➐
The port may be
improperly
configured, or
the port may be in
a “blocking”
state by the
normal operation
of the Spanning
Tree, LACP, or
IGMP features.
Use the switch console to see if the port is part of a dynamic trunk (through the LACP
feature) or to see if Spanning Tree is enabled on the switch, and to see if the port may
have been put into a “blocking” state by those features. The show lacp command displays
the port status for the LACP feature; the show spanning-tree command displays the port
status for Spanning Tree.
Also check the Port Status screen using the show interfaces command to see if the port
has been configured as “disabled”.
Other switch features that may affect the port operation include VLANs and IGMP. Use
the switch console to see how the port is configured for these features.
For software troubleshooting tips, see the chapter “Troubleshooting” in the Management
and Configuration Guide, which is on the ProCurve Web site at www.procurve.com/
manuals.
Make sure also, the device at the other end of the connection is indicating a good link to
the switch. If it is not, the problem may be with the cabling between the devices or the
connectors on the cable.
➑
A power supply
has failed in a
multi-power
supply switch.
Check the back of the switch to see which power supply has failed. The failed power
supply LED will be blinking. Replace the failed power supply. Once the failed power supply
is removed the LEDs will return to normal. If only one supply is inserted, try power cycling
the switch. If the fault reoccurs, the power supply may need to be replaced. If there are
two power supplies inserted but only one is connected, to remove the fault either connect
power to the other supply or remove it.
➒
The switch has
overheated.
Check to ensure the fans are functioning correctly.
