Port Status LED not lit for a port that has a TP cable
connected. After connection, it may take several seconds for
the Port Status LEDs to illuminate. The Port Status LED should
turn, Green for each port that is connected. Please refer to
'About Your Switch' for a full description of the LEDs.
If the Port Status LED is not lit after several seconds, ensure
that the connected device is powered on, that the TP cable is
not damaged and that it is correctly inserted at both ends.
You may find that a TP cable works when connected to the
Switch, but that it does not if disconnected from the Switch
and connected to another device. This may be because the
other device does not have the automatic MDI/MDIX feature.
The Port Status LED is lit but the network performance of
the switch is poor. The switch supports full-duplex autonego-
tiation. If the connected device does not support autonegotia-
tion, ensure it is configured for half duplex operation only.
