5.2.4
Grounding
The PCBA and HDA grounds are always connected together in the drive and cannot
be disconnected. The drive mounting screws, unless intentionally isolated, will
provide additional ground connections between the HDA and the system chassis. If
the drive isn't grounded via mounting screws as described under “Mounting” on
page 41, there may be increased electrical emissions (EMI).
5.3
Hard Drive Installation
If your system does not support hot plugging (see “Hot Plug Support” on page 20), it
must be turned off and unplugged before installing your hard drive.
5.3.1
Jumper Settings
It is not necessary to place a jumper shunt on the drive for workstation/desktop use.
For enterprise storage enviroments, the advanced settings are as follows:
SSC Mode
– Spread spectrum clocking feature enabled or disabled (jumper on pins 1-
2). Default setting is disabled.
PUIS Enabled Mode
– To designate the drive as power-up in standby (power
management 2 or PM2) enabled, place a jumper on pins 3-4 (default setting is
disabled). This mode enables controlled spinup via spinup command per ATA
standard. It is mainly used for server/workstation environments operating in multiple
drive configurations.
Native Gen2 Enabled Mode
– To revert to the SATA 3 Gb/s data transfer speed, place a
jumper on pins 5-6.
Force Gen1 Enabled Mode
– To revert to the SATA 1.5 Gb/s data transfer speed, place
jumpers on pins 5-6 and 7-8.
Important:
PUIS mode requires a compatible BIOS that supports this feature. If PUIS
is enabled and not supported by BIOS, the drive will not spin up and therefore will
not be detected by the system.
