Medalist Pro 2520/2160 Product Manual, Rev. C 2.0 Configuring and mounting the drive This section contains the specifications and instructions for configuring and mounting the drive. 2.1 Handling and static-discharge precautions After you unpack the drive, and before you install it in a system, be careful not to damage it through mishandling.
Medalist Pro 2520/2160 Product Manual, Rev. C 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 20 is removed for keying purposes. A drawing of the I/O connector is shown in Figure 2.
Medalist Pro 2520/2160 Product Manual, Rev. C 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.

Configuration Settings 2.4.1 Master/slave configuration Use the following settings to configure the drive as master or slave.
You can connect a remote LED to pins 1(–) and 2(+) of the options jumper block (J5). Do not install a shunt jumper on these pins. Because the jumper block uses a 0.1-inch connector, you may need to replace the current connector. Use Seagate connector part number 10562-001 or an equivalent. 2.4.4 Cable-select option Computers that use cable-select determine the master and slave drives by selecting or deselecting pin 28, CSEL, on the interface bus.

Medalist Pro 2520/2160 Product Manual, Rev. C 3.2.2.1 PIO and DMA Data-Transfer Modes You can set the multiword DMA mode and identify the PIO data-transfer mechanism and transfer mode with the Set Features command. To set the multiword DMA mode: 1.
Idle command or Standby command. The value corresponds to a predetermined period of drive inactivity. The table below lists the values the Seagate drives use and their corresponding timeout period.
Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) is an emerging technology that provides near-term failure prediction for disc drives. When S.M.A.R.T. is enabled, the Seagate drive monitors prede- termined attributes within itself that are susceptible to degradation over time. S.M.A.R.T. makes a status report available so that the host can prompt the user to back up the drive if self-monitoring determines that a failure is likely.
