A switch chassis contains 36 fans modules. Each switch unit has 6 dedicated fan modules. The server will continue to operate at full capacity with 5 of the 6 fan modules operating for each switch unit. If the server is operating with one or more switch units that have only 5 fan modules, and one or more of those fan modules fails, the server will continue operating until defined temperature thresholds are exceeded, at which point the server will perform a graceful shutdown.
For the location of the fan modules in the switch chassis and their respective labels, see Switch Chassis Rear Components (SPARC M7-16).
Caution - This procedure requires that you handle components that are sensitive to electrostatic discharge. This discharge can cause server components to fail. Follow antistatic precautions to prevent electrostatic damage. See Prevent ESD Damage.
These topics explain how to service the fan modules in the switch chassis.
