HeartBeat

What is HeartBeat?

HeartBeat is round-the-clock hardware safeguard. It has a micro-controller that overlooks the whole hardware platform to ensure continuous operation even in the event of critical breakdown.

In the event the server fails, it will send request-for-help signal via its built-in digital I/O, which can be connected to Central Alarm Management System.

In what event will the HeartBeat react?

Event	HeartBeat's action
Unauthorized Shutdown	Reboot the ECA
Unauthorized Power Unplug	Produce beep tone
ECA not responding	Forces system reboot after 2 minutes
Blue screen of death (BSOD)	Forces reboot after 2 minutes
