Figure 5-2 Sata 3 Gb/S Jumper Settings - Western Digital caviar blue xl500s Technical Reference Manual

XL500S
5.3.1.2 SATA 3 Gb/s Hard Drives
SSC Mode – Spread spectrum clocking feature enabled or disabled (jumper on pins 1-2).
Default setting is disabled.
PM2 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.
Important: PM2 mode requires a compatible BIOS that supports this feature. If PM2 is
enabled and not supported by BIOS, the drive will not spin up and therefore will not be
detected by the system.
Gen1 Enabled Mode – To revert to the SATA 1.5 Gb/s data transfer speed, place a jumper
on pins 5-6.
