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. 18 Intel Server Board SE7501HG2 Product Guide
