1. INTRODUCTION

1.1 Product Briefs

The switch is a un-management layer 2 10/100Mbps switch; it provide dedicated 10,

100 ,1000Mbps Ethernet bandwidth on each port. The ports will automatically detect the

speed, duplex and MDI/MDIX status of the device it is connecting to, and adjust these

settings accordingly. The Switch ports can be used to network computers, printers, servers,

routers, other switches or any device equipped with an Ethernet port. For best performance,

use Category 5 or better Ethernet cabling.

This stand-alone Switch is very easy to set up, there is no network management required. Just

power on the Switch and connect the cables. Keep in mind however that the standard rules of

Ethernet regarding cable length apply to this and all Ethernet devices. The length of an

Ethernet cable from one device to another cannot exceed 100 meters (or 300 feet).

1.2 Product Features

The Switches do not require any management. All Switches are designed for easy installation,

flexibility and high performance. Connect devices to the Switch as the scale and volume of

network traffic increases.

16 10/100/1000Mbps Gigabit ports

Auto-Negotiation for 10/100/1000Mbps and duplex mode

Auto-MDI/MDIX for each port

Supports Full/Half-duplex transfer mode for 10 and 100Mbps

Full wire speed reception and transmission

Store-and-Forward Switching method

Supports 8K absolute MAC addresses

16-Port Switch Supports 340KB RAM for data buffering

IEEE 802.3x flow control for Full-duplex

Back pressure flow control for Half-duplex

Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure,

format, and support for CSMA/CD protocol, full duplex, flow control, and management

objects, but with a tenfold increase in theoretical throughput over 100-Mbps Fast Ethernet

and a hundredfold increase over 10-Mbps Ethernet. Since it is compatible with all 10-Mbps

and 100-Mbps Ethernet environments, Gigabit Ethernet provides a straightforward upgrade

without wasting a company’s existing investment in hardware, software and trained

personnel.

The increased speed and extra bandwidth offered by Gigabit Ethernet is essential to coping

with the network bottlenecks that frequently develop as computers and their bus speeds get

faster and more users use applications that generate more traffic. Upgrading key components,

such as your backbone and servers to Gigabit Ethernet can greatly improve network response

times as well as significantly speed up the traffic between your subnets.

1.3.1 Product Appearance

1．Front Panel

The figure below shows the front panel of the Switch.

16-Port Gigabit Switch Front Panel

2．Rear Panel

The figure below shows the rear panel of the Switch. All MDI/MDI-X ports and an external

DC power adapter jack in the 16-port rear panel. There is a AC inlet in the 16-Port switch rear

panel.

16-Port Gigabit Switch Rear Panel

Auto MDI/MDI-X Ports:

All ports support automatic MDI/MDI-X crossover detection. The AutoMDI/MDI-X function

makes it simple to connect to the switch—just plug either a Crossover or Straight-Through

CAT5 cable into any port.

DC Power Jack:

Power is supplied through an external DC power adapter. Check the technical specification

section for information about the DC power input voltage.

AC inlet

Power is supplied through external AC power. The input AC voltage is 100~240V.

2. CONNECTING THE SWITCH

2.1 Package Contents

Open the shipping carton of the Switch and carefully unpack its contents.

The carton should contain the following items:

One 16-Port 10/100/1000BASE-T Gigabit Ethernet Switch

Four rubber feet with adhesive backing

One power Cord

Mounting ears for rack-mounting

CD-ROM with product documentation

If any item is found missing or damaged, please contact your local reseller for replacement.

2.2 Before You Connect to the Network

The site where you install the Switch may greatly affect its performance. Please follow these

guidelines for setting up the Switch.

Install the Switch on a sturdy, level surface that can support at least 3 kg (6.6 lbs) of

weight. Do not place heavy objects on the Switch.

The power outlet should be within 1.82 meters (6 feet) of the Switch.

Visually inspect the power cord and see that it is fully secured to the AC power port.

Make sure that there is adequate space for proper heat dissipation from and adequate

ventilation around the Switch. Leave at least 10 cm (4 inches) of space at the front and

rear of the Switch for ventilation.

Install the Switch in a fairly cool and dry place for the acceptable temperature and

humidity operating ranges.

Install the Switch in a site free from strong electromagnetic field generators (such as

motors), vibration, dust, and direct exposure to sunlight.

When installing the Switch on a level surface, attach the rubber feet to the bottom of the

device. The rubber feet cushion the Switch, protect the casing from scratches and prevent

it from scratching other surfaces.

2.3 Mounting ears for rack-mounting

The 16-Port Gigabit Switch can easily be mounted on a rack. Two mounting ears are

provided for this purpose. Make sure that the front panel is exposed in order to view the

LEDs. Please refer to the following illustrations:

Mounting the Switch to a Rack

1. Attach the ears to each side of the Switch, using the screw-holes located on the side of the

device.

2. Firmly attach the ears to the rack as shown. Please follow the usual safety precautions for

rack-mountable products.

2.4 Attaching the Rubber Feet

Use rubber feet provided. Position and apply rubber feet to the underside of the 16-Port

Gigabit Switch.

Attaching the Rubber Feet

3. Connecting the switch

Cable Quality

For all connections to the Switch, use these rules to determine the Cable quality.

For connections to 10BASE-T and 100BASE-TX devices, use Category 5 or 5e

UTP/STP cable.

3.1 Switch to End Node or Server

End nodes include PCs outfitted with a 10, 100 Mbps RJ-45 Ethernet/Fast Ethernet

Network Interface Card (NIC) and Ethernet ready routers. Use standard Ethernet cable to

connect the Switch to end nodes. Switch ports will automatically adjust to the hardware

characteristics (MDI-II/MDI-X, speed, duplex) of the device to which it is connected. Switch

connected to an end node

NOTE: UTP (Unshielded Twisted Pair) Ethernet cabling is adequate for

most small office environments. More expensive STP (Shielded Twisted

Pair) can also be used, but is generally only needed where there will be

risk of strong Electromagnetic of Radio Frequency Interference.
