Power Filter Units (Pfus) - Cisco ASR 5500 Installation Manual

▀ Chassis

Power Filter Units (PFUs)

Two PFUs mount at the top front of the chassis. Each PFU supports four power planes.
A total of eight -48 VDC, 80-amp power feeds are required for a full chassis. The eight feeds operate in a 4+4 redundant
configuration. In lab environments where power redundancy is not required, four 80 A lines can be used.
Cable Management System
The ASR 5500 cable management system consists of two components. The first is a tray that mounts at the rear of the
chassis immediately below the card cage. The second is a cable management bracket that mounts to the front panel of
each Management Input/Output (MIO) or Management Input/Output Universal (UMIO) card.
Network cables are fed from either side or both sides of the tray and are then routed to the MIO/UMIO ports. The cables
are secured to the cable management brackets on the MIO/UMIOs via cable ties or hook-and-loop straps, and within the
cable management tray via hook-and-loop straps.
