5.0 Powering the Horizon Compact

Before an active management session can be started on the Horizon Compact, power needs to be

provided to the unit. Read this section completely before applying power to the Horizon Compact.

5.1 Copper Interface

The Horizon Compact with copper interface receives its power over the Ethernet connection to Port 1

using a DragonWave proprietary technique. To integrat e the power onto the Ethernet cable requires the

use of the DragonWave Power on Ethernet (PonE) adapter. The DragonWave PonE adapter also

includes transient and surge suppression components to protect the power supply and network from

lightning induced surges and transients.

Note: The Horizon PonE implementation is proprietary and does not follow IEEE standards.

CAUTION

Only use a straight-through Ethernet cable to connect the Horizon to the PonE/surge unit.

Do not use a cross-over Ethernet cable otherwis e damage to the Horizon will result.

Figure 5-1 Connecting Power to the Horizon Compact – copper interface

CAUTION Connect the Horizon Compact unit to the PonE adapter correctly BEFORE turning on

power.

1. Connect Port 1 of the Horizon Compact to the correct socket on the PonE adapter using a

straight through Ethernet cable (see caution above).

2. Connect the Ethernet port on the PC to the network input socket on the PonE/surge unit, using a

straight through Ethernet cable.

Ensure that you have connected the PC and Horizon to the correct RJ-45 sockets on the PonE/surge unit

(see diagram above).

3. Once the PC and Horizon Compact are connected to the PonE/surge unit, you may connect

power to the PonE/surge unit. This will supply power to the Horizon Compact unit.

CAUTION Do not connect a PC or other network device (e.g. network switch) to the right hand RJ-

45 sockets on the PonE adapter. -48 V DC is present on these connectors which may destroy the

connected device. Connect only a Horizon Compact unit to the right hand RJ-45 connectors.
