Installation and Maintenance

Always switch off system power before installing or removing the CPU. Confirm the hardware revision, backplane compatibility, configuration, and firmware requirements before replacement.

Keep the module free from conductive dust and excessive moisture. During maintenance, inspect the backplane connector, module housing, and surrounding wiring. Firmware and software compatibility should also be checked when servicing an older CPU350 installation. GE documentation notes specific programming and firmware requirements for later CPU350 revisions.
