1-11 HARDWARE MONITOR
The optional hardware monitor subsystem provides low-cost
instrumentation capabilities. The features of the hardware monitor
subsystem include:
An integrated ambient temperature sensor
Fan speed sensors, which monitor the fan 1 and fan 2 connector.
Power supply voltage monitoring to detect levels above or below
acceptable values
When suggested ratings for temperature, fan speed, or voltage are exceeded,
an interrupt is activated. The hardware monitor component connects to the
SMBus.
1-12 WAKE ON LAN TECHNOLOGY
Wake on LAN technology enables remote wakeup of the computer through
a network. Wake on LAN technology requires a PCI add-in network
interface card (NIC) with remote wakeup capabilities. The remote wakeup
connector on the NIC must be connected to the onboard Wake on LAN
connector. The NIC monitors network traffic at the Ethernet interface; upon
detecting a Magic Packet, the NIC asserts a wakeup signal that powers up
the computer. This feature uses the Wake on LAN connector.
CAUTION
For Wake on LAN, the 5-V standby line for the power supply must be
capable of deli5V ±5 % at 720 mA. Failure to provide adequate
standby current when implementing Wake on LAN can damage the power
supply.
