QXS Site Planning Guide
Bezel
The QXS 2U drive chassis includes a bezel sub-assembly that attaches to the front panel of the
chassis. The bezel, comprised of a vented cover attached to an electro-magnetic interference (EMI)
shield, is pre-assembled and packed within a box contained in the enclosure master shipping
container.
Instructions for attaching/removing the bezel are provided in the
QXS Bezel Installation Guide
.
CAUTION:
The bezel should be properly installed while the chassis is in operation to ensure
adequate EMI protection for the drives.
