4.3 Ethernet Cabling – Copper Interface

For the copper interface, data cabling from the Horizon Compact Plus unit to the PonE Power

Injector/Lightning Arrestor consists of outdoor rated, shielded, CAT5E cables equivalent to Belden 7919A.

The shielded cables require shielded RJ45 connectors. Use of standard indoor unshielded RJ45

connectors may result in a lack of lightning protection, poorly constructed cables, intermittent connections

and data loss. Depending on the system configuration ordered and fielded, up to four shielded RJ45 and

two unshielded RJ45 connectors are provided.

The cables terminate in a DWI Power on Ethernet (PonE) Power Injector/Lightning Arrestor unit located

either outside of the building cable entry point (using the outdoor PonE unit) or inside the network

equipment building (using the indoor PonE unit).

DO NOT CONNECT SHIELDED RJ45 CONNECTORS TO ETHERNET CABLES CONNECTING THE

LIGHTNING ARRESTOR TO THE NETWORK SWITCH.

Note: Straight through Ethernet cables must be used between the PonE power injector and the

Horizon Compact Plus. The use of a cross-over type, or incorrectly wired CAT5E cables, will

cause the PonE power injector to go into an alarm condition and not power up the Horizon

Compact Plus. A Status LED indicates the status of the PonE power injector (see Section 5.1.4)

The PonE unit contains Lightning Arrestors and must be grounded according to local or regional Electrical

Codes. Unshielded Ethernet cables are connected between the PonE unit and the Ethernet switch or

router. Power for the PonE unit is supplied by 2-wire 16 AWG electrical wiring, carrying 48 V DC (-48 V

or +48 V) with a maximum current draw of 2 amperes.

If Port 2 is not being used, ensure that a protective weatherproof cap is fitted to the port receptacle.

4.3.1 Using Outdoor PonE Unit

Figure 4-8 Outdoor Unit PonE and RJ45 Connections

DO NOT coil excess Ethernet cable, but fold in a zig-zag fashion whilst

observing a minimum bend radius of 2 inches. The effect of lightning induced

current surges in the tower or conductors adjacent to the Ethernet cable will be

minimized when the Ethernet cable is folded in this way.
