Unpacking Information
Thank you for purchasing this product. Before installation,
please verify that your packa ge contains the following items.
1. 4-Port Gigabit Ethernet Switch with 1-Port Mini-GBIC
2. One power adapter
3. User’s Manual
Introduction
General Description
Easily boost your networking throughput; the product
equips 4 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, 1 of the ports
supports fiber connection with the equipped Mini-GBIC ports
for obtaining long-distance co mmunication.
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 s
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 a nd 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.

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.

1. Crossover or straight-through ca ble: 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 optima l performance. Appropriate
cables corresponding to different transmitting/receiving
speed is required. To choose a suitable cable, please refer to
