Power supply location considerations
Find a location for the power supply that meets the following requirements:
l
The power supply is rated for indoor use and can be mounted on a wall or other flat surface.
l
The power supply must be kept dry, with no possibility of condensation, flooding, or rising
dampness.
l
The power supply can be accessed to view status indicators.
l
The power supply can be connected to the ePMP module drop cable and network terminating
equipment.
l
The power supply can be connected to a mains or DC power supply that meets the requirements
defined in Table 16.
Ethernet cabling
For more information on the Ethernet cabling components of an ePMP installation, see:

Outdoor Cat5e cable
Ethernet standards and cable lengths
All configurations require a copper Ethernet connection from the power supply port to the power supply
and network terminating equipment.
Attention
All cables used for outdoor installations must be suitable to be used for that
environment and rated accordingly.
For each power supply, the maximum permitted drop cable length is specified in Table 17.
Table 17: Power supply drop cable length restrictions
Part number Description Maximum cable length (*1)
N000000L034 Power Supply for Radio with Gigabit Ethernet (no cord) 330 feet (100m)
(*1) The maximum length of Ethernet cable from the device to the network device needs to follow 802.3
standards. If the power supply is not the network device the cable from the power supply to the network
device must be included in the total maximum cable length.

Cambium Industrial Cable
Cambium Industrial Cable uses 24-gauge solid bare copper conductors, covered by bonded-pair polymer
insulation. The conductors are protected by double-layer shielding consisting of a solid foil layer under
the braided tinned copper mesh, providing excellent shielding while maximizing flexibility. The cable is
jacketed by industrial-grade UV-resistant, abrasion-resistant, and oil-resistant PVC.
