Falcon 24 Bay SCSI-SATA Installation and Hardware Reference Manual
1.2.3 RAID Controller Module
Part Number: IFT-84AU24GD24C
The RAID controller module contains a main circuit board and a daughter card providing
management interface connectors, a dedicated drive-plane management interface, and a
preinstalled 256MB DDR RAM DIMM. Use of a BBU module is optional. If BBU
protection is preferred, the BBU is installed in the module bay located at the top center of
the controller module. The BBU can be independently inserted or removed. Please note:
The controller module contains no user-serviceable components. Except when replacing
a faulty unit or installing/upgrading the cache memory inside, the controller module
should never be removed from the subsystem.
WARNING!
Although the RAID controller can be removed, the only time you should touch the
controller itself is to install or replace memory modules. Unnecessary tampering with
the RAID controller can damage the controller and make the system unusable.
Figure 1-8: RAID Controller Module Faceplate
The controller module faceplate is shown in Figure 1-8 and has four (4) VHDCI ports
(labeled CH0-Out, CH0-In, CH1-Out, and CH1-In); two (2) RS-232C (audio jack)
serial ports (labeled COM1 and COM2); one (1) RJ-45 Ethernet connector and four (4)
status-indicating LEDs (labeled from 1 to 4). The controller board is contained within a
metal canister and can only be seen after the controller module has been removed from
the subsystem enclosure. The controller canister has two (2) ejector levers that secure the
controller module to the subsystem chassis. These levers are, in turn, secured to the
enclosure chassis with two (2) retention screws.
