Intel S875WP1-E manual Connecting the IDE Cable

Connecting the IDE Cable

The Intel® boxed server board package includes a 40-contact, 80-conductor IDE cable. This cable is capable of connecting two drives to the server board. The cable supports Ultra ATA/100/66 and Ultra ATA/100 transfer protocols and is backward-compatible with drives using slower IDE transfer protocols.

✏NOTE

ATA-66/100 cables are backward compatible with drives using slower IDE transfer protocols. If an ATA-66/100 disk drive and a disk drive using any other IDE transfer protocol are attached to the same cable, the maximum transfer rate between the drives may be reduced to that of the slowest drive.

Do not connect an ATA device as a slave on the same IDE cable as an ATAPI master device. For example, do not connect an ATA hard drive as a slave to an ATAPI CD-ROM drive.

For the cable to function correctly:

•Attach the end of the cable that has a single connector (A) to the server board as shown in Figure 18. The connector at this end of the cable is black and is labeled PRI IDE.

•Attach the end of the cable that has two closely spaced connectors (B) to the drive(s). The connectors at this end of the cable are gray and black and are labeled P2 and P3.

•If connecting only one IDE drive, connect the drive to the gray connector (P3).
