Quantum QXS G2 Series User Manual

System Overview 15
IMPORTANT: The RAID chassis support dual-controller configuration only. If a partner controller
fails, the storage system will fail over and run on a single controller module until the redundancy is
restored. A RAID controller or expansion IOM must be installed in IOM slot to ensure sufficient air
flow through the chassis during operation.
2U Chassis Core Product
The design concept is based on a chassis subsystem together with a set of plug-in modules. A typical
chassis—as supplied—includes the following:
• A chassis which includes the midplane PCB and an integral operator’s (Ops) panel that is mounted
on the left ear flange at the front of the chassis.
• A bezel shipped in a separate box and must be installed on site.

PSUs
1
: Redundant PSUs must be compatible modules of the same type (both AC). Power cords are shipped
with all chassis.
IOMs
2
: Supported expansion IOMs are used in expansion chassis for adding storage.
Fan Modules
3
: The fan modules are separate CRUs and not integrated within the PSUs. Fan modules are
only used within the 5U84 drive chassis.
Bezel
4
: Bezels ship as follows:
• The 2U12 chassis has a bezel shipped in a separate box and must be installed on site.
• The 2U24 chassis has a bezel shipped in a separate box and must be installed on site.
• The 5U84 chassis ships with the bezels (2 each) installed on the upper drawer (Drawer 0) and the lower
drawer (Drawer 1).
Note: Ethernet cables are shipped with all RAID chassis.
