Resetting the Appliance
Step 1 Log in to the CLI.
Step 2 Ping the address you are interested in. The count is the number of echo requests to send. If you do not
specify a number, 4 requests are sent. The range is 1 to 10,000.

Resetting the Appliance
Use the reset [powerdown] command to shut down the applications running on the appliance and to
reboot the appliance. You can include the powerdown option to power off the appliance, if possible, or
to have the appliance left in a state where the power can be turned off.
Shutdown (stopping the applications) begins immediately after you execute the command. Shutdown can
take a while, and you can still access CLI commands while it is taking place, but the session is terminated
without warning.
