Fan Module Overview

Depending on the switch model, three or five internal hot-swappable are available. 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.
