> # Allowing the Host to Move the Switch Offline

> By default, hosts are allowed to move the switch to an offline state. To do this, the host sends a "Set offline" command (x'FD') to the CUP.

> ## Detailed Steps

> To allow the host (mainframe) to move the switch to an offline state, follow these steps:

> 1. Choose VSAN > FICON.

> You see a list of switches under the Control tab in the Information pane.

> 2. Click the VSANs tab.

> You see the FICON VSAN configuration information in the Information pane.

> 3. Check the Host Can Offline Sw check box to allow the mainframe to move a switch to the offline state.
> 4. Check the Host Can Sync Time check box to allow the mainframe to set the system time on the switch.
> 5. Click the Apply Changes icon to save the changes.
