212 QXS G2 Hardware Installation and Maintenance Guide
The 5U84 chassis CRU replaces a chassis that has been damaged, or whose midplane has been
damaged. Often, a damaged midplane will appear as though a RAID controller has failed. If you
replace a controller module and it does not remedy the fault, you may need to replace the RAID
chassis.
You can observe chassis health (front panel and rear panel) using management interfaces to verify
chassis/component failure or chassis/component operation. See also
Preparing to Remove a Damaged 5U84 Chassis
Because you are removing and replacing an entire chassis, neither the hot-swap capability that
applies to replacing individual redundant CRUs in an operational chassis, nor the hot-add of a drive
chassis to an operational storage system, apply to this procedure.
