SATA Interface (J10, J15)
The VL-EPICs-36 provides two serial ATA (SATA) ports, which communicate at a rate of up to
3.0 GB/s (SATA 2). The SATA connectors at locations J10 and J15 are standard 7-pin straight
SATA connectors with friction latching. Power to SATA drives is supplied by the ATX power
supply. Note that the standard SATA drive power connector is different than the common 4-pin
Molex connector used on IDE drives. Most current ATX power supplies provide SATA
connectors, and many SATA drives provide both types of power connectors. If the power supply
you are using does not provide SATA connectors, adapters are available.
