The card cage can fully accommodate the combination of up to 14 Video Output Modules and data interface modules. The Tiandy Card Cage System employs 110 VAC Switch Mode Power Supply (SMPS) design reducing the possibility of a single point-of-failure that can cause a complete shutdown or a major fault of other modules within the chassis rack. The high stability of the system ensures that if only one module shuts down, the operation of the other modules remains unimpaired. Two air-cooling fans are installed inside to further strengthen the long-reliability of the system and eliminate the necessity of periodic maintenance. Besides, all the modules inserted in the chassis rack are hot-swappable, as a result, it is unnecessary for the users to power-down the rack mount when removing or replacing the modules.
