Scsi Controller; Video Controller; Peripheral Controller; System Board Management Controller (Bmc) - NEC Express5800 series User Manual

!
Descriptor ring management architecture optimized to deliver both high performance
and PCI/PCI-X bus efficiency
!
Low power +3.3 V device
!
IP and TCP/UDP checksum off-loading.

SCSI Controller

The baseboard includes an embedded Adaptec 7899 SCSI controller, which contains
two independent SCSI channels. You can disable the SCSI controller in BIOS Setup.
Both channels support 16-bit SE or LVD SCSI operations at the following speeds:
!
Ultra160 (160 MB/sec)
!
Ultra2 (80 MB/sec)
!
Ultra Wide SE (40 MB/sec)
The baseboard provides active terminators, termination voltage, resettable fuses, and
protection diodes for both SCSI channels. You can disable the onboard terminators in
BIOS Setup.

Video Controller

The baseboard incorporates an ATI RAGE XL PCI graphics accelerator with 4 MB of
video SDRAM that supports all standard IBM VGA modes. The embedded SVGA
video subsystem supports:
!
Pixel resolutions up to 1600 x 1200 under 2D and 1024 x 768 under 3D
!
CRT and LCD monitors up to 100 Hz vertical refresh rate
The baseboard supports disabling of the onboard video through BIOS Setup or when a
plug-in video card is installed in any of the PCI slots.

Peripheral Controller

The advanced integrated peripheral controller supports two serial ports, two universal
serial bus ports, one parallel port, diskette drive, PS/2-compatible keyboard and mouse,
and integrated Real Time Clock (RTC). The system provides the connector interface for
each port.

System Board Management Controller (BMC)

Server management is concentrated in the System Board Management Controller
(BMC). The BMC and associated circuitry are powered from a 5Vdc standby voltage,
which remains active when system power is switched off, but the ac power source is
still on and connected.
The BMC supports the Management Workstation Application (MWA), which allows
remote server management via a modem, LAN, or direct connection to a manager
system. Events monitored by the manager system include over-temperature and over-
voltage conditions, fan failure, or chassis intrusion.
