Ethernet Hub Installation Guide
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.
Hub Integrity
If required, verify the integrity of the hub by resetting it. Turn power to the
switch off and then back on. If the problem continues and you have completed
all the preceding diagnoses, contact NETGEAR Customer Support. For the
phone number of the representative in your area, see “Customer Support.”
Symptom Cause Solution
Amber Col LED
blinks.
There is data collision
on the network.
Data collision is normal on Ethernet
networks. No action is required.
Amber Col LED
blinks excessively.
There is data collision
on the network
because the network is
extremely busy or
defective devices are
connected on the
network that cannot
detect network traffic or
collision.
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 is off
when there is data
transmission.
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.
