Common Tasks
Replacing the CEM3 Processor
When you remove a CEM3 processor from a rack the CEM3 configuration is stored in the backplane.
If you replace the processor with a different CEM3 processor you will be prompted to select the desired
configuration.
Configuration Selection
When a CEM3 processor that contains an existing configuration is moved to a different rack, the CEM3
will detect that it has been moved and prompt you to select the rack configuration to use. A timer
counts down from 15 seconds before defaulting to [Use the Rack Config]. Within 15 seconds you can
choose to [Abort] the operation.
• If the rack type is suited to work with the backplane configuration or the CEM3 configuration,
you can choose to use either configuration.
• If the rack type is not suited to work with the backplane configuration, you will be given an option
to select the backplane configuration or to clear the configuration and generate a new
configuration.
Incorrect Version
When switching CEM3 processors, the software version of the backplane may not match the software
version of the CEM3. This results in a backplane version mismatch. You can either [Generate New
Config] or [Use CEM3 Config].
When switching CEM3 processors, the rack type configuration may not match the configuration set on
the backplane switches. If this occurs the CEM3 processor will display a rack mismatch. Select
[Generate New Config] to generate a new default configuration.
Recording and Playing Presets
CEM3 has the ability to record and play back snapshot looks called “Presets.”
Presets can be recalled from the CEM3 or from any compatible Echo preset stations or the web
interface. For information on wiring preset stations, see the
Sensor3 CEM3 Data Terminations Guide
and the
Echo preset Station Installation Guide.
Up to 64 presets can be recorded for each space, numbered from 1–64. Only one preset can be active
at a time in the same space.
