3.8 Video
A single ATI* Radeon* 7000 video controller provides the on-board video interface. The ATI
Radeon 7000 features the following technologies:
2D/3D video accelerator
Dual DAC for integrated, cost-effective multi-panel support
Resolutions from VGA up to UXGA (1600x1200)
16MB SDRAM video memory
32-bit/33MHz PCI host interface
Using the default operating system video driver options, the VGA signal is mirrored between the
rear panel and the front panel connector. This design consideration was made to facilitate user
debug of an operating system hard failure. When the system is in a failure state a portable
monitor can be attached to the front of the system to determine root cause. Since this is an
enterprise server, Intel has not validated the video driver configured with the front panel I/O
board VGA connector in a non-mirrored, extended desktop, state.
3.9 USB 2.0
The ICH5 provides four USB 2.0 interfaces with one internal connector on the Intel
®
Server
Board Set SE8500HW4 Mainboard, a dual-stack USB connector on the rear panel, and one
interface routed to the front panel connector.
3.10 Serial
The SIO provides two RS232 serial communication ports (COM1 and COM2). COM1 is
provided through DB9 connector on the rear panel of the Intel
®
Server Board Set SE8500HW4
Mainboard while COM2 is internal to the chassis and available as an unshielded 9-pin header (2
x 5, with pin 10 removed for keying). COM1 is available as an Emergency Management Port
(EMP) for remote server management, and when used in this mode, it is unavailable to the
BIOS/operating system. When server management is setup for Serial Over LAN (SOL) remote
server management, COM2 is unavailable to the BIOS/operating system.
