Galaxy Raid GHDX4 SAS<>SAS / SATA 12Bay Installation / Hardware Reference Manual
Although the RAID controller can be removed, the only time you
should touch the controller itself is to install or replace the memory
module and CBM. The RAID controller is built of sensitive
components and unnecessary tampering can damage the
controller.
The docking connector at the rear of the controller board connects the
controller module to the backplane board.
1.2.3 Controller Module Interfaces
The controller interfaces are accessed through the controller
faceplate as shown in the figure below.
˙
Mini SAS6G Host Ports: The RAID controller features two (2)
6Gb/s SAS host ports labeled CH0 and CH1.
˙
SAS Expansion: The SAS Expansion port is meant to connect
to JBOD expansion enclosures. The subsystem can connect to a
maximum of six (6) expansion enclosures. For the expansion
connection, you need SFF-8088 to SFF-8088 SAS cables. All
Galaxy JBOD expansion enclosures ship with SFF-8088 to SFF-
8088 SAS cables.
˙
Serial Port: The controller module comes with one (1) COM port.
The serial port is used for local access to the firmware-
embedded, menu-driven configuration utility using a terminal
emulation program.
˙
Ejection Levers: Two (2) ejection levers on the sides of the
controller ensure that the back-end connectors are properly
seated in the module slot and properly mated with the backplane.
