Troubleshooting
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. See
page 5-1 for details.
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
An RPS is
connected but
may have
experienced a
fault.
Check the RPS unit to make sure it is plugged in to an active power source. If this is ok
but the LEDs are still blinking, the power supply in the RPS unit may have failed. Try
reversing R1 and R2 power cords. Also check the log files of the connected switch for
more information. This condition can also be caused by an RPS unit fan failure or and
over temperature condition. If necessary to resolve the problem, contact your ProCurve
authorized LAN dealer, or use the electronic support services from ProCurve to get
assistance. See the Customer Support/Warranty booklet for more information.
➒
An EPS is
connected but
the switch has
experienced a
fault.
Check the EPS unit to make sure it is plugged in to an active power source. If this is ok
but the LEDs are still blinking, the power supply in the EPS unit may have failed. Try
reversing EPS1 and EPS2 power cords. Also check the log files of the connected switch
for more information. This condition can also be caused by an RPS unit fan failure or and
over temperature condition. If necessary to resolve the problem, contact your ProCurve
authorized LAN dealer, or use the electronic support services from ProCurve to get
assistance. See the Customer Support/Warranty booklet for more information.
➓
Expansion yl
module is
plugged in but
has experienced

Check the rear of the switch. Check the module LEDs for indications. This will only occur
during an initialization self test.
