The EX42395BT has the following ports:
4 10/100/1000 Mbps PoE ports
1 100/1000 SFP slot shared with 1
10/100/1000 copper port (port 5)
1 dedicated 100/1000 SFP slot
Ports 1 to 4 are gigabit copper ports that are
compliant with IEEE 802.3af/at/bt PoE
protocol, with up to 90W power output per
port. The ports are also backward compatible
with 95W PoH and 60W UPoE protocols.
1 Gbps Combo TX/SFP Ports
Port 5 is a combo port and have two physical
interfaces. One interface is a
10/100/1000BASE-T port and the other
interface is a 100/1000BASE SFP slot. These
ports operate in “either or” fashion. Both
cannot be used simultaneously.
Port 6 is a 100/1000BASE SFP slot.
Connect the unit to a suitable power supply

Redundant power is supported. However,
only one power input is required to operate
1. Connect power wires to the

The switch provides relay output contacts for
signaling of power failure. The relay output
can be connected to an alarm signaling
device. The current capacity is 1A@24VDC.
