Installation

For systems using Serial ATA cables, the Serial ATA II specification mandates that host systems connecting to disk drives using SATA cables must ground Pin 11, resulting in disabling staggered spin-up. Typical desktop systems use this configuration.

In backplane (non-cabled) environments or other systems that do not ground Pin 11, DiamondMax 8S 40GB SATA samples pin 11 after power up and before the first FIS is received, detects the floating or high condition of Pin 11, and enables staggered spin-up. In such a system, the host initiates spin-up by sending a COMRESET signal to the drive.

Where Pin 11 has been grounded, but the system builder wants Staggered Spin-up enabled, DiamondMax 8S drives allow use of a jumper to turn on Staggered Spin- up mode. Using a jumper will force a staggered spin-up, overriding whatever state is on Pin 11.

Putting a jumper across the jumper pins (See Figure 4-4) forces the drive to delay spin-up, whether Pin 11 is grounded or not. In older systems where Pin 11 is grounded, this method provides the ability to sequentially spin-up each drive in the system. Table 4-1 shows the different configuration for staggered spin-up when using Pin 11 or jumper.

Note: 1. Pin 11 must not exceed 3.6V.

Note: 2. If a jumper is required, Maxtor recommends a 2 position, low profile shunt with 2 mm pitch and gold finish.

CAUTION: The PCB is very close to the mounting holes. Do not exceed the specified penetration for the mounting screws. The specified screw penetration allows full use of the mounting hole threads, while avoiding damaging or placing unwanted stress on the PCB. Figure 4-5 specifies the mini- mum clearance between the PCB and the screws in the mounting holes.

The Maxtor hard drive design allows greater shock tolerance than that afforded by larger, heavi- er drives. The drive may be mounted in any attitude using four size 6-32 screws with 3 mm maximum penetration and a maximum torque of 5-inch pounds. Allow adequate ventilation to the drive to ensure reliable operation.
