Wide Ultra-2 SCSI (LVD) ports
Your server has two Wide Ultra-2 SCSI (LVD) bus-master controllers on the I/O
function card; one supports internal devices and the other is connected to an
external connector for support of external devices. Each controller supports up to
15 SCSI devices. You can use the 68-pin, SCSI connectors for these controllers to
expand the capabilities of your server by attaching different types of SCSI devices,
such as drives or printers.
Table 11 shows the pin-number assignments for the 68-pin SCSI connectors.
