Patent ID: 8736117

Claim:
A server rack system comprising: a rack having a plurality of pairs of guiding rails, a front end, and a rear end opposite to the front end; a power transmission module comprising: at least one first conductive pillar configured at the rear end and electrically connected to an external power supply; at least one second conductive pillar configured at the rear end; and a third conductive pillar configured at the rear end; a power supply module adapted for sliding into the rack from the front end and being slidably configured on one of the pairs of the guiding rails, when the power supply module is completely installed in the rack, the power supply module being electrically connected to the at least one first conductive pillar, the at least one second conductive pillar, and the third conductive pillar and receiving high-voltage direct-current electric power from the external power supply through the at least one first conductive pillar; and a plurality of operating units adapted for sliding into the rack from the front end and being slidably configured on the guiding rails, when the operating units are completely installed in the rack, the operating units being electrically connected to the at least one second conductive pillar and the third conductive pillar respectively, wherein when one of the operating units is completely installed in the rack, the completely installed operating unit transmits a signal indicating the complete installation to the power supply module through the third conductive pillar, and the power supply module converts the high-voltage direct-current electric power into low-voltage direct-current electric power based on the signal indicating the complete installation and transmits the low-voltage direct-current electric power to the operating units through the at least one second conductive pillar.
