Installation
Maxtor DiamondMax 8S 40GB SATA 4-9
4.4.2 Ventilation
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).
4.5 COMMBINATION 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
.
4.5.1 DC 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.
4.5.2 External 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.
4.5.3 SATA 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.
