen Error Messages

(on page 143) for resolving

problems encountered during the start-up process.

Front Panel LCD Alarm Messages

The following table lists Alarm Messages displayed on the front panel LCD of the

GoQAM, the default level of severity defined for the GoQAM, a probable cause for

the alarm, and suggestions for correcting the alarm condition.

Notes:



The LCD descriptions for each alarm are arranged in alphabetical order.



Alarm messages that occur for the two outputs (RF or IF) or the four ASI input

ports are listed only once. The numbers in parentheses indicate the range of port

numbers that might be affected by the alarm.

Example:

The “Input (1-4) errored MPEG packet” description corresponds to the

Input port that is affected.
