Powering Up the Network Extender

The DC power terminal block on the network extender has five terminals: two positive,

two negative, and one ground. Only one positive terminal and one negative terminal pair

need be connected for operational purposes. The second positive and negative terminal

pair may be connected to a backup DC power supply for redundancy. The ground

terminal must be connected regardlessly. DO NOT OPERATE THE NETWORK

EXTENDER WITHOUT A GROUND CONNECTION UNLESS IT IS POWERED BY

THE SUPPLIED AC POWER ADAPTER.

Procedure

1. Loosen all screws at the top of the power terminal strip.

2. Insert your ground wire in the center terminal and tighten the screw.

3. Insert your –48 VDC lead into the negative (–) terminal of a terminal pair. Tighten

the screw for that terminal.

4. Insert your 48 VDC return lead into the positive (+) terminal of the same terminal

pair as in Step 3. Tighten the screw for that terminal.

5. Repeat Step 3 and Step 4 for the free pair of power terminals if you have a

redundant power supply.

6. Verify that the Power LED on the front of the network extender is illuminated.
