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, four of these ports support 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 prevents 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 N-way
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
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.
Media Speed Wiring
10Mbps Category 3,4,5 UTP/STP
100Mbps Category 5 UTP/STP
10/100/1000Mbps copper
1000Mbps Category 5,5e UTP/STP
1000Mbps Fiber
(Mini GBIC required) 1000Mbps The 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 four ports, when both the fiber and cooper interfaces are
connected, the system adapts the fiber interface and disables the relevant cooper
port automatically.
Backbone Network Application
This switch is ideal for boosting the throughput of backbone. For an application sample of
network topology, please refer to the following chart.
