2.7 Power Modules Removal/Replacement

The Power Supply Modules in the FRM220 are available in two versions, one AC and one DC type. The

universal AC version supports input voltages of 100 to 240 (±10% @ ambient temperature) volts at frequencies of

47 to 63 Hertz. The DC version supports either a standard 36 to 60VDC input voltage. Only one power supply

module is required to power a completely full rack. When two Power Supply Modules are installed, the supplies are

hot swappable and redundant, meaning any one supply may be removed and replaced without impacting the

operation of the FRM220 Rack.
