Basic Troubleshooting Tips
Troubleshooting
■ Check the port configuration. A port on your switch may not be
operating as you expect because it has been put into a “blocking” state by
Spanning Tree, GVRP (automatic VLANs), or LACP (automatic trunking).
(Note that the normal operation of the Spanning Tree, GVRP, and LACP
features may put the port in a blocking state.) Or, the port just may have
been configured as disabled through software.
Use the switch console to determine the port’s configuration and verify
that there is not an improper or undesired configuration of any of the
switch features that may be affecting the port. For more information, see
the Management and Configuration Guide, which is on the ProCurve
Web site at www.procurve.com/manuals.
■ Recover from a lost manager password. If you cannot start a console
session at the manager level because of a lost Manager password, you can
clear all passwords and user names by pressing and holding the Clear
button on the switch for a full second.
■ Receive a log message for incorrect air flow. The direction of air flow
in a 6600 Switch is set by default from the power to the port side. When
you mount a 6600 Switch with the port side or power side facing the cold
aisle, you must ensure that the air flow direction is from the cold side to
the hot side of the aisle. If necessary, reverse the direction of the fans to
provide adequate switch cooling as described in “Reverse the air flow” on
page 2-8.
If you reverse the direction of the fans, be sure to record the preferred air-
flow direction for a 6600 Switch by using the system fan-pref-airflow-dir
{ port-to-power | power-to-port } CLI command at the global configuration
level. A Syslog message is then generated if the fan tray is installed in the
wrong direction in the future.
For more information on possible network problems and their solutions, refer
to the technical note “Troubleshooting LAN Performance and Intermittent
Connectivity Problems”, which can be found on the ProCurve Web site,
www.procurve.com/library, under “T” in the A-Z Index section.
