About Fan Trays
Four fan trays are located toward the front of the server, arranged in two N+1
redundant pairs. Each fan tray contains a fan mounted in an integrated,
hot-swappable CRU. If a fan tray fails, replace it as soon as possible to maintain
server availability.
Caution – Hazardous moving parts. Unless the power to the server is completely
shut down, the only service permitted in the fan compartment is the replacement of
the fan trays by trained personnel.
