Blower modules
The blower modules are hot-swap units that are installed into the rear of the
system. The BladeCenter T unit comes with four blowers that are in a 3+1
redundancy configuration. All the cooling requirements are met if one blower fails.
All blowers contain a backflow device that prevents the system from drawing air into
the exhaust port of a failed blower. The management module in the BladeCenter T
unit controls the blower speed and detects blower failures.
