These SE Series unmanaged switches oer high-performance, plug-and-play,
gigabit Ethernet switching with 16/24 gigabit Ethernet ports and two gigabit SFP
ports, providing you a cost-eective, space-saving solution for expanding your
network. The fully gigabit Ethernet ports support high bandwidth for today’s most
demanding applications. The two SFP ports provide the ability to add fiber-optic
connectivity between other network switches, giving you the option for long-distance
communications.
Automatic MDI/MDI-X crossover detection ensures you will not need to worry about
the cable type by automatically switching the port’s receive and transmit connections
with plugged in devices. Also, flow control ensures the accuracy of transmitted data.
What’s more, the 802.3x and back-pressure flow control mechanisms work respectively
for full- and half-duplex modes.

Power receptacle
To be compatible with worldwide electric service standards, the switch is designed to
use the power supply in the range from 100 to 240VAC, 50/60 Hz. Make sure that your
outlet standard is within this range.
To power on the switch:
1 Connect the power cord securely into the power receptacle on the back of the
switch and to an electrical outlet.
2 Verify that the power LED on the front of the switch is on and indicating normal
power status.
Installation
This switch can be placed directly on your desktop or mounted in a rack. All features of
the switch are available while the switch is powered on.
Desktop installation
1 Attach the provided rubber feet to the bottom of the switch to keep the switch
from slipping. The recommended position has been marked with a small square.
2 Place the switch on a level surface that can support the weight of the unit and the
relevant components.
3 Connect the power cord to the switch and an electrical outlet.

Rack-mount installation
The switch can be mounted in a standard 19" rack. Rack mounting produces an orderly
installation when you have several related network devices. The switch is supplied with
two optional mounting brackets and screws.
To rack mount the switch:
1 Disconnect all cables from the switch.
2 Place the switch on a hard, flat surface with the front facing you.
3 On each side of the switch, position a mounting bracket over the bracket
mounting holes, then insert and fully tighten the screws with a screwdriver.
4 Using the mounting brackets, mount the switch into the equipment rack with the
appropriate screws.
5 Reconnect all cables.

Network cable guidelines
• Crossover or straight-through cable: All ports on the switch support Auto-MDI/
MDI-X. Straight-through and crossover cables can be used to connect the switch
with PCs, as well as other devices such as switches, hubs, or routers.
• Category 5, 5e, 6a, or 7 UTP/STP cable: To make a valid connection and obtain
optimal performance, appropriate cables corresponding to dierent transmitting/
receiving speeds are required. To select a suitable cable, refer to the table below:

Wiring
Tips: To ensure optimal performance, we strongly recommend the below installation
environment:
• The switch has sucient ventilation. A minimum 1 inch (about 25 mm) space
around the unit is recommended.
• The switch and the relevant components are kept away from sources of electrical
noise, such as radios, transmitters, and broadband amplifiers.
• The switch is kept away from moist environments.
