Voltage monitors connected to power indicator LEDs monitor the regulated power on the
board (see Figure 2-23). The indicator LEDs illuminate red if a regulated supply voltage is
out of spec, and illuminate green if the regulated supply voltage is nominal. Each
regulated supply voltage has a corresponding test point located near its indicator LED. See
the ML410 schematics and the associated data sheets for more information.
In addition to the voltage monitors, the ML410 employs a SMBus device, LM87, which
samples several of the same supply voltages when accessed over the System Management
Bus. See the "IIC/SMBus Interface"
