Introduction

General Description

Easily boost your networking throughput, this product provides you 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.

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 ensures the correctness of data 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.

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.
