Installation

4.4.2Ventilation

The Maxtor DiamondMax 8S 40GB SATA hard disk drives operate without a cooling fan, provided the ambient air temperature does not exceed 140° F (60° C).

4.5COMMBINATION CONNECTOR (J1)

The DiamondMax 8S 40GB SATA is equipped with a serial ATA interface connector with integrated power connector, as shown in Figure 4-4.

4.5.1DC Power (J1, Section A)

The recommended mating connectors for the +5 VDC and +12 VDC input power are listed in Table 4-2. Device Plug Connector Pin Definitions.

4.5.2External Drive Activity LED

DiamondMax 8S 40GB SATA supports the activity LED through Pin 11 as defined by the SATA II Extensions to Serial ATA 1.0a r1.2 specification. In systems with SATA cables, the Serial ATA II spec mandates that pin 11 is grounded. However, in a backplane environment or other system where Pin 11 is not grounded, DiamondMax 8S may drive an “activity indicator LED” via pin 11.

After power up and before the first FIS is received, the drive samples pin 11 to detect whether to enable/disable staggered spinup mode (see section 4.3.2). After sampling Pin 11, Pin 11 is driven by the disk drive as needed to turn the LED on. Note that pin 11 behaves like an open collector output, sinking current to activate an LED.

4.5.3SATA Bus Interface Connector

There are two ways you can configure a system to allow the Maxtor DiamondMax 8S 40GB SATA hard disk drives to communicate over the Serial ATA bus of an IBM or IBM-compatible PC:

1.Connect the drive to a Serial ATA bus connector on the motherboard of the PC.

2.Install an SATA adapter board in the PC, and connect the drive to the adapter board.

To prevent the possibility of incorrect installation, the connector is polarized. This ensures that a connector cannot be installed upside down.

See Chapter 6 “Cables and Connectors Specifications” in the “Serial ATA: High Speed Serialized AT Attachment, Revision 1.0a” specification for more information about cable and power requirements.
