switch
Rack-mounting hardware brackets
One CD containing this user’s guide
If items are missing or damaged, notify your

2 What Else You Need
Appropriate cables 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, 6, or 8 10/100/1000Base-TX ports
0, 1, or 2 Gigabit ports
10/100/1000Base-TX 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 1 or 2 1000Base-
SX/LX/BX 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.
Combo ports operate in “either/or” fashion. This
means that attaching to a 1 Gbps combo port
renders the equivalent partner combo port
unavailable. See the following example.
5 Apply Power
The switch has two pairs of power inputs:
A 12-48VDC terminal block
A 12VDC 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. The terminal
block has 5 terminal posts.
