Power consumption of the CP3923:
• Management only (handle open): <1W
• Idle (no links): 11W
• Maximum (full traffic/load): <20W
1.3.4
Temperature
• Operation from -40° C to +70° C (+85°C for 10 min) according EN50155, convection cooled
• RC version: up to 85°C under continuous operation according to VITA 47 (measured at frame-to-housing contact sur-
face)
• Storage temperature range -50° C to +105° C. For the CP3923-RC, the storage temperature is not compliant to VITA
C4, only to VITA C2.
Required average inlet airflow should be around 400LFM (2 m/s) for the maximum cooling of the non-conduction-cooled
versions. Other thermal limitations may apply and are the responsibility of the system integrator. For more information on
temperature, see chapter “Thermal Considerations” on page 67.
