Power Connectors

You connect the DC power to the switch through the front panel connectors. The switch has a dual-feed DC power
supply; two connectors provide primary and secondary DC power (DC-A and DC-B). The DC power connectors are near
the top right of the front panel. See
The switch power connectors are attached to the switch chassis. Each power connector has screw terminals for
terminating the DC power (see
provided captive screws.
The power connector labeling is on the panel. The positive DC power connection is labeled "+", and the return
connection is labeled "–".
Figure 7 Power Connector
The switch can operate with a single power source or with dual power sources. When both power sources are
operational, the switch draws power from the DC source with the higher voltage. If one of the two power sources fails,
the other continues to power the switch.
In systems configured with the redundant power option, connect each of the two power supplies to separate
independent power sources. If you fail to do this, your system might be susceptible to total power failure due to a fault
in the external wiring or a tripped circuit breaker.
The switch can be powered from a site source or a 50 Watt AC-input power supply module (part number
PWR-IE50W-AC=). For more information on wiring the DC power source, see
information on power consumption, see

PoE Power Connector

The IE 2000U switch model with PoE capability (IE 2000U-16TC-GP) is equipped with an additional DC input terminal
block. This DC terminal block allows the connection of a power supply, either the PWR-IE65W-PC-AC= or PWR-IE170W-
PC-AC= AC Input power supply or the PWR-IE65W-PC-DC= or PWR-IE170W- PC-DC= DC Input power supply, or an
input from site source DC that is used to provide dedicated external power to operate the PoE or PoE+ ports. The PoE
terminal block accepts 48 VDC or 54 VDC at 2.5 A.

Alarm Connector

You connect the alarm signals to the switch through the alarm connector. The switch supports two alarm inputs and one
alarm output relay. The alarm connector is on the bottom right of the front panel. See
SFP Module Cables, page
Figure 1 on page 12. Each power connector has an LED status indicator.
