The following table lists symptoms, possible causes, and possible solutions for hardware problems that
might occur.
Table 6. Troubleshooting chart
Symptom
Power LED is off.
Both ports LEDs are off when
the port is connected to a
powered-on device.
File transfer is slow or
performance is degraded.
A segment or device is not
recognized as part of the
network.
One or more port LEDs are
blinking continuously and the
network is disabled.
Possible Cause
Power is not supplied to the switch.
Port connection is not working.
One possible cause is that a
broadcast storm occurred and that a
network loop (redundant path) was
created.
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 power cable connections at the
switch and the power source.
Make sure that all cables are used correctly and
comply with the Ethernet specifications.
Check the crimp on the connectors and make
sure that the plug is properly inserted and
locked into the port at both the switch 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.
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.
Break the loop by making sure that only one
path exists from any networked device to any
other networked device.
