Managing Alarms

Alarms occur when an event or configuration change has taken place on the Expressway that requires some manual
administrator intervention, such as a restart. Alarms may also be raised for hardware and environmental issues such
as faulty disks and fans or high temperatures.

The Alarms page (Status > Alarms) provides a list of all the alarms currently in place on your system (and, where
applicable, their proposed resolution). When there are unacknowledged alarms in place on the Expressway, an alarm
icon appears at the top right of all pages. You can also access the Alarms page by clicking on the alarm icon.

Each alarm is identified by a 5-digit Alarm ID, shown in the rightmost column in the alarms list. The alarms are
grouped into categories as follows:
