Hardware troubleshooting chart

The following table lists symptoms, possible causes, and possible solutions for problems
that might occur.
Table 3. Troubleshooting chart
Symptom
The Power LED and LAN1 LED
on the AirBridge are off
The LAN2 LED on the
AirBridge is off although the
port is connected to a
powered-on device.
A file transfer is slow or
performance is degraded.
A segment or device at a
detached site is not
recognized as part of the
network.
The network is disabled. On a
switch that is connected to an
AirBridge, the port LEDs for
all connected ports might be
blinking continuously.
Hardware troubleshooting
Possible Cause
Power is not supplied to the
AirBridge
The port connection is not
working.
One possible cause is that a
network loop (redundant
path) was created and that a
broadcast storm occurred.
One or more devices are not
properly connected, or
cabling does not meet
Ethernet guidelines.
A network loop (redundant
path) was created.

Possible Solution
• Check the Ethernet cable connection at the
LAN1 port on the AirBridge and the PoE port
on the power adapter.
• Check the cable connection from the power
adapter to the electrical outlet and make sure
that the outlet is providing power.
• Check the crimp on the connectors and make
sure that the plug is properly inserted and
locked into the port at both the AirBridge and
the connecting device.
• Make sure that all cables are used correctly and
comply with the Ethernet specifications.
• Check for a defective port, cable, or module
by testing them in an alternate environment
where all products are functioning.
Break the loop by making sure that only one path
exists from any networked device to any other
networked device. After you connect to the
AirBridge local browser UI, you can configure the
Spanning Tree Protocol (STP) to prevent network
loops.
• Verify that the cabling is correct.
• Make sure that all connectors are securely
positioned in the required ports. It is possible
that equipment was accidentally disconnected.
