Model EN104TP/EN106TP/EN108TP Ethernet Hub Installation Guide

To complete the installation, connect the power cord ﬁrst to the power receptacle

on the hub rear panel and then to the power outlet on the wall. When power has

been applied to the hub:

• The green Pwr (Power) LED on the front panel is on.

• The green Link LED on each connected port is on.

If there are any problems, refer to “Troubleshooting Information.”

Refer to this table and the information that follows the table to troubleshoot your

hub.

Network Interface Cards

Make sure the network interface cards installed in the workstations are in

working condition and the software driver has been installed.

Symptom Cause Solution

Amber Col

LED blinks.

Collisions are

occurring on

the network.

Data collision is normal on Ethernet networks. No action

is required.

Amber Col

LED blinks

quickly.

Collisions are

occurring on

the network,

because the

network is

busy or is

defective

devices are

connected on

the network.

Make sure connected devices are operating in half-

duplex mode. The hub is not compatible with devices that

operate in full-duplex mode.

If you suspect that there might be a defective device on

the network, disconnect devices one at a time to isolate

the defective unit on the network.

If the network is extremely busy, you may have to

segment the network with an Ethernet switch such as a

NETGEAR Ethernet switch or to upgrade your network to

Fast Ethernet operation.

Wrong or

miswired

cables are

used.

Make sure the correct UTP cables are used. See the

table in the installation section of this guide for cable use

and Normal/Uplink push button information. Note that

home telephone cables can cause a collision condition

and cannot be used in place of UTP cables.

Green Link

LED is off

when a cable

is attached.

The port is

not detecting

a successful

link.

Check for a bad cable, cable pairs that are not correctly

wired, or loose connectors. Make sure that there is power

to both the hub and the Ethernet transceiver on the

connected device. Make sure the port has not been

partitioned.

Green Rx

LED is off

when data is

transmitting.

The port is

not detecting

data

transmission.

Check for a bad cable, cable pairs that are not correctly

wired, or loose connectors. Make sure that there is power

to both the hub and the Ethernet transceiver on the

connected device. Make sure the port has not been

partitioned.
