Controller Enclosure Midplane Servicing Notes

AUTION
The controller enclosure’s chassis must be serviced by a trained
service technician ONLY.
To replace the controller enclosure midplane, replace the entire chassis, not just the board.
Servicing the chassis is a major task that requires removing and disassembly. Before
assuming that the midplane is defective, make sure you have thoroughly investigated all
other possibilities, including:
Checking and replacing any defective interface cables, terminators, and host adapters.
Verifying that the controller modules and memory modules are functioning properly.
Verifying that the cooling system is working properly and that the controller modules
are not overheated.
