Note:
*JNP10K-PWR-AC2 and JNP10K-PWR-DC2 models can use the standard bus. The available power is 3000 W for
power budget from the power management software.
JNP10K-PWR-AC Power Supply
The AC power supply supports 200–240 VAC. The output is 12 VDC; the output power is 2700 W.
CAUTION: Do not mix AC and DC power supplies in the same chassis. AC and HVAC
can coexist in the same chassis during the hot swap of AC for HVAC. Do not mix AC and
HVAC power supplies in a running environment.
WARNING: The router is pluggable type A equipment installed in a restricted-access
location. It has a separate protective earthing terminal on the chassis that must be
connected to earth ground permanently to ground the chassis adequately and protect
the operator from electrical hazards.
CAUTION: Before you install the router, ensure that a licensed electrician has attached
an appropriate grounding lug to the grounding cable that you supply. Using a grounding
cable with an incorrectly attached lug can damage the router.
The base configuration MX10008 routers are shipped with three power supplies; base configuration
MX10016 routers are shipped with five power supplies. Cover panels are installed over the remaining
power supply slots. You can add additional power supplies to base configuration routers as necessary. For
details about different router configurations, see “MX10008 Components and Configurations” on page 31 .
Each JNP10K-PWR-AC power supply weighs 6.8 lb (3.08 kg) and has 2 independent 16 A rated AC inlets
on the faceplate. Although each inlet provides sufficient input power to provide full output, always connect
to a dedicated AC power feed to provide redundancy. Only one power feed is operational at a time.
MX10000 routers employ automatic transfer switch (ATS) technology. The system provides 2n source
redundancy and n+1 power supply redundancy, allowing you to use fewer power supplies than you would
