Refer to the information about LEDs given earlier in this guide to
see if the problem can be identified and rectified. Here are some
common problems that can occur:
Link Status LED not lit for a port that has a connection.
There is a problem with this connection. Check that:
The device being connected to is powered on and operating
correctly.
The cable is connected at both ends.
The cable is not damaged.
If the connection is to a workstation, that the workstation's
network interface is installed and configured correctly.
The correct category of cable is being used for the required
link speed. Category 3 cables can be used for 10BASE-T
operation only. Category 5 cables are required for
100BASE-TX or 1000BASE-T. 3Com recommends using
Category 5e cables for 1000BASE-T operation.
All ports appear to show continual activity. There may be
broadcast storms on the network.

und drehen Sie diese mit einem geeigneten Schraubendreher
fest.
4 Widerholen Sie letzten beiden Schritte auf der anderen Seite

6 Schließen Sie alle Kabel wieder an.
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.
If the problem persists and the unit still does not operate
successfully, contact your supplier with the following information
before returning the unit:
Product number and serial number (printed on a label
supplied with the unit)
A brief description of the fault
