Components 17
Soft power connector
The soft power connector provides for the connection of a switch that
powers up or powers down the server from a standby state. This feature is
not implemented on this system.
Drive controllers and connectors
There are several controllers and connectors for the control of the various
drives that are or can be installed in the system.
Hard drive controller and connectors
This is an integrated dual-channel Ultra-DMA PCI/IDE interface with two
IDE connectors capable of controlling up to four IDE devices and
supporting PIO Modes 0-4. Ultra-DMA provides faster access to IDE
devices that are Ultra-DMA compliant while maintaining support for IDE
devices that do not support the Ultra-DMA specification.
Floppy controller and connector
The floppy drive controller and connector on the system board can support
up to two floppy drives of 1.44-MB and 2.88-MB formats.
SCSI controller and connectors
This integrated dual channel Adaptec
®
AIC™-7890 SCSI controller is a
high-performance, PnP compliant, single-chip PCI local bus-to-Ultra2
SCSI master host adapter. Its advanced SCSI I/O cell technology ensures
data integrity for higher I/O bandwidth requirements with data rates of
40-MB/sec in Ultra mode and 80-MB/sec in Ultra2 mode.
Additional features:
• Dual LVD 16-bit (68-pin) PCI-to-Wide Ultra2 SCSI connectors
• Full 32-bit PCI bus master implementation maximizing data
transfer on PCI local bus at 133-MB/sec data bursts
