Blank Modules

007-4498-002
The cooling module consists of fans that pull warm air from a plenum behind the drive
backplane and exhaust the warm air at the rear of the enclosure. The cooling modules
connect to the backplane for power and status signal connections.
The TP900 system requires one cooling module, which is mounted in the rear of the
system. Optionally, a second cooling module can be added to the system to provide
redundant cooling. In this redundant configuration, the cooling modules operate
together; if one module fails, the other module adequately cools the system until the
faulty unit is replaced.
The cooling module has two LEDs that are located on the front panel of the cooling
module. The green LED indicates that the cooling module is functioning properly. The
amber LED indicates a fan failure.
Blank modules are placed in all vacant power supply and cooling module bays to
maintain proper airflow through the system.
