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.
