3.3.1 About Sun Fire X4140 Server Fans
Seven 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 as soon as possible to maintain server
availability.
