Connecting the SRX1400 Services Gateway to an AC Power Supply

 

You connect AC power to the services gateway by attaching power cords from the AC power sources to the AC appliance inlets located on the power supplies.

Warning

To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must properly ground the services gateway chassis before connecting power. See Grounding the SRX1400 Services Gateway for instructions.

Caution

Do not mix AC and DC power supplies within the same services gateway. Damage to the services gateway might occur.

To connect the AC power cords to the services gateway for each power supply:

  1. Locate the power cord or cords with the type of plug appropriate for your geographical location to connect the device to AC power.

    For more information about model numbers, see the SRX1400 Services Gateway hardware documentation at www.juniper.net/documentation.

    Note

    The SRX1400 Services Gateways now ship with a retainer clip for the power cord.

  2. If your services gateway is equipped with a wire bail:
    1. Insert the appliance coupler end of the power cord into the appliance inlet on the power supply.

    2. Snap the wire bail on the power supply over the power cord to prevent the power cord from accidentally disengaging.

  3. If your services gateway is equipped with a retainer clip for the power cord:
    1. Squeeze the two sides of the power cord retainer clip and insert the L-shaped ends of the retainer clip into the holes in the bracket on each side of the AC appliance inlet.

    2. Insert the appliance coupler end of the power cord into the appliance inlet on the power supply.

    3. Push the power cord into the slot in the adjustment nut of the power cord retainer clip. Turn the nut until it is snug against the base of the coupler.

  4. Insert the power cord plug into an external AC power source receptacle.Note

    Each power supply must be connected to a dedicated AC power feed and a dedicated external circuit breaker. We recommend that you use a 15 A (250 VAC) minimum circuit breaker, or as permitted by local code.

  5. Dress the power cord appropriately. Verify that the power cord does not block the air exhaust or access to device components and does not cause a tripping hazard.
  6. Repeat Steps 1 through 5 for the second power supply.

If the PWR LED indicates that the power supply is not functioning normally, repeat the installation and cabling procedures.

Note

If power is lost to the services gateway, the Power-On/Power-Off state is retained. For example, if the services gateway loses power while the device is on, when power returns, the device will still be in the On state.
