Unpacking Information
Thank you for purchasing this product. Before installation,
please verify that your package contains the following items.
1. One 16/24-Port Gigabit Ethernet Switch with
4-Port Mini-GBIC
2. One AC power cord
3. Rack-mount brackets (optional)
4. User’s Manual
Introduction
General Description
Easily boost your networking throughput; the product
equips 16/24 Gigabit ports that lead you to a real Gigabit
connection. Users are now able to transfer large and high
bandwidth-needed files faster and hence get a real efficiency
improvement. In addition to the cooper ports, 4 of the ports
supports fiber connection with the equipped Mini-GBIC ports
for obtaining long-distance communication.
This product offers users with fast and reliable network.
The store-and-forward architecture filters errors and forwards
packets in a non-blocking environment. Flow control prevent
data loss while transmitting. The 802.3x and backpressure
flow control mechanisms work respectively for full and half
duplex modes.
The switch features with easy installation and maintenance.
It supports Nway auto-negotiation protocol that detects the
networking speed (10/100/1000 Mbps) and the duplex modes
(Full/Half) automatically. Auto-MDI/MDI-X function alleviates
the effort to use crossover cables. Also, rich diagnostic LEDs
are provided for users to get real-time information of the
connection status.

The Rear Panel
Power Receptacle
To be compatible with the electric service standards around
the world, the switch is designed to afford the power supply in
the range from 100 to 240VAC, 50/60Hz. Please make sure
that your outlet standard to be within this range.
To power on the switch, plug the female end of the power cord
firmly into the receptacle of the switch and the other end into
an electric service outlet. After the power cord installation,
please check if the power LED is illuminated for a normal
power status.
Installation
This switch can be placed on your desktop directly, or mounted
in a rack. The installation is a snap. Users can use all the
features of the switch with simply attaching the cables and
turning the power on.
Before installing the switch, we strongly recommend:
1. The switch is placed with appropriate ventilation
environment. A minimum 25mm space around the unit
is recommended.
2. The switch and the relevant components are away from
sources of electrical noise such as radios, transmitters
and broadband amplifiers
3. The switch is away from environments beyond
recommend moisture

6
Desktop Installation
1. Attach the provided robber feet to the bottom of the
switch to keep the switch from slipping. The
recommend position has been square-marked.
2. Install the switch on a level surface that can support
the weight of the unit and the relevant components.
3. Plug the switch with the female end of the provided
power cord and plug the male end to the power outlet.
Rack-mount Installation
Rack mounting facilitate to an orderly installation when
series of networking devices being installed. The switch is
supplied with rack mounting brackets and screws for rack
mounting the unit.
Procedures to Rack-Mount the Switch in the rack:
1. Disconnect all the cables from the switch before
continuing.
2. Place the unit the right way up on a hard, flat surface
with the front facing you.
3. Locate a mounting bracket over the mounting holes on
one side of the unit.
4. Insert the screws and fully tighten with a suitable
screwdriver.
5. Repeat the two previous steps for the other side of the
unit.
6. Insert the unit into the rack and secure with suitable
screws (optional).
7. Reconnect all the cables.

Network Cables Installation
1. Crossover or straight-through cable: All the ports on
the switch support Auto-MDI/MDI-X functionality. Both
straight-through or crossover cables can be used to connect
the switch with PCs as well as other devices like switches,
hubs or router.
2. Category 3,4,5 or 5e UTP/STP cable: To make a valid
connection and obtain the optimal performance. Appropriate
cables corresponding to different transmitting/receiving
speed is required. To choose a suitable cable, please refer to
the following table.
