Verify the Installation
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."

Model EN104TP/EN106TP/EN108TP Ethernet Hub Installation Guide
Solution
Data collision is normal on Ethernet networks. No action
is required.
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.
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.
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.
