Mainboard Chapter 5 This section provides general information on changing jumper settings as well as specific jumper configuration for individual boards in the system. A single power supply provides the power for all four serverboards. Each serverboard however, can be shut down independently of the other using the power button on its own control panel. An additional power supply module may be added to provide redundant power. The GW170htq F1 includes an InfiniBand port at QDR (quad data rate) speed. InfiniBand is a scalable serial communications link intended for connecting processors with high-speed peripherals. (InfiniBand requires a QSFP connector.)
