Power Consumption of Standalone Cisco Catalyst 3850 Series Switches
Table 13 shows power consumption of standalone Cisco Catalyst 3850 Series Switches based on Alliance for
Telecommunications Industry Solutions (ATIS) testing using IMIX distribution stream traffic, with input voltage of
115VAC @ 60 Hz and no PoE loading. The values given are the maximum possible power consumption numbers
under the respective test scenarios.
