Power Filter Units
Located at the bottom rear of the chassis are slots for two 165A Power Filter Unit (PFU) assemblies. Each PFU provides
DC power from the Central Office (CO) battery sub-system to the chassis and its associated cards. Each load-sharing
PFU operates independently of the other to ensure maximum power feed redundancy. The maximum input operating
voltage range of the PFU is -40 VDC to -60 VDC; the nominal rage is -48 VDC to -60 VDC.

Important:
In the event that the CO has AC power only, a separate rack mount AC to DC converter is required.
The following drawing shows the PFU and its connectors. Refer to the Cabling the Power Filter Units chapter for
information on installing and cabling the PF.
