2-20 Chapter 2: Hardware information
3. USB device wake-up (3-pin USBPW12, USBPW34, USBPW56,
USBPW78)
Set these jumpers to +5V to wake up the computer from S1 sleep
mode (CPU stopped, DRAM refreshed, system running in low power
mode) using the connected USB devices. Set to +5VSB to wake up
from S4 sleep mode (no power to CPU and DRAM, power supply in
reduced power mode).
• The USB device wake-up feature requires a power supply that can
provide 500mA on the +5VSB lead for each USB port; otherwise, the
system would not power up.
• The total current consumed must NOT exceed the power supply
capability (+5VSB) whether under normal condition or in sleep mode.
2. CPU fan pin selection (3-pin FM_CPU1, FM_CPU2)
These jumpers allow you to connect either a 3-pin or a 4-pin fan cable
plug to the CPU fan connectors (CPU_FAN1, CPU_FAN2). Set these
jumpers to pins 1-2 if you are using a 3-pin fan cable plug, or to pins
2-3 if you are using a 4-pin plug.
