The Ethernet cable must be of Category 5e (enhanced) or higher. In addition, its cross-
sectional area must be 24 AWG or larger and frame spread rating must be CM or higher.
The Ethernet cables can be straight-through cables or crossover cables.
With the internal PoE module providing power, the maximum length of an Ethernet
cable is 100 m. With the Extender, the distance of the pRRU3901 and RHUB can be
extended by the Extender up to a total distance of 200 m.
Ethernet cables are not delivered, and they must be prepared onsite. You need to use a
