Installation
4.3HARDWARE OPTIONS
The configuration of a Maxtor DiamondMax 8S 40GB SATA hard disk drive depends on the host system in which it is to be installed. This section describes the hardware options that you must take into account prior to installation.
4.3.1Jumper Position
The DiamondMax 8S 40GB SATA interface connector shown in Figure 4-4 includes a position for a jumper. See section 4.3.2 Staggered Spin-up, for details on how the jumper is used.
4.3.2Staggered Spin-up
The staggered spin-up feature allows the host to control when a SATA drive initiates spin-up. In a system with many drives, the host may choose not to spin all disk drives at one time, but instead spin up the drives in a sequence. In the latter case, the host “staggers” the time at which each drive spins-up.
DiamondMax 8S 40GB SATA implements the staggered spin-up feature as defined by the SATA II Extensions to Serial ATA 1.0a revision 1.2 specification. After power is applied to the drive, and before the first FIS is received, the drive samples pin 11 on the power connector (See Figure 4-4 ). If the pin is sampled as low or grounded, then Staggered Spin-up is disabled and the drive automatically spins up. If the pin is sampled as floating or high, then Staggered Sign-up is enabled and the drive waits for COMRESET and PHY initialization before spinning up. For more details on SATA PHY initialization, see section 6.8 of the Serial ATA: High speed Serialized AT Attachment Specification, revision 1.0a.
