Nu Technology LAN Port Indicators Integrated in LAN1 CN6 and LAN2 CN7, LED indication in LAN port

(5)ENUM# is connected to a BIOS programmable circuitry then connected to IRQ 3 or IRQ 9 according to the hardware configuration. There is a BIOS setting to Enable/Disable this ENUM# function. The default BIOS setting is Disabled and the factory default hardware configuration is IRQ 9. To support PICMG 2.1 Hot Swap for peripheral boards, backplane should bus all peripheral slots ENUM# together to system slot. And customer should enable ENUM# function in cPCI-6760DK/P5 BIOS setting. (When R283 and R284 are installed with 0-ohm resistors, ENUM# is routed through IRQ9. If R283, R284 are removed and R281 and R282 are installed with 0-ohm resistors, ENUM# is routed through IRQ3.)

(6)M66EN is tied to ground. PCI bus just can run in 33MHz.

(7)In backplane, BDSEL must tie to ground to enable “self-hot-swap” controller.

(8)IDSEL are tied to ground.
