5 Cards
The normal working temperature for cards ranges from -40℃ to 65℃. The overall
power consumption is measured under the following conditions:
u Working voltage: -53.5 V DC
u Room temperature: 25℃ (static power consumption and typical power
consumption) or 55℃ (maximum power consumption)
u Static power consumption: All the broadband ports are deactivated.
u Typical power consumption: 50% of the broadband ports are concurrently
activated.
u Maximum power consumption: 100% of the broadband ports are concurrently
activated.
Note:
u The actual power consumption of these cards may deviate a little
from the values mentioned above due to different power modules
used and component discreteness.
u Generally for access equipment, power consumption is converted
into heat output. The unit of the former is W, and that of the later is
BTU/h. The two units are converted based on the formula 1 W ＝
3.412 BTU/h.
5.3 Core Switch Card
The core switch card aggregates, switches and controls traffic flow, processes
Layer 2 protocols, and manages the faults, performance and configuration of the
equipment.
