CheetaHub Power-3004E

Introduction

Accton’s CheetaHub Power-3004E is a compact dual-speed

hub featuring 4 10BASE-T/100BASE-TX auto-sensing ports.

This hub is completely plug and play, there is no configuration

necessary. Also, the hub comes with its own versatile hub

stand and can be mounted anywhere, so it’s ideal for small

workgroups.

The components of the CheetaHub Power-3004E are shown

in the figure below:

Quick Installation Guide

Side Panel RJ-45 Connectors

Accton’s CheetaHub Power-3004E features 4 10BASE-T/

100BASE-TX ports with RJ-45 connectors located on the side

panel of the hub. Port 1-4 are MDI-X, with a built-in wiring

crossover that allows for the use of straight-through twisted-

pair cable for connections to devices without built-in crossover

ports (i.e., workstations, printers, etc.).

Port 4 on this hub doubles as a crossover port and a straight-

through Uplink (daisy-chain) port. The MDI Uplink port makes

it convenient to connect straight-through cable from the hub to

a crossover port on another device.

Mount the Hub

The CheetaHub Power-3004E with its flexible stand can be

mounted on any flat or vertical

surface.

To mount the hub on a flat surface:

1 Slide the stand onto the hub base

(to stand upright) or back (to lay

flat).

2 Place the hub on any convenient

flat surface, such as a desktop or nearby shelf.

To mount the hub on a vertical surface:

1 First secure the stand to the

desired location, such as a

wall or side of a desk. You

may use two small screws,

Velcro™ strips, or any other

technique.

2 With the stand secured, slide the hub’s back

onto the stand.

Connect PCs to the Hub

Connect each PC to an RJ-45 port

on the hub with a straight-through

twisted-pair cable, maximum

100 meters (328 ft.). The

CheetaHub Power-3004E

will support up to 4 PCs.

Note that if you are using

port 4, be sure not to use

the Uplink port.

CheetaHub Power-3004E

Cascade Devices to the Hub

If you need more ports, connect a crossover port on another

device to the Uplink port on the hub with straight-through

twisted-pair cable, maximum 5 meters (16.4 ft.). Note that if

you are using the Uplink port you cannot use the fixed

crossover port on port 4.

1. Prepare staight-through

Category 5 twisted-pair

cable with RJ-45 plugs.

Make sure the cable does

not exceed 5 eters (16.4

feet).

2. Connect one end of the

cable to the hubs uplink

port. When using the Uplink

Port be sure not to use Port 4.

3. Connect the other end of the cable to an MDI-X RJ-45 port

on the other device (not an MDI port).

 Alternatively, you can connect fro any MDI-X port on the

hub to an MDI daisy-chain port on the other device.

 You ay also attach to MDI-X ports at both ends if you

use crossover cabling.

 When connecting to another 100Mbps Fast Ethernet

hub, the nu ber of cascaded hubs is li ited to two, and

the total network span allowed is only 205 eters (672

feet).

Verify System Operation

Check each connection by viewing the port status indicators

shown in the following table. The hub monitors the link status

for each port. If the Port indicator fails to light when you

connect a device to the hub, follow the troubleshooting advice

detailed in the next section.

Port and Hub Status LEDs

LEDs Condition Status

Power Green Hub is receiving power.

Flashing Traffic is traversing the port.

Memory Error Yellow Indicates the hub has failed its power-on

self test. If this occurs, contact your Accton

dealer for assistance.

Quick Installation Guide

Troubleshooting

Sy pto : Power LED does not light after power on.

Cause: Power outlet or power cord ay be defective.

Solution: 1. Check for loose connections.

2. Check the power outlet by using it for another

device.

3. Replace the power cord.

Sy pto : Port LED does not light after connection is ade.

Cause: Hub port, network card or cable ay be

defective.

Solution: 1. Check that the hub and attached device are

both powered on.

2. Be sure the network cable is connected to both

devices.

3. Verify that Category 5 cable is used for

100Mbps connections and Category 3 or

greater for 10Mbps connections. Also verify

that the axi u cable length does not exceed

5 eters (16.4 feet) when connecting to a

100Mbps hub, or 100 eters (328 feet) when

connecting to any other device.

4. Check the network card and cable connections

for defects.

5. Replace the defective card or cable if

necessary.
