Configuring and Mounting the Drive
This section contains the specifications and instructions for configuring and mounting the drive.
3.1
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
• Before handling the drive, put on a grounded wrist strap, or ground oneself frequently by touching the metal chassis of a computer
that is plugged into a grounded outlet. Wear a grounded wrist strap throughout the entire installation procedure.
• Handle the drive by its edges or frame
only
.
• The drive is extremely fragile—handle it with care. Do not press down on the drive top cover.
• Always rest the drive on a padded, antistatic surface until mounting it in the computer.
• Do not touch the connector pins or the printed circuit board.
• Do not remove the factory-installed labels from the drive or cover them with additional labels. Removal voids the warranty. Some
factory-installed labels contain information needed to service the drive. Other labels are used to seal out dirt and contamination.
3.2
Configuring the drive
Each drive on the SATA interface connects point-to-point with the SATA host adapter. There is no master/slave relationship because
each drive is considered a master in a point-to-point relationship. If two drives are attached on one SATA host adapter, the host
operating system views the two devices as if they were both “masters” on two separate ports. Both drives behave as if they are Device
0 (master) devices.
SATA drives are designed for easy installation. It is usually not necessary to set any jumpers on the drive for proper operation; however,
if users connect the drive and receive a “drive not detected” error, the SATA-equipped motherboard or host adapter may use a chipset
that does not support SATA speed autonegotiation.
3.3
SATA cables and connectors
The SATA interface cable consists of four conductors in two differential pairs, plus three ground connections. The cable size may be 30
to 26 AWG with a maximum length of one meter (39.37 inches). See
for connector pin definitions. Either end of the SATA
signal cable can be attached to the drive or host.
For direct backplane connection, the drive connectors are inserted directly into the host receptacle. The drive and the host receptacle
incorporate features that enable the direct connection to be hot pluggable and blind mateable.
For installations which require cables, users can connect the drive as illustrated in
Figure 1
Attaching SATA cabling
Each cable is keyed to ensure correct orientation. Enterprise NAS HDD v2 drives support latching SATA connectors.
3.4
Drive mounting
Users can mount the drive in any orientation using four screws in the side-mounting holes or four screws in the bottom-mounting holes.
Refer to
for drive mounting dimensions. Follow these important mounting precautions when mounting the drive:
• Allow a minimum clearance of 0.030 inches (0.76mm) around the entire perimeter of the drive for cooling.
• Use only 6-32 UNC mounting screws.
• The screws should be inserted no more than 0.150 inch (3.81mm) into the bottom or side mounting holes.
• Do not overtighten the mounting screws (maximum torque: 6 inch-lb).
