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-amp lines can be used. For
additional information on power requirements, see the Technical Specifications chapter.

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.
