Installing a MX960 AC Power Supply or High-Voltage Second-Generation Universal (HVAC or HVDC)

 

To install an AC or universal (HVAC/HVDC) power supply (see Figure 1):

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap to an ESD point.
  2. Move the AC input switch in the chassis above the empty power supply slot to the off  (O) position.Note

    When upgrading to enhanced power supplies, always upgrade power supplies in adjacent slots.

  3. 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.

  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 should be flush with any adjacent power supply faceplates.

    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 (see Figure 1). 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. Move the AC input switch in the chassis above 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 AC OK and DC OK LEDs light steadily, and the PS FAIL LED is not lit.

Note

If you are replacing the MX960-PSM-5K-AC or MX960-PSM-HV power supplies on an existing chassis, make sure to replace the agency label on the chassis with the new label. See MX960 Chassis Serial Number and Agency Label.
