Component Power Requirements and Heat Dissipation
Consider heat dissipation when sizing the air-conditioning requirements for an installation. The power and
heat associated with this switch varies based on the following considerations:
• The environment (temperature) outside the chassis
• Internal chassis temperature
• Any hardware component failure in the chassis
• Average switching traffic levels
The following table lists the power requirements and heat dissipation for the components of the switch.
