PROBLEM SOLVING
The 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 network equipment is powered on.
■ Power each piece of network equipment off, wait about
5 seconds and then power each one 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 another OfficeConnect
power adapter. Do not use any other power adapter
with the Switch.
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 LED's to illuminate. The port status LED
should turn Green or Yellow for each port that is
connected. The Duplex LED may or may not illuminate.
Please refer to pages 5, 6 and 7 'Creating your Network' for
a full description of the LED's.
lf the Port Status LED has not lit after several seconds,
ensure the connected device is powered, the TP cable is not
damaged and that it is correctly inserted at both ends.
You may find a TP cable works when connected to the
Switch but doesn't if it is disconnected from the Switch and
connected to a different piece of equipment. This may be
due to the advanced automatic MDI / MDIX feature of the
Switch that the other equipment may not have.
Alert LED continuously lit. Power down the Switch and
disconnect all network connections. Wait about 5 seconds
and power the Switch back up. If the Alert LED is
continuously lit it can mean there is a problem with your
Switch. The 5, 8 and 16 port Switches will also turn the
Alert LED on if there is a high level of broadcast traffic or
the Switch detects a network loop. To determine whether
this is the case, connect one network connection at a time,
waiting a few seconds between each.
