SCSI Controller
The embedded Adaptec AIC-7902 dual function SCSI controller provides Ultra320 (LVDS),
(Ultra 4), and Ultra wide (SE) SCSI interfaces as two independent PCI functions.
The Intel SE7501HG2 baseboard provides active terminators, termination voltage, resetable fuse,
and protection diode for both SCSI channels.
IDE Controller
The system includes a dual-channel enhanced IDE 32-bit interface controller for intelligent disk
drives with disk controller electronics onboard. The controller has both primary and secondary
connectors on the system board, each of which supports a master and a slave device.
The device supports:
• PIO, ATA-100 Synchronous DMA, and bus master IDE transfer modes
• Ultra DMA 33/66/100 synchronous DMA transfers
• Master/slave IDE modes
• Up to four devices
USB Interface
The server board SE7501HG2 provides three external USB connectors on the rear I/O panel.
Revision 1.1 of the USB Specification defines the external connectors. An additional USB
controller is supported internally through a 10-pin header on the server board that can be cabled to
two additional USB ports on the front panel board. All five ports function identically and with the
same bandwidth.
