Alarm Message
What It Means
What to Do
A Low Battery
The UPS has shut down after running
on battery and discharging the
batteries.
Wait for AC input power to be restored. When AC input
power returns, the UPS begins recharging batteries and
applies power to the load.
C High Battery
The battery voltage is too high
because of a charger problem,
battery problem, or incorrect
parameter setting.
Contact your Avaya service representative.
E Low AC Output
The UPS has shut down because the
AC output voltage is too low to
provide power to the load.
Contact your Avaya service representative.
F High AC Output
The UPS has shut down because the
AC output voltage is too high.
Contact your Avaya service representative.
S High AC Input
The AC input voltage is too high; any
further increase to the voltage may
damage the UPS.
This alarm automatically clears when input voltage
returns to normal limits. The UPS will continue to support
the load until the batteries are depleted.
G Output Overload
The load is requiring more power
than the UPS power modules are
capable of supplying, and the UPS
has switched to Bypass mode.
Switch off your equipment one piece at a time until the
alarm stops.
I Overload Shutdown
The UPS has shut down due to
excessive load.
Remove excess load(s) from the UPS output and restart
the UPS by pressing the ON button through the front
panel display.
