Dual USB ports Header (USB2)
This motherboard provides 4 USB connectors to connect USB devices, such
as mouse, keyboard, modem, printer, etc. There are two connectors on the
PC99 back panel. You can use proper cable to connect others USB connec-
tors to the back plane or front panel of chassis. By the way, if you want to
use the USB solution of CNR, please short the pin 2 & pin 3 of JP15/JP16.
ATX Power Connector (ATX 1)
This motherboard uses 24-pin Pentium 4 standard ATX power connector
and comes with an extra power connector for 5V/3.3V as shown below.
Please make sure you plug in the right direction.
A traditional ATX system should remain at power off stage when AC power
resumes from power failure. This design is inconvenient for a network
server or workstation, without an UPS, that needs to keep power-on. This
motherboard implements an AC Power Auto Recovery function to solve
this problem.
