As such, each drive is considered to be a subassembly even when it is individually marketed to the customer. As a subassembly, no Federal Communications Commission authorization, verification or certification of the device is required. has tested this device in enclosures as described above to ensure that the total assembly (enclosure, disc drive, motherboard, power supply, etc. ) does comply with the limits for a Class B computing device, pursuant to Subpart J of Part 15 of the FCC rules. Operation with noncertified assemblies is likely to result in interference with radio and television reception. This equipment generates and uses radio frequency energy and, if not installed and used in strict accordance with the manufacturer's instructions, may cause interference to radio and television reception. This equipment is designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or television, which can be determined by turning the equipment on and off, you are encouraged to try one or more of the following corrective measures: · Reorient the receiving antenna. · Move the device to one side or the other of the radio or TV. · Move the device farther away from the radio or TV. · Plug the computer into a different outlet so that the receiver and computer are on different branch outlets. If necessary you should consult your dealer or an experienced radio/television technician for additional suggestions. You may find helpful the following booklet prepared by the Federal Communications Commission: 14 Marathon 420sl Product Manual, August 1995 How to Identify and Resolve Radio-Television Interference Problems. This booklet is available from the Superintendent of Documents, US Government Printing Office, Washington, DC 20402. Refer to publication number 004-000-00345-4. Marathon 420sl Product Manual, August 1995 15 2. 0 Drive mounting and configuration 2. 1 Handling and static-discharge precautions After unpacking, and before installation, the drive may be exposed to potential handling and ESD hazards. It is mandatory that you observe standard static-discharge precautions. Handle the drive only by the sides of the head/disc assembly. Avoid contact with the printed circuit board, all electronic components and the interface connector. Always rest the drive on a padded antistatic surface until you mount it in the host system. 2. 2 Jumper settings 2. 2. 1 Master/slave configuration You must establish a master/slave relationship between two drives attached to a single AT bus. You can configure a drive to become a master or slave by setting the master/slave jumpers, as described below and shown in Figure 2 on page 16. Alternatively, you can configure the drive as a master or slave using the cable select option. [. . . ] You can use a daisy-chain cable to connect two drives to a single AT host bus. For detailed information regarding the ATA interface, see the ATA-2 Draft Proposed American National Standard, document X3T10/948D (subsequently referred to in this manual as the Draft Proposed ATA-2 Standard). 3. 1 ATA interface signals and connector pins Figure 5 on page 24 summarizes the signals on the ATA interface connector that are supported by the Marathon 420sl. For a detailed description of these signals, refer to the Draft Proposed ATA-2 Standard. 3. 1. 1 AT bus signal levels Signals that the drive sends have the following output characteristics at the drive connector: Logic Low Logic High 0. 0V to 0. 4V 2. 5V to 5. 25V Signals that the drive receives must have the following input characteristics, measured at the drive connector: Logic Low Logic High 0. 0V to 0. 8V 2. 0V to 5. 25V 22 Marathon 420sl Product Manual, August 1995 3. 2 ATA Interface commands 3. 2. 1 Supported ATA commands The following table lists ATA-standard and Seagate-specific drive commands that the Marathon 420sl supports. For a detailed description of these commands, refer to the Draft Proposed ATA-2 Standard. [. . . ]
