LAN1/2 (Ethernet Ports)
Two Gigabit Ethernet ports (designated
LAN1 and LAN2) are located beside the
VGA port. Additionally, there is a dedicated
LAN poor for IPMI above the two rear USB
ports. These Ethernet ports accept RJ45
type cables.
Universal Serial Bus Ports
Six Universal Serial Bus ports (USB 2.0) are
located beside the LAN ports. Two additional
Type A ports (USB4/5) are included on the
motherboard near the PCI Slot 1. See the
table on the right for pin defi nitions.
USB Headers
Two USB 2.0 headers (USB2/3) are also
included on the motherboard. These may
be connected to provide front side access. A
USB cable (not included) is needed for the
connection. See the table on the right for
pin defi nitions.
Fan Headers
This motherboard has eight fan headers
(Fan1 to Fan8). These 4-pin fans headers
are backward compatible with 3-pin fans.
However, fan speed control is available for
4-pin fans only. The fan speeds are con-
trolled by the BIOS. See the table on the right
for pin defi nitions
