Fan Modules Overview
The switch has three internal hot-swappable fans. A powered switch should always have more than one
operational fan. The switch can operate with two operational fans and one nonfunctional fan, but the failed
fan should be replaced as soon as possible to avoid a service interruption due to a second fan fault.
