System Overview 17
Refer to the numbers on the CRUs, Figure 17, and the table to identify components within the 2U
chassis. PSU and controller modules are available as CRUs. The RAID chassis use 2-port controller
modules. Use expansion chassis for optionally added storage.
QXS-G2-312 and QXS-G2-324 RAID Chassis (CNC Controllers and 2FC/iSCSI ports)
Figure 17 provides a rear view of the 2U12-drive or 2U24-drive RAID chassis with two CNC controllers
(2 FC/iSCSI ports).

CNC FC/iSCSI Controller
Callout 1, Figure 18, is the Controller A location. Callout 2, Figure 18, is the Controller B location.
Both controllers are shown in the closed/locked position.
Figure 18 provides a rear view of the CNC FC/iSCSI controller used in the 2U12-drive or 2U24-drive
systems. You can configure the CNC host interface ports (Ports 0 and 1) with 8/16Gb/s FC SFPs; 10GbE
iSCSI SFPs; or 1Gb/s RJ-45 SFPs.
