Power consumption for HVAC/HVDC power supplies (maximum configuration)
The maximum power consumption configuration features fans at maximum speed and the FC32-48 blade
installed with optics. Traffic is at full line rate, the smallest packet is 64 bytes, the ambient temperature is
40°C (104°F), and maximum power is used for all supported optics. Power specifications do not include
the power draw for the SX6 extension blade.
Note: Volt-ampere (VA) power measurement is provided only for power consumption using the
maximum configuration.

Power consumption (modules)
For blades in the following table:
v Idle: blade enabled, chips initialized, no optics, ports disabled.
v Typical: blade enabled, optics in 50% of ports, passing line rate.
v Maximum: blade enabled, optics installed, traffic, full–line rate, 64-byte smallest packet, 40°C (104°F)
ambient temperature, maximum power for all supported optics.
Module name Module description Power consumption
CPX6 Control Processor Blade Idle = 38 W
Typical = 45 W
Maximum = 50 W
