DC Power

Supply Fan and

Fan Modules

Three DC power supply/fan modules at the bottom of the CPX shelf provide power and forced-air cooling for the system’s line card cage and transition module card cage (Figure 2–19). A green light indicates when a module is in service and a red light indicates when it is out of service.

Figure 2–19. DC Power Supply/Fan Modules

Three fans provide forced-air cooling for the power supplies, card cage, and transition module card cage (rear of shelf). The fans mount on the front of the shelf in each Power Supply Fan assembly. Only two fans are necessary to provide adequate system cooling. The third fan provides redundancy.

A shutter mechanism is located behind each fan. During normal fan operation, the shutter opens and allows the cooling air to pass freely (Figure 2–20). If a fan fails, the shutters close, preventing the cooling air from escaping through the failed unit.
