Table 5-1. Troubleshooting Information
Symptom
Power LED is off.
Either 10M, 100M, or
1000M Link LED is off or
intermittent.
File transfer is slow or
performance degradation
is a problem.

Troubleshooting

Cause
No power is received at
the hub.
Port connection is not
functioning.
Half- or full-duplex setting
on the NETGEAR switch
and the connected device
are not the same.
Troubleshooting
Solution
Check the power cord connections for the switch
and the connected device.
Check for a defective adapter card, cable, or port
by testing them in an alternate environment where
all products are functioning.
Make sure all cables used are correct and comply
with Ethernet specifications.
Check the crimp on the RJ-45 connectors or fiber
connectors and make sure that the plug is properly
inserted and locked into the port at both the switch
and the connecting device.
Make sure all cables used are correct and comply
with Ethernet specifications. All fiber cables must
be crossover cables for proper communication
between the transmit and receive signals to take
place.
Make sure the 10/100 Mbps port is set to
auto-duplex (AUTO) mode when connecting the
switch to a repeater or hub. For instructions on
setting the duplex toggle switches, refer to
"Connecting Devices to the Switch" on page 4-4.
