Chapter1 Product Overview

Rear Panel

For information about replacing a power supply module, wiring a DC power supply module, and module

specifications, see Chapter3 , “Power Supply Installation,” and AppendixA, “Technical Specifications.”

Fan Modules

The switch has three internal hot-swappable 12-V fan modules. The air circulation system consists of

the fan modules and the power supply modules. The airflow patterns vary depending on the power supply

configuration.

Figure 1-8 shows the airflow patterns for the 24- and 48-port switches. The blue arrow shows cool air

flow, and the red arrow shows warm air flow. When the fan modules are operating properly, a green LED

is on at the top left corner of the fan assembly (viewed from the rear). If the fan fails, the LED turns to

amber. The switch can operate with two operational fans, but the failed fan should be replaced as soon

as possible to avoid a service interruption due to a second fan fault.

Note Three fans are required for proper cooling.
