Introduction

GEU-0520 and GEU-0820 are members of LevelOne

Unmanaged Switch 2 series which are powerful,

high-performance Gigabit Ethernet switches. With 5 or 8

ports capable of 10/100/1000 Mbps auto-negotiation

operation (NWay), the switch could automatically

negotiate with the connected partners on the network

speed and duplex mode. It is ideal for micro-segmenting

large networks into smaller, connected subnets for

improved performance, enabling the bandwidth

demanding multimedia and imaging applications.

Moreover, the 10/100/1000Mbps auto-sensing ability

provides an easy way to migrate 10/100Mbps to

1000Mbps network. Compared to the shared 10Mbps or

100Mbps networks, the switch delivers a dedicated

10/100/1000Mbps connection to every attached client

without bandwidth congestion issue. This switch also

supports auto MDI/ MDI-X function. Each port could be

used to connect to another switch or hub without

crossover RJ-45 cable.

Store-and-forward switching mode promises the low

latency plus eliminates all the network errors, including

runt and CRC error packets. To work under full-duplex

mode, transmission and reception of the frames can

occur simultaneously without causing collisions as well as

double the network bandwidth. Moreover, Pre-IEEE

802.3az Energy Efficient Ethernet is supported to save

power consumption

GEU-0520 and GEU-0820 are plug and play without any

software to configure and also fully compliant with all

kinds of network protocols.

Quick Installation Guide

This section provides unpacking and setup information for

the Switch.

Unpacking

Open the shipping carton and carefully unpack its contents.

The carton should contain the following items:

One GEU-0520, or GEU-0820 Gigabit Ethernet Switch

Four rubber feet with adhesive backing

Wall-mount Kit

One external power adapter

QIG Manual

If any item is found missing or damaged, contact your local

dealer for a service.

Installation

The site where you install the Switch stack may affect its

performance. Use the following guidelines when installing

the switch:

Install the Switch in a cool and dry place. See

specifications 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.

Leave at least 10 cm of space at the front and rear of the

hub for ventilation.

Install the Switch on a sturdy, level surface that can

support its weight. When installing the Switch on a level

surface, attach the rubber feet to the bottom of each

device. The rubber feet cushion the hub and protect the

hub case from scratching.

Wall Mounting

Before you begin, you need 2 wallboard screws to mount

the unmanaged switch.

To mount the unmanaged switch to the wall:

1. Determine where you want to mount the unmanaged

switch. Verify that the surface is smooth, flat, dry, and

sturdy.

2. Drill two pilot holes into the wall surface. The

wall-mount slots are two crisscross slots on the bottom

panel of the unmanaged switch.

3. Insert a screw into each hole, leaving a gap between the

surface and the base of the screw head of at least 0.1

inches (3 mm).

4. Place the unmanaged switch wall-mount slots over the

screws and slide the unmanaged switch down until the

screws fit snugly into the wall-mount slots.

5. Connect the unmanaged switch to the other devices, as

described in the “Connecting the Equipment” section.

Flat Surface Installation

To deploy the device on a desktop or other flat surface:

1. Place the unmanaged switch on a desktop near an AC

power source.

2. Connect the unmanaged switch to the other devices, as

described in the “Connecting the Equipment” section.

Connecting the Equipment

This section describes the process for connecting the

device to the network.

1. Power down all of the devices you want to connect to

the switch.

2. Connect the Ethernet cable to the Ethernet port of a PC,

printer, network storage, or other network device.

NOTE We recommend using Cat5e or better cable.

Also, do not exceed the maximum cabling distance of 328

feet (100 meters) per segment.

For cable selection, refer to the following table：

Network Speed Cable Type Max. Length

10Mbps Cat. 3, 4, 5 UTP/STP 100 meters

100Mbps Cat. 5 UTP/STP 100 meters

1000Mbps Category 5e, 6 UTP/STP 100 meters

3. Connect the other end of the network Ethernet cable to

one of the numbered unmanaged switch Ethernet ports.

4. Repeat Step 2 and Step 3 for each device you want to

connect to the unmanaged switch.

CAUTION Make sure you use the power adapter

included with the switch. Using a different power adapter

might damage the switch.

5. Connect the power adapter to the power port on the

back panel of the unmanaged switch.

6. Power up the devices connected to the switch.

Magnet Mounting

This model support magnet mounting

Introduction to magnetic mounting parts

There are two permanent magnets in the bottom of switch,

as shown in below figures.

GEU-0520

GEU-0820

Installation procedure

Attach the magnet-mounted device to the specified

location. Take care not to get your fingers stuck between

because the magnetism is very huge.

CAUTION

Select the installation location carefully. In the case of

poor surface, magnet mounting may not be reliable.

Put the device at a stable place free from vibrations or

shocks. Otherwise, personal injuries or equipment

damage may occur.

Avoid installing the device at a high place because

personal injuries or equipment damage may occur in

case of a falloff.

Avoid frequently moving the desk-mounted device

because such movements may damage the surface

coating.

Keep the front panel of the device facing upwards and

the two sides with ventilation holes vertical to the

ground, if you want to install the device vertically.

Pay attention that the weight of external cables should

not bring about a falloff, which may result in personal

injuries or equipment damage.

Keep floppy disks and magnetic cards away from

magnets to avoid erasure of any information.

Keep computers and monitors that are easily influenced

by magnetic fields away from magnets. Otherwise, faults

may occur to these electronic devices.

Power On

Plug one end of theca power adapter into the power

connector on the switch and the other end into the local

power source outlet.

After the switch is turned on, the LED indicators will

momentarily blink, showing a reset of the system.

Power failure

If a power failure occurs, unplug the switch. When power

is resumed, plug the switch back in.
