The OfficeConnect Switch 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. If this section does not
solve your problem, contact your supplier for
information on what to do next.
Perform these actions first:
Ensure all equipment is powered on.
Power each unit off, wait about 5 seconds and then
power them on.
Check the following symptoms and solutions:
Power LED not lit.
Check your power adapter
connection. If there is still no power, you may have a
faulty power adapter which needs replacing with an
identical OfficeConnect power adapter.
Do not use
any other power adapter with the Switch.
Port Status LED (Switch 400) Link/Activity LED
(Switch 800 or Switch 1600) not lit for a port
that has a connection.
There is a problem with this
connection. Check that you are using a
‘straight-through’ cable which is properly connected
at both ends, and is not damaged. Also check that
the equipment being connected to the Switch is
powered on, operating correctly and contains the
correct type of connection.
Alert LED continuously lit.
If the Alert LED is lit,
there is a problem with the network. Remove the
port connections one at a time, waiting a few
seconds between each port. If the Alert LED goes off,
there is either a network loop or an excessive amount
of broadcast traffic on that port connection:
Network loop — Examine your connections and
remove the loop. Each piece of equipment needs
only one connection to your Switch.
Excessive amounts of broadcast frames — Some
pieces of network equipment operate by sending
out broadcast frames regularly. Refer to the
documentation that accompanies the piece of
network equipment.
If the Alert LED is still lit after removing all of your
connections, there may be a problem with your
Switch. Power it off, wait about 5 seconds and then
power it on. If the Alert LED comes back on
continuously, contact your supplier.
Link between the Switch and an OfficeConnect
hub not working.
Check your connections; follow
the information given in the “Connecting
OfficeConnect Units to Your Switch” section. It is
likely that an MDI/MDIX Switch is incorrectly set on
the Switch or hub.
