Preparation
•
Ensure that DEH-234 Entellisys Low Voltage Switchgear Device Replacement Guide is
available for CPU chassis replacement.
•
Ensure that there is a valid option string on a USB, the replacement hardware is ready, the
serial numbers and IP addresses of both CPUs are known. (See
Changing the CPU IP address
