U10 Family Product Manual, Rev. A 7 1.5 Seek time Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using drive diagnostics. The specifications in the table below are defined as follows: • Track-to-track seek time is an average of all possible single-track seeks in both directions. • Average seek time is a true statistical random average of at least 5,000 measurements of seeks between random tracks, less overhead.
8 U10 Family Product Manual, Rev. A 1.7.1 Power consumption Power requirements for the drives are listed in the table on page 9. Typical power measurements are based on an average of drives tested, under nominal conditions, using 5.0V input voltage at 25°C ambient temperature. • Spinup power Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed.

14 U10 Family Product Manual, Rev. A 1.10 Electromagnetic susceptibility The drive operates without errors when subjected to the following: Radiated noise ≤ 3 volt/meter, 30 Hz to 500 MHz Electrostatic discharge* ≤ 10 KVolts Magnetic field strength ≤ 5 Gauss * Electrostatic discharge susceptibility is measured with the drive mounted in a representative computer system (mounted to a ground plane with an earth ground). Discharges are applied to the bezel or other external surfaces on the ground plane.
U10 Family Product Manual, Rev. A 15 comply with the directives when used in the test systems, we cannot guarantee that all systems will comply with the directives. The drive is designed for operation inside a properly designed enclosure, with properly shielded I/O cable (if necessary) and terminators on all unused I/O ports. Computer manufacturers and system integrators should confirm EMC compliance and provide CE marking for their products.

U10 Family Product Manual, Rev. A 17 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 unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge (ESD) hazards. Observe the following standard handling and static-discharge precautions: Caution: • The SeaShell™ replaces electrostatic discharge (ESD) bags.
18 U10 Family Product Manual, Rev. A 2.2 Jumper settings 2.2.1 Master/slave configuration The options jumper block shown in Figure 2 is used to configure the drive for operation. It is the 6-pin dual header between the interface connector and the power connector. Use the following settings to configure the drive as a master or a slave. Master or single drive. The drive is configured at the factory for a master or single-drive operation with a jumper set on pins 7 and 8. Drive as slave. Remove all jumpers.
U10 Family Product Manual, Rev. A 19 2.2.2 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. Master and slave drives are determined by their physical position on the cable. To enable cable select, set a jumper on pins 5 and 6 as shown in Figure 2. Refer to your computer manual to determine whether your computer supports this option. 2.2.
