refer to the list of suggested solutions below.
An expansion module is installed and the unit will not power up
Ensure that the expansion module is fully seated in the slot and the
connectors are engaged so that the securing screws can be tightened.
A fan failure warning message is received
Your Switch has a fan monitoring system that will generate fan failure
warning messages. Fan failure could potentially reduce the lifetime of the
Switch. The monitoring system polls the fan status at periodic intervals
while the unit is powered up.
Should one fan failure occur in the Switch, a warning message will be
generated in the following ways:
■
RMON Email Notification
— If configured, you will receive
notification of the fan failure via email, SMS (Short Message Service),
or pager.
■
RMON Trap
— If configured, an RMON trap is generated and sent to
the management workstation.
For further information about RMON, refer to “Chapter 7: Status
Monitoring and Statistics” in the Switch Implementation Guide supplied
in PDF format on the CD-ROM that accompanies the Switch.
If more than one fan fails in the Switch, a warning message will be
generated by RMON Email Notification, RMON Trap and also in the
following ways:
■
Command Line Interface
— An indication of a general hardware
failure is provided through the Top level menu displayed when logging
on to the CLI. For more detailed information about the failure select
the
system summary
command.
■
Web interface
— An indication of fan failure is provided through the
Device Summary table for the specific unit. In addition all Summary
tables turn red to indicate the fan failure.
