Hot-Plug Fans

The ProLiant DL580 Generation 2 server supports redundant hot-plug fans that are
divided into three zones. Each zone is independent of each other and is able to
support N+1 redundancy, as indicated below:
•
PCI-X expansion zone is 1+1 redundant (fans 1 and 2)
•
Memory zone is 1+1 redundant (fans 3 and 4)
•
CPU zone is 2+1 redundant (fans 5, 6, and 7)
This zone configuration enables the server to withstand up to three fan failures,
provided that they are not within the same zone. Within a zone, if the primary fan
fails, the server generates a system alert and commands the redundant fan to function
automatically. The redundant hot-plug fan subsystem protects the various server
components from overheating, provides rapid serviceability, and minimizes the risk
of system interruption.
