10.4.2

Physical characteristics

This section defines physical interface connector.

10.4.3

Connector requirements

Contact your preferred connector manufacturer for mating part information. Part numbers for SAS connectors

will be provided in a future revision of this publication when production parts are available from major connec-

tor manufacturers.

The SAS device connector is illustrated in Figures 28 and 29.

10.4.4

Electrical description

SAS drives use the device connector for:

•

DC power

•

SAS interface

•

Activity LED

This connector is designed to either plug directly into a backpanel or accept cables.

10.4.5
