6.1.1Circuit Breaker Type Jumper

Jumper J4G3, shown by letter “B” in Figure 10 , is used to set a threshold for power consumption when operating the server with a single power supply on a lot-line 100/110/115/120/127VAC power circuit. This threshold is required to ensure the power consumption of the server does not exceed the power that can be supplied by a single AC power circuit. When the system has two power supplies installed, a separate AC power circuit is needed for each power supply to guarantee the AC power circuit capability is not exceeded.

When a server is connected to low-line power, the J4G3 jumper sets the following power consumption thresholds:

Pins 1-2 covered: Sets the power consumption threshold to 1350 watts

Pins 2-3 covered: Sets the power consumption threshold to 1100 watts

Power consumption is based on the power consumed within the system. Power factors for inefficiency are not included in the above figures.
