Power Supply
The power supply contains a power status LED. The LED lit green indicates power input; red indicates that
input/output failed or there is a power fault. If the power status LED is off, it indicates there is no AC/DC
input. Check the AC/DC power source and ensure the power supply is fully seated.
Units with DC power, there are two LEDs: Power and Alarm. When the Power LED is lit green, it indicates
the power supply is functioning correctly. If the Power LED is lit, the Alarm LED will be unlit.When the
Alarm LED is lit red, it indicates that input/output failed or there is a power fault. If the Alarm LED is lit, the
Power (LED) will be unlit.
Alarms
Alarms help you identify where a specific problem is occurring with the Call Relay SP unit. Through the
Alarm Manager, you can read a description of the problem, and isolate where the problem is occurring. Verify
all severity 1 alarms first; these alarms indicate that the unit is in critical condition and the entire system is
affected.
You are able to review alarms via Command Line Interface (CLI). See Chapter 5: System Alarms for specific
information about obtaining and reading alarms.
