34 QXS 12G Site Planning Guide
The 5U84 chassis can be configured as a RAID chassis or an expansion chassis.
Tab l e 15 provides the QXS-484 12G chassis components/CRUs.
CAUTION: The RAID chassis supports 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.

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.
