NOTE: Route all the DC power supply cords away from the fan trays. Make sure that the power
cords do not obstruct the fan trays.
JNP10K-PWR-DC power supplies can use the standard bus or the enhanced bus.
A JNP10K-PWR-DC power supply can operate with only one input DC feed connected. The Routing
Control Board only enables the components for which sufficient power is available.
Each JNP10K-PWR-DC power supply has its own fan and is cooled by its own internal cooling system.
The airflow is from the front of the power supply to the back. Hot air exhausts from the rear of the chassis.
JNP10K-PWR-DC2 Power Supply
The JNP10K-PWR-DC2 power supply provides two power supplies in a single housing that accepts either
60 A or 80 A using four redundant input power feeds. PS_0 and PS_1 each have redundant input feeds:
A0 and/or B0 for PS_0 and A1 and/or B1 for PS_1. The input is configured using a set of dip switches on
the power supply faceplate. The output is dependant on the settings of these dip switches. See
Table 15 on page 66 . This power supply requires the enhanced power bus. See Figure 28 on page 67 .
