Fan Headers

The H8DA3-2/H8DAi-2 has eight fan

headers, which are designated FAN1

through FAN8. Fans are Pulse Width

Modulated (PWM) and their speed is

controlled via Thermal Management

with a BIOS setting. See the table on

the right for pin deﬁ nitions.

Note: when using active heatsinks

(those with fans), connect the heatsink

fan for CPU1 to the FAN7 header and

the heatsink fan for CPU2 to the FAN8

header.

Serial Ports

The COM1 and COM2 serial ports are

located under the parallel port. Refer

to Figure 2-3 for locations and the

table on the right for pin deﬁ nitions.

LAN1/2 (Ethernet Ports)

Two Gigabit Ethernet ports (desig-

nated LAN1 and LAN2) are located

beside the COM2 port. These Ether-

net ports accept RJ45 type cables.

Note: NC indicates no connection.
