In addition, poor equipment placement can make chassis panels inaccessible and difficult to maintain. The switch operates as a standalone system mounted in a rack in a secure wiring closet. It requires a dry, clean, well-ventilated, and air-conditioned environment. To ensure normal operation, maintain ambient airflow. If the airflow is blocked or restricted, or if the intake air is too warm, an overtemperature condition can occur.
Calculating System Heat Dissipation To calculate the expected heat dissipation from a switch, add the total amount of power drawn from power supply by the system's configuration, then divide the total amount of power by the efficiency of the power supply. Multiply the result by 3.415 to get the system heat dissipation in BTUs/hr.
15.4 W at the switch port. 17.3 W comes from the WS-X4248-RJ45V DC-DC converter’s efficiency (89%). Site-Planning Checklist Table 2-2 install a Catalyst 4500 series switch. Completing each activity helps to ensure a successful switch installation. Table 2-2 Site-Planning Checklist Task No.
