KVM Over Wireless

Anytime the user selects Tools Link Preference > OS owns Wireless, control of the wireless link is transferred from the Intel Management Engine to the operating system. (ME gains control of the wireless link anytime a shutdown or reboot command is selected from Tools Power Control.)

Whenever ME is given control of the wireless link (Link Preference), a timeout value is supplied that indicates how long ME is to maintain control of the wireless link, after which, control is given back to the OS. For example, a user selects Reboot To OS to reboot the client operating system.

In order to maintain the KVM link, ME is first given control of the wireless link. The timeout is set by default to 10 minutes to provide ample time for the system to complete the reboot process. ME will maintain control even after the OS has rebooted if the reboot completes in under 10 minutes. To give control back to the OS immediately, the user must select Tools > Link Preference > OS owns Wireless. In that case, the KVM connection is lost during the transfer process. To re-establish the connection, the user must select Connection > Start. Also note that when control of the wireless link is automatically reverted as a result of the Link Preference Timeout expiring, there is no loss of connectivity. There are individual timeout values for each shutdown/reboot operation (defined in KVM View app.config settings) that can be configured externally:

• LPTImeoutRebootToOS
• LPTimeoutRebootToBIOS
• LPTimeoutRebootToDiagnostics
• LPTimeoutRebootWithIDER
• LPTimeoutShutdown
