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 (+6%, -10% @ ambient temperature)
volts at frequencies of 50/60 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.
