LED Position or Color Meaning
Green All diagnostic tests have passed and the module is operational.

modules, this LED turns red immediately after the system is
powered on, until the software boot process begins.
Off The module is disabled or is not powered up.
Meaning
AC input voltage is between 70V and 85V.
AC input voltage is less than 70V or the power supply
is turned off.
AC input voltage is between 70V and 85V.
55 VDC power supply output, and power supplies
are operating within regulation limits.
Indicates that it is a redundant power supply module
Blinks on for 0.5 seconds and off for 0.5 seconds,
continuously, to signal that 55VDC power supply
output is asserted and that the power supplies are
operating within regulation limits.
The DC output voltages have not exceeded the alarm
threshold ranges
Indicates that an output voltage is out of the specified
range, or that a fan has failed, as sensed by lack of
fan rotation.
Identifies the power supply module receiving the
beacon signal.
On state is indicated by blinking on for 0.5 seconds
and off for 0.5 seconds.
