Appendix E: Introduce The Alert on LAN
The primary functions of the Alert on LAN *2 ASIC are to provide an interface to the 82559 and
to the system monitoring critical system parameters and conditions, such as supply voltage
detected, cover tamper, over temperature, link loss, and processor missing intrusion. If such a
condition is detected, the Alert on LAN ASIC *2 transmits this information to the 82559. In
response, the 82559 transmits alert ("SOS") packets to the remote console.
The Alert on LAN *2 ASIC transmits periodic presence packets (heartbeat) to the remote
console. It support receiving specially filtered packets, in order to perform various Advanced
Power Management modes(such as power-up, power-down and reset), And we very expected
these operations to be available when software is unable to perform these functions (such as
during a low power state or boot-up or when the operating system becomes inoperable)but are
not precluded from running in the working state.
