Component Power Requirements and Heat Dissipation

Consider heat dissipation when sizing the air-conditioning requirements for an installation. The power

and heat associated with a Cisco MDS 9396T 32-Gbps 96-Port Fibre Channel (FC) Switch varies based upon 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 Cisco MDS 9396T 32-Gbps 96-Port Fibre Channel Switch.

Connection Guidelines for AC-Powered Systems

For connecting the Cisco MDS 9396T switch AC power supplies to the site power source, follow these basic guidelines:

  • Each power supply should have its own dedicated branch circuit.

  • For international, circuits should be sized according to local and national codes.

  • The AC power receptacles used to plug in the chassis must be the grounding type. The grounding conductors that connect to the receptacles should connect to protective earth ground at the service equipment.
