Figure B-2 Aruba 50 FE Port
The port accepts a 4- or 8-conductor Category 5 UTP FE cable with an RJ-45 male connector.
The FE port detects MDI/MDX and automatically adjusts for straight-through or crossover
cables. However, if Power Over Ethernet (POE) is used, a straight-through cable is required.
The maximum length for FE cables is 100 meters (325 feet).
When the Aruba 50 is installed in an air-handling space, as described in NEC (2002) Article
300.22(C), POE is required. Also, any FE cable installed in such spaces should be suitable
under NEC Article 800.50 and marked accordingly for use in plenums and air-handling spaces
with regard to smoke propagation, such as CL2-P, CL3-P, MPP or CMP.
Install cables in accordance with all applicable local regulations and practices.
