CAUTION
If the ODU and lightening arrestor are not
connected to the IFL, do not power on the
IDU chassis without first making sure the
IFL is not connected to the IDU chassis.
Failure to observe this instruction could
result in damage to the equipment.
To connect power cables from the dc power source (usually a
rectifier) to the dc power supply, follow the steps below.
1. Measure the voltage level of the power source to verify it
can accommodate the total IDU and ODU power
requirements.
(The IDU supplies power to the ODU through the IFL.)
If the voltage level cannot accommodate the IDU and ODU,
the power source must be upgraded before you can proceed.
2. Remove power from the power circuit.
3. Loosen the two Phillips screws from the square terminal
block cover plate on the front of the power supply.
