Chapter 8 Common Administrative Tasks
Shutting down your appliance exits Cisco IronPort AsyncOS, which allows you to safely power down
the appliance. You may restart the appliance at a later time without losing any messages in the delivery
queue. You must enter a delay for the appliance to shutdown. The default delay is thirty (30) seconds.
Cisco IronPort AsyncOS allows open connections to complete during the delay, after which it forcefully
closes open connections.

Placing the Cisco IronPort Appliance into a Maintenance State
If you want to perform system maintenance, the Cisco IronPort appliance should be placed into the
offline state. The suspend and offline commands put the Cisco IronPort AsyncOS operating into offline
state. The offline state is characterized by the following:
Inbound email connections are not accepted.
Outbound email delivery is halted.
Log transfers are halted.
The CLI remains accessible.
You must enter a delay for the appliance to enter the offline state. The default delay is thirty (30) seconds.
Cisco IronPort AsyncOS allows open connections to complete during the delay, after which it forcefully
closes open connections. If there are no open connections, the offline state commences immediately.
