13. CPU, Front, and Rear fan connectors
(3-pin CPU_FAN1/2, FRONT_FAN1/2, REAR_FAN1/2)
The fan connectors on this motherboard support various server
configurations. Use the rear fan connectors if you intend to install the
motherboard in a tower/pedestal chassis. Use the front fan connectors
when using a rackmount configuration.
The fan connectors support cooling fans of 350 mA ~ 740 mA (8.88 W
max.) or a total of 1 A ~ 2.22 A (26.64 W max.) at +12 V. Connect the
fan cables to the fan connectors on the motherboard, making sure that
the black wire of each cable matches the ground pin of the connector.
PSCH-SR Fan Connectors
Do not forget to connect the fan cables to the fan connectors. Lack of
sufficient air flow within the system may damage the motherboard
components. These are not jumpers! DO NOT place jumper caps on
the fan connectors!
14. Serial connector (10-1 pin COM2 for management use)
This connector accommodates a server management card using the
serial interface.
PSCH-SR Serial COM2 Bracket
Since this connector is dedicated for server management, you must
use a null modem cable to make the connector operational.
