1-11 HARDWARE MONITOR
The optional hardware monitor subsystem provides low- cost
instrumentation capabilities. The features of the hardware monitor
subsystem include:
Ø An integrated ambient temperature sensor
Ø Fan speed sensors, which monitor the fan 1 and fan 2 connectors
Ø 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
Wa ke on LAN technology enables remote wakeup of the computer
through a network. Wake on LAN technology requires a PCI add- in
net work interface card (NIC) with remote wakeup capabilities. The remote
wakeup connector on the NIC must be connected to the onboard Wake on
LAN technology connector. The NIC monitors network traffic at the MII
interface; upon detecting a Magic Packet, the NIC asserts a wakeup signal
that powers up the computer. To access this feature uses the Wa ke on LAN
technology connector.
*
CAUTION
For Wake on LAN, the 5-V standby line for the power supply must be
capable of delivering +5V ±5 % at 720 mA. Failure to provide adequate
standby current when implementing Wake on LAN can damage the power
supply.
