 Identify a power source within 6 feet (1.8
meters).
 Choose a dry area with ambient
temperature between -40 and 75ºC (-40
and 167ºF).
Keep away from heat sources, sunlight,

warm air exhausts, hot-air vents, and
heaters.
 Make sure there is adequate airflow.

Connect to the Ports
The EX46910 has the following ports:
8 10/100/1000 Mbps PoE ports

2 gigabit SFP slots shared with 2 1000

copper ports (ports 9 & 10)
10/100/1000BASE-T Ports
Ports 1 to 8 are gigabit copper ports that are
compliant with IEEE 802.3af/at PoE protocol,
with up to 30W power output per port.
1 Gbps Combo TX/SFP Ports
Ports 9 and 10 are combo ports and have two
physical interfaces. One interface is a
1000BASE RJ45 port and the other interface is
a 1000BASE SFP slot. These ports operate in
"either or" fashion. Both cannot be used
simultaneously.

Connect Power
Terminal Block
Connect the unit to a suitable power supply
using appropriate wire, 18-24 AWG, rated for
105°C or higher.
Redundant power is supported. However,
only one power input is required to operate
the unit.
1. Connect power wires to the
appropriate P1+/- or P2+/- pins on
the terminal block.
2. Connect the grounding wire to the
ground screw.
3. Plug the terminal block into the
socket.
4. Alternatively, connect power 3 to an
external power adapter.
Relay Output Alarm
The switch provides relay output contacts for
redundant power. The relay output can be
connected to an alarm signaling device. The
current capacity is 1A@24VDC.
When dual power sources are connected,

the circuit is open.
When a single power source is connected

the circuit is closed.
The relay works with only power 1 and

power 2. It is not connected to power 3.
