MX960 Ethernet Services Router DC Power Supply Installation Instructions

■Attach the positive (+) DC source power cable lug to the RTN (return) terminal.

■Attach the negative (–) DC source power cable lug to the –48V(input) terminal.

NOTE: The DC power supplies in slots PEM0 and PEM1 must be powered by dedicated power feeds derived from feed A, and the DC power supplies in slots PEM2 and PEM3 must be powered by dedicated power feeds derived from feed B. This configuration provides the commonly deployed A/B feed redundancy for the system. For information about connecting to DC power sources, see the MX960 Ethernet Services Router Hardware Guide.

11.Secure each power cable lug to the terminal studs, first with the split washer, then with the nut. Apply between 23 lb-in. (2.6 Nm) and 25 lb-in. (2.8 Nm) of torque to each nut.

12.Loosen the captive screw on the cable restraint on the lower edge of the power supply faceplate.

13.Route the positive and negative DC power cables through the left and right sides of the cable restraint.

14.Tighten the cable restraint captive screw to hold the power cables in place.

15.Replace the clear plastic cover over the terminal studs on the faceplate.

16.Verify that the ground and power cabling are correct, that they are not touching or blocking access to router components, and that they do not drape where people could trip on them.

17.Switch the circuit breaker on the power supply to the ON position and observe the status LEDs on the power supply faceplate. If the power supply is correctly installed and functioning normally, the PWR OK, BREAKER ON, and INPUT OK LEDs light steadily.
