Configuration Rules

The minimum system configuration requires a complete set of three working fan
■
trays—an I/O fan tray, a CPU fan tray, and a motherboard fan tray.
If the system does not include a secondary CPU fan tray, a CPU fan tray filler
■
panel must be installed in its place.
Caution – All internal options (except disk drives and power supplies) must be
installed only by qualified service personnel.
Caution – A complete set of three working fan trays must be present in the system
at all times. After removing a fan tray, if the system is left with fewer than three
working fan trays, you must install a replacement fan tray immediately to avoid an
automatic thermal shutdown. For more information, refer to the Sun Fire V890 Server
Owner's Guide.
