ALARM TROUBLESHOOTING
Summary: This section provides the user and maintenance personnel with a table of definitions
for all alarm messages that can be generated by the Cellworx STN system. Also provided are
suggestions for troubleshooting the alarms incurred during system operation.
A general knowledge of how the Cellworx STN functions and what alarm indications mean will
aid in troubleshooting tasks. The following assumptions are made by this procedure:
•
All Cellworx STNs in the network are properly equipped.
•
There may be a single cause for multiple alarms or trouble indications.
•
Only a single failure exists.
1. Accumulate the alarm information from the system to determine the highest level of
alarm, and which node is generating the alarm.
Reference: NTP-007.
2. Locate the retrieved alarm message in Table 4-1 and refer to the suggested course of
action provided. The alarms are listed alphabetically in bold and the actual TRAP
messages are listed below the alarm message.
