Controller Enclosure Midplane Servicing Notes CAUTION 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. 248 Controller Enclosure Troubleshooting
