Observe the following standard handling and static-discharge precautions: Caution: · Keep the drive in its static-shielded bag until you are ready to complete the installation. Do not attach any cables to the drive while it is in its static-shielded bag. · Before handling the drive, put on a grounded wrist strap, or ground yourself frequently by touching the metal chassis of a computer that is plugged into a grounded outlet. Wear a grounded wrist strap throughout the entire installation procedure. · Always rest the drive on a padded, antistatic surface until you mount it in the computer. · Do not touch the connector pins or the printed circuit board. · Do not remove the factory-installed labels from the drive or cover them with additional labels. Some factory-installed labels contain information needed to service the drive. Other labels are used to seal out dirt and contamination. 18 Medalist Pro 9140, 6530 and 4520 Product Manual, Rev. B 2. 2 I/O cable and connector The drive uses a 40-pin, male I/O connector with two rows of twenty pins each and a notch for keying. Pin 1 is located near the 4-pin power connector when the I/O connector is mounted. 0. 100 ± 0. 010 0. 70 ± 0. 010 0. 235 ± 0. 025 pin 1 0. 230 ± 0. 003 0. 025 ± 0. 002 0. 025 ± 0. 002 0. 160 1. 90 2. 00 0. 100 typ 0. 070 ± 0. 010 Figure 2.

B 19 2. 4 Options jumper block The options jumper block (J5), shown in Figure 3, is used to configure the drives for operation. It is the 8-pin dual header between the I/O connector and the power connector. Pin 1 is located next to the power connector and is farthest from the printed circuit board. The options jumper block is used to: · Configure the drive for single-drive operation. The jumper settings for these options are shown in Figure 4 on page 20.

[. . . ] If the Synchronous DMA transfer mode was previously chosen by the Set Features, the ATA signal lines change from the old to new definitions as soon as the host allows for a DMA burst. These lines revert back to their original definitions upon the deassertions of ­DMACK at the termination of the DMA burst.
