CAUTION: Before you begin installing 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.
All base configuration PTX10008 routers are shipped with three power supplies; base configuration
PTX10016 routers are shipped with five power supplies. Cover 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 “PTX10008 Components and Configurations” on page 35 and
PTX10016 Components and Configurations.
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.
PTX10000 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
require in a 2n configuration. Should one power source fail, ATS routers the power supply to the alternate
source.
NOTE: For redundancy, always plug the two power cords from each power supply:
•
INP1 into a UPS
•
INP2 into the public electricity supply
Each JNP10K-PWR-AC power supply has a power switch with international markings for on (|) and off
(O), a fan, and four LEDs on the faceplate that indicate the status of the power supply. See
Figure 27 on page 62.
