QXS-312/412 12G System Specifications 13
2U12-Drive RAID and Expansion Chassis Weight
Table 7 identifies the weight of the QXS-312/412 12G, 2U12-drive RAID and expansion chassis.
Bezel
The 2U12 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 12G Hardware Installation and
Maintenance Guide
.
CAUTION: The bezel should be properly installed while the chassis is in operation to ensure
adequate EMI protection for the drives.
