Problem 1: The SYSTEM LED on the media converter is off.
Solutions: The unit is not receiving power. Try the following:

Verify that the power cord is securely connected to the power
source and to the DC connector of the media converter.

Verify that the power outlet has power by connecting another
device to it.

Try using another power source.

Verify that the DC voltage from the power source is within the
required levels for the AT-IMC2000/200 series media converter.
Solution: An internal component on the unit is damaged or not working
properly. Try the following:

Power cycling the unit.

If power cycling does not clear the fault, return the unit to Allied
Telesis.
Problem 2: The SYSTEM LED on the media converter is blinking slowly.
Solution: An error is present on the unit. Try the following:

Power cycling the unit.
If it is an AT-IMC2000TP/SP or AT-IMC2000T/SP unit, a transmit fault may
be occurring on the SFP module, or the SFP module itself may be causing
some other errors. The media converter will try to clear this error, but if the
error persists, try the following:

Remove and re-seat the SFP module.

Try a different SFP module.

Verify the SFP module is the correct type for your application.
