Figure 119: Connecting the DC Power Supply Cables to an JNP10K-PWR-DC
Each power supply has two independent sets of DC power input terminals (INPUT 1: RTN –48V/–60V:
and INPUT 2: : RTN –48V/–60V). For feed redundancy, each power supply must be powered by
dedicated power feeds derived from feed INPUT 1 and feed INPUT 2. This configuration provides the
commonly deployed INPUT 1 / INPUT 2 feed redundancy for the router. There is basic insulation
between the inputs and the chassis ground. Also, there is basic insulation between RTN input feeds.
11. Install the plastic cable cover over each set of power cables by using the Phillips (+) screwdriver,
number 2, to tighten the screw.
12. If the power supply slot on the chassis has a cover panel on it, insert your thumb and forefinger into
the finger holes, squeeze, and pull the cover out of the slot. Save the cover panel for later use (see
Figure 120 on page 226 for MX10008 installations and Figure 121 on page 226 for MX10016 installations).
