Power On Ethernet; On E) - DragonWave Horizon COMPACT Plus Product Manual

8.1 Power on Ethernet (PonE)
The copper interface variant of Horizon operates on -48 VDC and employs a proprietary Power on
Ethernet solution. The Horizon Outdoor and Indoor Power on Ethernet Lightning Arrestor units provide
integration of -48 VDC and data signals on the straight through Ethernet data cable. Power is not
integrated onto the optional out-of-band management Ethernet cable.
Note: The Horizon PonE implementation is proprietary and does not follow IEEE standards.
The Lightning Arrestor uses RJ45 connectors for the Ethernet cables and screw-terminals for the -48
VDC power connections. Dual -48 VDC power connectors are provided, allowing for the connection of
redundant power supplies.
The Lightning Arrestor unit contains protection against cable transients and power surges caused by
lightning or other sources. The Lightning Arrestor is installed at the opposite end of the CAT5E/PonE
cables to that of the Horizon unit and protects the network.
To ensure adequate lightning protection, the PonE Lightning Arrestor unit must be properly
grounded.
Horizon consumes a nominal 20 Watts (standard power), or 40 Watts (high power variant) from the -48
VDC supply. All eight of the wires in the Ethernet cable are used to carry power to the Horizon Compact
Plus unit. The Power on Ethernet Lightning Arrestor unit is rated at 2 amps.
The PonE unit has a protection feature that prevents power from being supplied to the Horizon Compact
Plus if it detects any under or over voltage/current conditions (see Section 5.1.4). Over or under
voltage/current conditions can occur if cables are incorrectly terminated.
Horizon Compact Plus Release 1.0.1
CAUTION
For Release 1.1 and earlier, serious damage to network switches
or routers can occur if the network is plugged into the connectors
marked "TO HORIZON UNPROTECTED". Power is fed to the
Horizon unit along the same wires that carry Ethernet traffic to the
Horizon unit. Unless you have the Release 1.2 PonE adapter, do
not, under any circumstances, plug cables connected to the
network into the RJ45 connectors marked "TO HORIZON
UNPROTECTED".
CAUTION
Only use straight through Ethernet cables to connect the PonE
adapter to the Horizon Compact Plus. Using cross-over cables will
result in damage to the Horizon Compact Plus unit.
CAUTION
Use shielded CAT5E cables with shields and drain wires
connected to metal head shells of RJ45 connectors, at BOTH ends
of cable for all unprotected, outdoor cable runs to Horizon Unit!
Use unshielded CAT5 cables and/or RJ45 connectors for
protected-side cable runs to network equipment.
