Drive Specifications www.seagate.com 2.6.1 Conducted noise Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on the +12V line or an equivalent 15-ohm resistive load on the +5V line. • Using 12-V power, the drive is expected to operate with a maximum of 120 mV peak-to-peak square-wave injected noise at up to 10MHz. • Using 5-V power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave injected noise at up to 10MHz.
www.seagate.com 2.7 Drive Specifications Environmental specifications 2.7.1 Ambient temperature Ambient temperature is defined as the temperature of the environment immediately surrounding the drive. Actual drive case temperature should not exceed 69°C (156°F) within the operating ambient conditions. Operating 0° to 60°C (32° to 140°F) Nonoperating * –40° to 70°C (–40° to 158°F) * See Section for reliability projections. 2.7.
Drive Specifications www.seagate.com 2.7.5 Shock All shock specifications assume that the drive is mounted securely with the input shock applied at the drive mounting screws. Shock may be applied in the X, Y or Z axis. 2.7.5.1 Operating shock These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 63 Gs based on half-sine shock pulses of 2ms during read operations. Shocks should not be repeated more than two times per second. 2.7.5.
www.seagate.com Drive Specifications 2.8.1 Test for Prominent Discrete Tones (PDTs) Seagate follows the ECMA-74 standards for measurement and identification of PDTs. An exception to this process is the use of the absolute threshold of hearing. Seagate uses this threshold curve (originated in ISO 3897) to discern tone audibility and to compensate for the inaudible components of sound prior to computation of tone ratios according to Annex D of the ECMA-74 standards. 2.
Drive Specifications www.seagate.com 2.10 Warranty To determine the warranty for a specific drive, use a web browser to access the following web page: support.seagate.com/customer/warranty_validation.jsp From this page, click on the “Verify Your Warranty” link. You will be asked to provide the drive serial number, model number (or part number) and country of purchase. The system will display the warranty information for your drive. 2.11 Agency certification 2.11.
www.seagate.com Drive Specifications 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.
Drive Specifications www.seagate.com caution exposing any electronic components to uncontrolled chemical pollutants and corrosive chemicals as electronic drive component reliability can be affected by the installation environment. The silver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur is found to be the most damaging.
3.0 Configuring and Mounting the Drive This section contains the specifications and instructions for configuring and mounting the drive. 3.1 Handling and static-discharge precautions After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge (ESD) hazards.
Configuring and Mounting the Drive www.seagate.com For installations which require cables, you can connect the drive as illustrated in Figure 5. Figure 5 Attaching SATA cabling Signal connector Power connector Signal cable Power cable Each cable is keyed to ensure correct orientation. Barracuda drives support latching SATA connectors. 3.4 Drive mounting You can mount the drive in any orientation using four screws in the side-mounting holes or four screws in the bottom-mounting holes.
