Indoor connections
The CAT5e cable that connects the PoE power supply to the network equipment must
meet the following requirements:
• Screening: Must be either foil screen (FTP) or braided screen (STP) cable.
• Connectors: Must use screened RJ45 connectors with metal shells at both ends.
• Electrical connection: There must be a continuous electrical connection
between both screened connectors.
CAUTION
The connected network equipment must feature screened RJ45
connectors and must be connected to ground, otherwise the PoE power
supply will not be grounded, and this may increase the levels of unwanted
radiation from the ODU - PoE power supply cables.
Cable grounding kits
Drop cables must be grounded at the points specified in Grounding and lightning
protection on page 2-11. One
cable grounding kit (Figure 1-8) is required for each
drop cable grounding point.
