Model FS308 Fast Ethernet Switch Installation Guide
Solution
Make sure the adapter card is capable of
100 Mbps operation and set for 100 Mbps
operation if it is not autosensing.
Make sure the duplex switch on the Model
FS308 Fast Ethernet Switch is set for full-
duplex operation. Make sure the connected
device is capable of full-duplex
transmission.
The port and switch might be functioning
correctly. Data collisions are normal on
Ethernet networks and occur when two or
more computers transmit data on the
network simultaneously. Computers that
caused the collision retry transmission at
different intervals until the transmission
succeeds. Excessive collisions can result
when multiple switches are connected and
when many computers are connected on
the network. Check and make sure that
cabling and duplex settings are correct.
