The Dual Speed Hub 500 has been designed to aid you when
detecting and solving possible problems with your network. These
problems are rarely serious, the cause is usually a disconnected or
damaged cable, or incorrect configuration.
This chapter has information on solving management problems, that
involves the use of the management module. If the information given
does not solve your problem, contact your supplier for information
on what to do next. If you have a problem with the unit, refer to the
user guide that accompanies the unit.
If you have a problem with the serial web utility, refer to

Perform these actions first:
■
Ensure that any equipment to be attached to the Dual Speed Hub
500 has the latest version of its driver software installed,
especially any network interface card.
■
Ensure all equipment is powered on.
■
Power each unit off, wait about 5 seconds and then power them
on so they perform a self test. The self test only takes a few
seconds, during which the Power/Self Test LED flashes.
