    Install AC Power Supplies

    QFX10008 power supplies are hot-insertable and are field-replaceable units (FRUs). You can install up to six power supplies in a QFX10008. The power supplies install in the rear of the chassis in the slots provided along the left side.

    Caution: Do not mix AC and DC power supplies in the same chassis.

    Before you install an AC power supply in the switch, ensure that you have the following parts and tools available to install an AC power supply in a QFX10008:

    • Electrostatic discharge (ESD) grounding strap
    • Phillips (+) screwdriver, number 1
    • Power cords appropriate for your geographical location.
    • Power cord retainer clips

    To install an AC power supply in a QFX10008 :

    1. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis. There is an ESD point located next to the protective earthing terminal and below PSU 5 on the rear panel .
    2. If the power supply slot 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 19.

    3. Taking care not to touch power supply connections, remove the power supply from its bag.
    4. Peel back and remove the protective plastic wrap that covers all four sides of the power supply.
    5. Ensure the power switch is set to the standby (O) position. This switch turns off the output voltage; it does not interrupt AC.
    6. Unscrew the captive screw in the counterclockwise direction by using the Phillips (+) screwdriver, number 1.
    7. Rotate the captive screw away from the faceplate of the power supply to release the latch.

      Note: You can install the power supplies in any slot labeled PSU 0 through PSU 5 (top to bottom).

    8. Using both hands, place the power supply in the power supply slot on the rear of the system. Slide the power supply straight into the chassis until the power supply is fully seated in the slot. Ensure the power supply faceplate is flush with any adjacent power supply faceplates or power supply cover panels (see Figure 20).
    9. Push the captive screw into the power supply faceplate. Ensure that the screw is seated inside the corresponding hole on the faceplate.
    10. Tighten the captive screw by turning it clockwise by using the Phillips (+) screwdriver, number 1. When the screw is completely tight, the latch locks into the switch chassis.

    11. Locate two power cords shipped with the switch; the cords have plugs appropriate for your geographical location.
    12. Attach each power cord to a dedicated AC power source outlet.
    13. Squeeze the two sides of the power cord retainer clip and insert the ends of the clip into the holes in the bracket on each side of the AC appliance inlets on the AC power supply faceplate. See Figure 21.
    14. Insert the power cord coupler into the power supply.

      Each AC power supply has two independent 16 A rated AC inlets on the faceplate. Each inlet must be connected to a dedicated AC power feed to achieve 2N source redundancy. A single connection can be used if redundancy is not a requirement.

    15. Fasten the cord retainer by lowering the clip over the cord and pushing the cord into the adjustment nut of the cord retainer. Rotate the nut until it is tight against the base of the cord. See Figure 21.

      Warning: Ensure that the power cords do not block access to switch components or drape where people can trip on them.

    16. If the AC power source outlets have a power switch, set them to the on (|) position.
    17. Move the enable switches for input 1 and input 2 to the ON position.
    18. Verify that the INP1 and INP2 LEDs on the power supply faceplate are lit and are on steadily.
    19. Press the power switch to the on (|) position.
