Input/Output ports
Auxiliary-device (pointing device) port
The system board has one auxiliary-device port that supports a mouse or other
pointing device.
The following table shows the pin-number assignments for the auxiliary-device
connector on the rear of your server.
Ultra3 SCSI ports
Your server has an integrated dual-channel Ultra3 small computer system interface
(SCSI) controller. This controller supports two independent Ultra 160/m SCSI
channels. Both channels are internal. Each of these channels supports up to 15 SCSI
devices. In addition, this controller uses:
•
Double-transition clocking to achieve high transfer rates
•
Domain name validation to negotiate compatible data transfer speeds with each
device
•
Cyclic-redundancy checking (CRC), instead of the usual parity checking, to
significantly improve data reliability
•
An active terminator on the system board for SCSI bus termination
