3.6.1 Integrated BMC Embedded LAN Channel
The Integrated BMC hardware includes two dedicated 10/100 network interfaces. These
interfaces are not shared with the host system. At any time, only one dedicated interface may
be enabled for management traffic. The default active interface is the NIC 1 port.
For these channels, support can be enabled for IPMI-over-LAN and DHCP.
For security reasons, embedded LAN channels have the following default settings:
 IP Address: Static.
 All users disabled.
3.6.2 Floppy Disk Controller
The server board does not support a floppy disk controller interface. However, the system BIOS
recognizes USB floppy devices.
3.6.3 Keyboard and Mouse Support
The server board does not support PS/2 interface keyboards and mice. However, the system
BIOS recognizes USB specification-compliant keyboard and mice.
3.6.4 Wake-up Control
The super I/O contains functionality that allows various events to power on and power off
the system.
3.7 Video Support
The server board includes a video controller in an on-board Server Engines* Integrated
Baseboard Management Controller along with 8 MB of video DDR2 SDRAM. The SVGA
subsystem supports a variety of modes, up to 1600 x 1200 resolution in 8/16 bpp modes under
2D. It also supports both CRT and LCD monitors up to 85 Hz vertical refresh rate.
The video is accessed using a standard 15-pin VGA connector (J8A1) found on the back edge
of the server board. The on-board video controller can be disabled using the BIOS Setup utility
or when an add-in video card is detected. The system BIOS provides the option for dual-video
operation when an add-in video card is configured in the system.
3.7.1 Video Modes
The integrated video controller supports all standard IBM VGA modes. The following table
shows the 2D modes supported for both CRT and LCD:
