The Tiandy TC-4020 series Card Cage System can accommodate the combination of up to 12 two/four channels of video output modules and data interface modules. The Tiandy card cage employs 110/220 VAC Switch Mode Power Supply (SMPS) design, which reduces the possibility of a single module failure causing a shutdown or a major failure of other modules with the chassis rack. The high reliability and stability ensures that if one module shuts down, the operation of the other modules remains unimpaired.

Two air-cooling fans are installed inside to further strengthen the superior performance of the system and eliminate the necessity of periodic maintenance. Status information can be read through the LED indicator on each module card. All the modules inserted in the chassis rack are hot-swappable, which makes it unnecessary for the user to power-down the rack mount when replacing the modules.
