Component Power Requirements and Heat Dissipation Specifications

Consider heat dissipation when sizing the air-conditioning requirements for an installation. The power and heat associated with a Cisco MDS 9216 Switch varies based upon the following considerations:

•Switching module type and number of switching modules installed

•Average switching traffic levels

Table B-5lists the power requirements and heat dissipation for the components of the Cisco MDS 9216 Switch.

Note Unless noted otherwise, the data in Table B-5is based on worst-case conditions. Typical numbers are approximately 30 percent below the numbers listed here.
