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 copper 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

5
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.

he cable type differs from
the Mini-GBIC you choose.
Please refer to the instruction
came with your Mini-GBIC.
Port Operation
The auto-negotiation feature allows ports running at one of
the following operation modes:
Media Speed Duplex Mode
Full Duplex10Mbps Half Duplex
Full Duplex100Mbps Half Duplex
10/100/1000Mbps
(copper)
1000Mbps Full Duplex
1000Mbps(Fiber)
(Mini-GBIC required) 1000Mbps Full Duplex
Note: For the last port, when both the fiber and copper
interfaces are connected, the system adapts the fiber
interface and disables the relevant copper port
automatically.
