If The Problem Persists - 3Com 3C16476CS User Manual

Ensure that the connected device has either:
Autonegotiation enabled, or
■
The ports are configured for half-duplex operation
■
All ports appear to show continual activity.
There may be broadcast storms on the network.
Remove port connections one at a time, waiting a
few seconds between each port. If the LEDs go off
after removing a port connection, the device that was
connected to that port is introducing an excessive
amount of broadcast frames to the network. Some
pieces of network equipment operate by sending out
broadcast frames regularly.
Refer to the documentation that accompanies the
device for information on disabling the broadcast
operation.
