BAM8270 Manual
BIOS (FLASH)
The BAM8270 board uses an InsydeH20® UEFI BIOS from Insyde. The BIOS features built-in advanced
CMOS setup for system parameters, peripheral management for configuring on-board peripherals and
other system parameters. The BIOS resides in two 512Mb Macronix MX25L51245G SPI Serial EEPROMs.
Should you have a custom BIOS request please contact us for assistance.
ETHERNET INTERFACES
The BAM8270 supports four Ethernet interfaces using two physical ports.
•
The interfaces are implemented using two Intel® i350 Dual Gigabit Ethernet Controllers.
•
Each physical port is shared with the BMC via NC-SI (network controller sideband interface).
All interfaces support 10/100/1000Base-T Ethernet modes and are compliant with the IEEE 802.3
Specification.
The main components of the Ethernet interfaces are:
Intel® i350 controllers for 10/100/1000-Mb/s Ethernet.
Integrated RJ-45/Magnetics module connectors on the motherboard's I/O bracket for direct
connection to the network. The connectors require category 5 (CAT5) unshielded twisted-pair (UTP)
2-pair cables for a 100-Mb/s network connection or category3 (CAT3) or higher UTP 2-pair cables
for a 10-Mb/s network connection. Category 5e (CAT5e) or higher UTP 2-pair cables are
recommended for a 1000-Mb/s (Gigabit) network connection.
MAC addresses on the board are mapped to the interfaces following the table below:
MAC1
I350 Gbit – Top Port
MAC2
I350 Gbit – Bottom Port
MAC3
BMC – Top Port
MAC4
BMC – Bottom Port
Link status and activity LEDs on the I/O bracket for status indication (See Ethernet LEDs and
Connectors later in this chapter.)
SATA INTERFACES
There are 6 Serial ATA (SATA) interfaces available on the BAM8270 motherboard. All of the SATA
interfaces are driven with a built-in SATA controller from the Intel® C621 PCH. The board’s SATA ports
can support up to six independent storage devices such as hard disks, solid state drives, and CD/DVD-
RW devices at data rates up to 600 MB per second on each port. The board’s PCH features the Intel ®
Rapid Storage Systems functionality, which allows a third BIOS-selectable SATA controller configuration
that enables RAID array configurations capable of supporting RAID 0, 1, and 10 implementations.
