FRM220-DC48 power unit is a power supply that installs in an FRM220-CH20 chassis. It automatically detects input power  and provides continuous regulated power for the chassis.

One single power supply unit can support a fully loaded 19 media converter chassis and the NMC management card. AC and DC power supply units can be installed together in an FRM220-CH20 fiber chassis.

Accepted power input for the FRM220-DC48 unit is negative 36-72V DC.

Power units are redundant and hot swappable in the FRM220-CH20 chassis, assuring smooth operation of chassis and equipment even in the event of a power unit failure.
