8.16 Keyboard and Mouse Connector

Two stacked PS/2* ports are provided in a single housing for keyboard and mouse support.
Although the board set supports swapping of these connections, the top port is color-coded
green to designate mouse support, and the bottom port is color-coded violet to designate
keyboard support. The following table details the pin-out of the PS/2 connectors.

8.17 Fan Headers
The Intel® Server Board SE7520AF2 provides eight fan headers: two for CPU fans and six for
system fans. The CPU fans are labeled "CPU1_FAN" and "CPU2_FAN". The CPU fan
connectors only support steady 12-volt power.
The system fans are labeled "SYS FAN_1" through "SYS FAN_6". All system fan connectors
have variable speed control and are capable of supporting variable speed fans. "SYS FAN_1"
and "SYS FAN_2" are enabled via a 3-pin + 2-pin header; "SYS FAN_3" and SYS FAN_4" are
enabled via a 6-pin header; and "SYS FAN_5" and "SYS FAN_6" are enabled via a 3-pin
header.
