Replacing the Cooling Fan Module
You are not required to power down the switch to replace the cooling fan module.
The switch can run without fans for a short period of time and can tolerate the
temperatures outlined in the section, “Site Specifications,” in Chapter 2.
Before removing the cooling fan module from the switch, you must remove the fan
module cover and fan access cover, as shown in Figure 6-16.

from the switch. The fan blades may still be turning.
