Rebooting, Resetting, and Power Cycling

Reboot

Rebooting the Acme Packet 4900 shuts down the system in an orderly fashion and then automatically restarts it. The operating system gracefully shuts down as processes are terminated and the file system is stopped. While the system and its processes are stopped, all call processing is immediately halted. You may therefore wish to perform tasks that call for a reboot during off-peak maintenance hours.

Rebooting the Acme Packet 4900 is required every time you upgrade with a new version of the software.

Save your configurations before rebooting. Refer to the Maintenance and Troubleshooting Guide for a full explanation of this procedure. The save-config command is used to save the configuration in the example below.

To reboot:

Type save-config to save any configuration changes you made.

ACMEPACKET# save-config
 Save-Config received, processing.
 waiting 1200 for request to finish

Type reboot.

Power Cycling

Power cycling the Acme Packet 4900 is the process of turning the chassis off and then on again. When power cycling, it is imperative that you wait at least 20 seconds between power down and power up to ensure that all components are completely powered down before restarting the system.
