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.
