NOTE: DC power supplies are shipped only in the redundant configuration of PTX10000 routers.
For details about different chassis configurations, see “PTX10008 Components and Configurations”
on page 35 and PTX10016 Components and Configurations.
Each JNP10K-PWR-DC power supply weighs approximately 6 lb (2.7 kg) and has two independent pairs
of DC input lugs (Input 1, RTN, –48V/–60V and Input 2, RTN, –48V/–60V) on the faceplate of the power
supply. Each inlet requires a dedicated DC power feed. Although each inlet provides sufficient input power
to provide full output, always connect to a dedicated DC power feed to provide redundancy. Only one
power feed is operational at a time.
DC power models employ electronic A-B input selection. It provides 2n source redundancy and n+1 power
supply redundancy using fewer power supplies than you would require in a 2n configuration. Should one
power source fail, electronic A-B input selection routes the power supply to the alternate source.
Each JNP10K-PWR-DC 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 31 on page 67.
