Figure 1-8) The controller module contains no user-serviceable components.
Except when installing/upgrading the cache memory inside, the controller
module should never be removed or opened.
Although the RAID controller can be removed, the only time you should
touch the controller itself is to install the memory modules. The RAID
controller is built of sensitive components and unnecessary tampering can
damage the controller.
If the pre-installed DIMM module is not damaged, it can be reused when
the controller module is being replaced. The controller module, PN: IFT-
83AF24GE16 comes without DIMM module installed.
The heart of the AR3016G RAID controller subsystem is the FC-4G to
SATA-II controller board. The controller comes with two (2) pre-set FC-4G
host channels, CH0 and CH1. The subsystem connects to the external FC-
4G host computer(s) through two (2) FC connectors on the controller
module interface.
The docking connector at the rear of the controller board is used to connect
the controller module to the backplane board. A DDR RAM DIMM socket
is strategically placed in an easily accessible location on the controller board
for easy insertion of the DDR RAM DIMM module.
Cooling module speed detection: When the system temperature breaches
the high temperature threshold, the cooling modules in the subsystem will
automatically switch to high fan speed to cool the subsystem down.
1.2.4 Controller Module Interfaces
All external interfaces that connect to external devices are located on the
controller module rear panel shown in Figure 1-9. The interfaces are listed
below.
