Appendix B Ethernet Cables and
Connectors
There will be several Ethernet cables used in installing the EUM3006:
• EUM3006 Cable: The 25 feet Ethernet cable that is attached to the EUM3006, which
is plugged into the DATA & PWR port of the PoE Injector.
• Cross-over Cable: The Ethernet cable from the DATA port of the PoE Injector to the
end-user’s PC must be a cross-over cable. A cross over cable has one end wired
according to T568A and the other end according to T568B. Both ends have RJ45
connectors.
• Straight-Through Cable: Straight-through Ethernet cables have both ends wired
according to T568A with RJ45 connectors. Straight-through cables can be used in a
number of locations:
• If a PoE lightning arrestor is used in the installation, then the cable between
the lightning arrestor and PoE injector must be straight-through.
• If the 25 foot cable with the EUM3006 is not long enough, another straight-
through Ethernet cable can be used to provide extended distances.
• If the EUM3006 is to be connected to a router or Ethernet Switch that do not
provide PoE, then a straight-through Ethernet cable is used to connect the
router or switch to the PoE injector.
• If a router or Ethernet switch are used, then they are connected to the end-
user’s PC by a straight-through Ethernet cable.
The Ethernet cables used between the PoE Injector and the EUM3006 must have all 4 pairs
wired as shown in Table 6.
