10M or 100M
Link LED is
off on a
connected
por t.
Port
connection
is not
functioning.
Make sure the attached device is
powered and there is a proper UTP
connection.
Make sure the network adapter card
installed in the PC is working. Verify that
the network adapter card is operating at
the proper speed (10 Mbps or
100 Mbps).
Make sure the proper cable is installed.
Check for miswired cable pairs or loose
connectors.
For 100 Mbps operation, only
Category 5 or better grade cable should
be used. For 10 Mbps operation,
Category 3 cable can be used.
Make sure the length of the UTP cable
from the switch to the device does not
exceed 328 feet (100 meters).
100M link
and 10M link
are off on
por t 5.
Port
connection
is not
functioning.
Check the Normal/Uplink push button on
the front panel. Toggle the switch to the
alternate position for 10 seconds to see
if link comes on (refer to “Normal/Uplink
Push Button” section in this document
for the correct settings).
Green 100M
LED is off
when
operating in
a Fast
Ethernet
network.
Port is
operating
in 10 Mbps
mode.
Make sure the adapter card is capable of
and set for 100 Mbps operation if it is not
autosensing.
Green Link
10M or 100M
LED is on
and Green
FDX LED is
off when
connected to
a full-duplex
network.
Port is
operating in
half-duplex
mode.
Make sure the connected device is
capable of full-duplex transmission,
using autosensing. The Model FS105
switch will not support a full-duplex link
that is not advertised using autosensing.
Yellow
Collision LED
is blinking
excessively.
Data
collision is
occurring
on the port.
The port and switch might be functioning
correctly. However, check the following
to make sure that excessive collisions
are normal (as in most Ethernet
networks) and not caused by:
Incorrect cabling or connectors
Wiring techniques
Mismatched duplex operating mode
settings
