Troubleshooting Chart

The following table lists symptoms, causes, and solutions for possible problems.
Table 6. Troubleshooting chart
Symptom
Power LED is off.
PoE Max LED is lit or
blinking (GSS108EPP
switch only)
Combined Speed and
Activity LED is off when
the port is connected to
a device.
File transfer is slow or
performance is
degraded.
A segment or device is
not recognized as part
of the network.
Combined Speed and
Activity LED is blinking
continuously on all
connected ports and
the network is disabled.
Cause
No power is received.
• Solid amber. Less than 7W of
PoE power is available.
• Blinking amber. The PoE Max
LED was active in the previous
two minutes.
Port connection is not working.
One possible cause:
A broadcast storm occurred and a
network loop (redundant path) was
created.
Another possible cause:
Half-duplex or full-duplex setting on
the switch and the connected
device are not the same.
One or more devices are not
properly connected, or cabling does
not meet Ethernet guidelines.
A network loop (redundant path)
was created.
Troubleshooting
Solution
• Check the power cable connections at the
switch and the power source.
• Ensure that all cables are used correctly and
comply with the Ethernet specifications.
For information about the maximum PoE power
budget , see Connect PoE Devices to the
GSS108EPP Switch
• 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 or cable by testing
them in an alternate environment where all
products are functioning.
Break the loop by ensuring that only one path
exists from any networked device to any other
networked device.
Make sure that the attached device is configured
for autonegotiation.
• 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.
