2.4.4 External Min SAS 4x Drive Boxes and Drive

Expanders

The Min SAS 4x external cables are used for connection between

the 6Gb/s SAS controller external connectors and connectors on

the external drive boxes or drive expanders (JBOD). The 6Gb/s

SAS controller has Min SAS 4x (SFF-8088) external connector,

each of them can support up to four SAS/SATA signals.

2.5 LED Cables

There is no SGPIO supported in the most of old version SATA back-

plane. The 6Gb/s SAS controller also provides two kinds of alterna-

tive LED cable header to support the fault/activity status for those

backplanes. The global indicator connector is used by the server

global indicator LED.

The following electronics schematic is the 6Gb/s SAS RAID control-

ler logical of fault/activity header. The signal for each pin is cathode

(-) side.

The following diagrams and descriptions describe each type of con-

nector.
