Power LED is off. No power is received. Check the power cord connections for the
switch at the switch and the connected
device. Ensure all cables used are correct
and comply with Ethernet specifications.
Link LED is off or intermittent. Port connection is not
working. 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. Ensure all cables
used are correct and comply with Ethernet
specifications. See Appendix D. Check for a
defective adapter card, cable, or port by
testing them in an alternate environment
where all products are functioning.
File transfer is slow or
performance degradation is a
problem.
Half- or full-duplex setting
on the switch and the
connected device are not
the same.
Make sure the attached device is set to auto-
negotiate.
A segment or device is not
recognized as part of the
network.
One or more devices are
not properly connected, or
cabling does not meet
Ethernet guidelines.
Verify that the cabling is correct. Ensure all
connectors are securely positioned in the
required ports. Equipment may have been
accidentally disconnected.
