Make sure the network interface cards installed in the workstations are in
working condition and the software driver has been installed.
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

Fast Ethernet is conventional Ethernet but faster. Fast Ethernet, or 100BASE-
TX, operates at 100 Mbps instead of 10 Mbps. The 100BASE-TX technology
uses the same frame format and length as Ethernet and does not require changes
to the upper-layer protocols, applications, or networking software that run on
Amber Part LED turns on. The connected port is
partitioned because of
excessive collisions.
The 100BASE-T RJ-45 port
is partitioned after 32
consecutive collisions are
detected. When the first
good packet without a
collision is received, the
port is reconnected and the
amber Partition LED turns
off. Check and correct
causes listed in this table for
excessive collisions and
make sure that:
The correct cable is used
and the cable is not faulty.
There are no faulty
connectors.
The network card in your
PC is set to half-duplex
mode.
Green Link/Rx LED on the
100BASE-T port is off when
a cable is attached or not
blinking when there is data
transmission.
The port is not detecting a
successful link or data
transmission.
Check for a bad cable, cable
pairs that are not correctly
wired, or loose connectors.
Make sure that there is
power to the hub and the
connected PC. Make sure
the port has not been
partitioned.
Make sure the network card
in the connected PC is
configured for 100 Mbps
operation.
If the Green Link/Rx LED is
on port 16, also check to
make sure the Normal/
Uplink push button switch is
set according to the
instructions in “Installation
Procedures.”
