Wakeup Events 
The SE7501HG2 system supports several wakeup events. 
 
Wake on LAN 
Wake on LAN allows system power to be activated through the network.  If the system is in the S1 
or S4 state, it can be turned on remotely by sending a specific packet to the remote system.  The 
system contains a configuration option that allows the on-board NICs to be enabled to wake the 
system from a S4 or S5 sleep state, even if the operating system disabled Wake on LAN when it 
powered down the system.  This provides an option for users who want to use standard, but 
non-secure, Wake on LAN capability for operations such as after-hours maintenance.  Server 
management features provide a secure system power-up, plus the ability to provide BIOS boot 
option. 
Wake on Ring 
Wake on Ring allows system power to be activated through the Serial ports when this option is 
enabled in Setup.  If the system is in the S1 or S4 state, it can be turned on remotely by the Ring 
Indicate RI signals from the serial ports.

NOTE 
Wake on Ring is disabled in Serial B if this port is used as the Emergency 
Management Port. 
 
Wake on RTC Alarm 
Wake on RTC alarm allows system power to be activated through a real-time clock alarm when this 
option is enabled in Setup.  If the system is in the S1 or S4 state, it can be turned on by an RTC 
trigger event.
