10/100/1000BASE-TX (PoE) Ports
Ports that support Power over Ethernet provide power to networked
devices such as IP Phones, Wireless LAN Access Points, and IP security
cameras with a power budget of 360 Watts.
PoE 90W Limitation
When using PoE ports at 90 Watts, use PoE ports – 1, 4, 8, and 9 for
90W PoE. See example below:

100/1000M SFP Ports
SFP transceivers can be installed directly into SFP slots. Ensure that the
same type of transceiver is used at both ends of the link and that the
correct type of fiber cable is used.

Apply Power
➢ The switch has two pairs of power inputs.
➢ Only one power input is required to operate the switch. However,
redundant power supply functionality is supported.
52V/4.97A 57V/4.54A
➢
Note: Use qualified power supply by SELV or double insulation of
➢
UL60950 or UL61010-1 or UL61010-2-201 standards.
Terminal Block
The switch provides two power inputs on a 52-57VDC terminal block. The
terminal block has 5 terminal posts.

Digital IO-Setting
Connecting the Digital Inputs
The pin definitions for the digital input module are shown below. Each digital
input consists of two contacts on the 5-pin connector located on the top of
the switch. The inputs can be wired as either dry or wet contacts.
Dry Contacts:
[DI1-/GND] [DI2-/GND]
Logic level 1: Close to GND( )
10mA
Logic level 0: Open
Wet Contacts:
[DI1+/DI1-] [DI2+/DI2-]
Logic level 1 (High): 13~30 Volts (
3.2mA)
Logic level 0 (Low): 0~3 Volts
Configuring Digital Input Alarms Using the Web Interface
Located under the Diagnostics group, the Digital IO-Setting page allows for
quick configuration and enabling of digital input and environmental alarms.
