AAA-130U2 Series Installation and Hardware Guide

Internal Ultra2 SCSI Connector (68-pin)

Use the internal Ultra2 SCSI connector to connect internal Ultra2

and Ultra SCSI devices. The AAA-131U2 has one internal Ultra2

SCSI connector (Channel A); and the AAA-133U2 has three

(Channels A, B, and C).

Note:

We recommend keeping Ultra2 devices on separate

channels from non-Ultra2 devices. Peak transfer rates on

Ultra2 channels are 80 MBytes/sec. Connecting a non-

Ultra2 device to an Ultra2 SCSI channel limits the entire

channel to lower performance levels (up to 40 MBytes/sec).

To connect internal Ultra2 SCSI devices, a 68-pin internal Ultra2

SCSI cable, similar to the one shown in Figure 2-7, is required.

Follow these steps to connect your internal Ultra2 devices:

Locate the 68-pin internal Ultra2 SCSI cable.
