Chapter 5 21
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.
Both the GW170hd F1 and GW170hq F1 models include an InfiniBand port at DDR (dual data rate) and QDR
(quad data rate) speeds, respectively. InfiniBand is a scalable serial communications link intended for
connecting processors with high-speed peripherals. (InfiniBand requires a QSFP connector.)
