Status Indicators and Alarms
The status of the Hybrid Ultra is indicated on the front display panel module
on units equipped with an ICM, or via the network GUI (see Section 4) on
remotely monitored units. It is also available through SNMP (see Section
4.8.2). Green "POWER" and red "FAULT" LEDs on the Power Modules,
along with the form-C alarm contacts on the rear panel indicate the core
status of unit.
There is an option on the Setup & Control tab in the GUI for most alarms to
send an e-mail to designated addresses for remote notification (see Section
4.8.3).
All alarms and warnings will be displayed on the front display screen on
Hybrid Ultra systems and entered in the Alarm History log (most recent 20
alarms listed) (see Section 3.2.6).
Most alarms reset automatically when the trigger condition is removed.
Major alarms such as a Module DC Output Failure or Module Configuration
Error require that the module be temporarily removed to cycle input power
and clear the fault.
