2 What Else You Need
Appropriate cable for data ports
Personal computer or laptop
3 Select a Location
Desktop installations: Mount on a flat table
or shelf surface.
Rack installations: Use a 19-inch (48.3-
centimeter) EIA standard equipment rack
that is grounded and physically secure.
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.
Be sure there is adequate airflow.
Keep the switch at least 6 ft. (1.83 m) away
from the nearest source of electromagnetic
noise, such as a photocopy machine.
4 Connect to the Data Ports
Depending on the model, your switch can have
the following ports:
4 or 8 10/100Base-TX Power over Ethernet
(PoE) ports. The PoE ports conform to
IEEE802.3af and provide up to 15W per port,
with a total power budget of 123.2W.
0 or 4 100Base-FX ports
0 or 2 Gigabit ports
10/100Base-TX and 100Base-FX Ports
These ports can connect to devices such as an IP
surveillance camera or a Voice Over Internet
Protocol (VoIP) phone.
A. Insert one end of an appropriate cable into a
switch port.
B. Connect the other end into the Ethernet port
of the device.
C. Repeat steps A and B for each additional
device you want to connect to the switch.
Gigabit Ports
Some switch models have 2 10/100/1000Base-TX
ports, 1000Base-SX/LX/BX ports, or 1000Base SFP
ports. You can connect these ports to network
devices such as a computer, printer, network
video recorder (NVR), network storage, or they
can connect to the network itself.
Wear an ESD-preventive wrist strap before
connecting to these ports.
5 Apply Power
The switch has two pairs of power inputs: a 47-
57VDC terminal block and a 48VDC jack. Only
one power input is required to operate the
switch. However, redundant power supply
functionality is supported.
Terminal Block
The switch provides two power inputs on a 12-
48VDC terminal block. Only one power input is
required to operate the switch.
