6.0 Troubleshooting

The following section is used to help determine the root cause of problems and offer a way to fix them.
6.1

Alarm/Event Conditions

The radio contains an alarm and event log to assist in the monitoring and troubleshooting day to day
operation. An alarm is an event that affects performance and requires action. Typically, alarms are
noticed due to the PWR LED blinking. Noted below, some alarms can be corrected by the user (noted
with an asterisk (*)) while others may require returning the unit to GE MDS for diagnostics.
Many alarms and events also have an SNMP trap associated to them for use in applications using SNMP.
For more information on the Alarm and Event Log, see Event Log Menu.
