Taking the Security Management Appliance Out of Service

If you want to take the appliance offline, for example to perform system maintenance, use one of the following commands:


Command	Description	Persistence
`suspend`	Suspends transfer of quarantined messages from the Email Security appliance to the Security Management appliance. Suspends delivery of messages released from quarantines. Inbound email connections are not accepted. Outbound email delivery is halted. Log transfers are halted. The CLI remains accessible.	Persists after reboot.
`suspendtransfers`	Suspends transfer of reporting and tracking data from managed email and web security appliances to the content security management appliance. This command also suspends receiving of quarantined messages from Email Security appliances. Use this command when preparing to bring a backup appliance into service as the primary appliance.	Persists after reboot.

You must enter a delay for the appliance when using these commands. The default delay is 30 seconds. AsyncOS allows open connections to complete during the delay, after which it forcefully closes open connections. If there are no open connections, service is suspended immediately.

To re-activate services that were halted by the suspend or suspendtransfers commands, use the resume or resumetransfers commands, respectively.

To determine the current online/suspended status of the management appliance, select Management Appliance > System Administration > Shutdown/Reboot in the web interface.
