3.3.1 About Sun Fire X4450 Fans
Six pairs of fan modules are located under the top cover door, providing N+1 cooling
redundancy. Each fan module contains two fans mounted in an integrated,
hot-swappable CRU.
If a fan module fails, replace the fan module as soon as possible to maintain server
availability.
Fan modules are hot-swappable and can be removed and installed while the server is
running without affecting the rest of the server’s capabilities.
