Power Over Ethernet Switch(PoE) Installation and User Guide

5

DC POWER Input : built-in terminal block for +, -,
ground, -48V DC

input (range of 36 to 60V DC). The

Direct DC power input floats. User may ground either “+”
or “-” if desired.

Power Consumption

: 6 watts for the unit, up to 60 watts (30 to 40 typical) for attached

PoE devices. See Section 3.6.

Note 1:

The optional 8-15V DC jack can be used for dual source DC input using an AC

adapter and the DC terminal block. Power supply protection is provided by internal diodes.

Port Connectors:

Four RJ-45 Ports: support 100BASE-TX and 10BASE-T with auto-cross (MDIX).
They are shielded 8-pin female connectors for shielded (STP) and unshielded
(UTP) Cat 3, 4, 5 cable.

LED Indicators (Dual: front and top)

POWER: Steady ON when power applied

10/100: Steady ON for 100Mbps; OFF for 10 Mbps
