Chapter 10 Troubleshooting
Soft reset: Press Reset button for less
than five seconds
• Resets management module "A" after
a 5-10 second delay for orderly
shutdown.
• Failover occurs. Module "A" becomes
the Standby after it comes back up.
• Module "B" (the former Standby
management module) becomes the
new Active management module and
maintains switch operation.
• If there is no Standby management
module installed, or if the installed
Standby module is inoperative, then
the switch goes down while module
"A" completes the reset process and
resumes operation as the Active
management module.
• Resets management module "B"
during a 5-10 second reset delay for
orderly shutdown.
• The switch remains up and running.
• Management module "B" returns to
the Standby role when it completes its
reset cycle.
• No effect on the Active management
module (Module "A").
NOTE: If a condition that
causes a failover occurs
while Module "B" is still in its
reset cycle, a full chassis
restart results.
Hard reset: Press Reset button for five
seconds or more
• Immediately resets management
module "A". There is no shutdown
process. This action can result in a loss
of data that was currently being
processed in module "A".
• Management module "B" does not
reset; becomes the new Active
management module.
• If there is no second module installed,
or if the installed second module is
inoperative, then the switch goes
down while management module "A"
completes the reset process and
resumes operation.
• Immediately resets management
module B. There is no orderly
shutdown process.
• Management module "B" resumes as
the Standby management module
after the reset concludes.
• No effect on the Active management
module (Module "A").
