Connecting Power to an MX960 Router with High-Voltage Second-Generation Universal (HVAC or HVDC) Power Supplies

To install and power on an MX960 universal (HVAC or HVDC) power supply, use the following procedure.

  1. Verify that the power switch on the power supply is in the off  (O) position.
  2. Ensure that the release lever below the empty power supply slot is locked in the counterclockwise position (see Figure 1).

    If necessary, pull the spring-loaded locking pin in the release lever away from the chassis and turn the release lever counterclockwise until it stops. Let go of the locking pin in the release lever. Ensure that the pin is seated inside the corresponding hole in the chassis.

  3. On the power supply, rotate the metal cover away from the input mode switch to expose the switch.
  4. Using both hands, slide the power supply straight into the chassis until the power supply is fully seated in the chassis slot. The power supply faceplate protrudes beyond the chassis.

    The small tab on the metal housing that is controlled by the release lever must be inside of the corresponding slot at the bottom of the power supply. This tab is used to pull the power supply down in the chassis slot, prior to removing the power supply.

  5. While firmly pushing the handle on the power supply faceplate with one hand, use your other hand to pull the spring-loaded locking pin in the release lever away from the chassis and turn the release lever clockwise until it stops.
  6. Let go of the locking pin in the release lever. Ensure that the pin is seated inside the corresponding hole in the chassis.
  7. Make sure the cover is attached on the power distribution unit on the chassis on the high-voltage second-generation universal (HVAC or HVDC) power supply.
  8. Make sure the grounding cable is attached, see Grounding the MX960 Router.
  9. Locate a power cord with the type of plug appropriate for your geographical location (see High-Voltage Second-Generation Universal (MX960-PSM-HV) Power Cord Specifications for the MX960 Router).
  10. Plug the power cord into the corresponding appliance inlet located in the chassis directly on the power supply.
    Note:

    Each power supply must be connected to a dedicated power feed and a dedicated customer site circuit breaker.

  11. Dress the power cords appropriately. Verify that the power cord does not block the air exhaust and access to router components, and that they do not drape where people could trip on them.
  12. Move the input switch above the power supply to the on (—) position.

  13. If the power supply is correctly installed and functioning normally, the INP OK, DC OK LEDs light steadily, and the PS FAIL LED is not lit.
  14. Repeat steps 1-12 for installing power supplies in slots 1, 2, and 3, where required.
