the connected device closer to the
switch and use a shorter cable.
A 10/100Base-T-capable device or
1000Base-T half-duplex device is
connected to a 1000Base-T port
(ports 25 and 26) on a
PowerConnect™ 2324 switch.
Connect only 1000Base-T full-
duplex capable devices to ports 25
or 26 on the PowerConnect 2324
switch.
Mismatched duplex mode.
Ensure that all devices connected
to the switch are configured to
automatically detect and set port
