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.
