Power supply modules

The K2 Summit system has redundant (two) power supplies. You should connect a power cable to each power supply, but both power supplies remain operational if only one cable is connected. The power supplies can be accessed from the rear of the unit. You can remove and replace a power supply while the K2 Summit system is operational. Each power supply has a fan with automatic speed control and status LEDs that indicate current state and health. The power supply has protection for over voltage, over current, and short circuits. The power supply modules plug into the midplane board.
