Chapter 1: Introduction One Fast UART 16550 compatible serial port and a Mellanox Connect-X MT25408 20Gb/s Infi niBand controller are located on the serverboard. The color-coded I/O ports include one COM port (an additional COM header is located on the serverboard), a VGA (monitor) port, two USB 2.0 ports (additional 2+2 internal USB headers are included on the serverboard) and two gigabit Ethernet ports. Onboard Controllers/Ports Graphics Controller The H8DMT-F/H8DMT-IBXF features an integrated Windbond WPCM450 BMC graphics controller.
Other Features Other onboard features that promote system health include onboard voltage monitors, a chassis intrusion header, auto-switching voltage regulators, chassis and CPU overheat sensors, virus protection and BIOS rescue. 1-3 Server Chassis Features The following is a general outline of the main features of the SC827 server chassis. System Power Each SC827 chassis model includes a high-effi ciency 80 Plus Gold certifi ed power supply, rated at 1200 Watts plus one redundant backup power supply. In the unlikely event your power supply fails, replacement is simple and can be accomplished without tools.
SATA Subsystem The SC827 supports up to twelve 3.5" hot-swap SATA drives in trays (3 for each node). These drives are hot-swappable units and are connected to a backplane that provides power and control. Note: The operating system you use must have RAID support to enable the hot- swap capability of the drives. 1-3
