LED Indicators Description

(when unit is

connected to an

external power

source)

Green All batteries are fully charged.

Green, blinking At least one battery is charging.

Yellow, blinking At least one module would be using

more power than what is available

from batteries. Do not disconnect AC

power while this module is in use.

A blinking yellow LED takes

precedence over a blinking green one,

so when AC power is connected, even

if the LED is blinking yellow, batteries

are probably charging (depending on

conditions).

Red Battery error. Contact EXFO.

Red, blinking The detected temperature is too high.

This could lead to a thermal shutdown

of the unit if no action is taken to

reduce the temperature.

Off No battery present in the unit.

(when unit is not

connected to an

external power

source)

Off The global level of the batteries is

above the “low-battery threshold”.

Yellow The global level of batteries is low.

Red Battery error. Contact EXFO.

Red, blinking The detected temperature is too high.

This could lead to a thermal shutdown

of the unit if no action is taken to

reduce the temperature.
