Connecting the SRX550 Services Gateway to the AC Power Source

Caution: Do not mix AC and DC power supplies within the same services gateway because this can damage the device.

A 645 W AC power supply with PoE support ships with the SRX550 Services Gateway. You connect AC power to the services gateway by attaching the power cord from the AC power source to the AC appliance inlet located on the power supply. The power cord is not provided.

To connect the services gateway to an AC power supply:

Caution: You need an electrostatic discharge (ESD) grounding wrist strap while connecting the services gateway to an AC power supply.

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the side of the chassis.
  2. Locate the power cord or cords you will use to connect the services gateway to AC power.
  3. Insert the appliance coupler end of the power cord into the appliance inlet on the power supply.
  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, or as permitted by local code.

  5. Dress the power cord appropriately. Verify that the power cord does not block the air exhaust and access to services gateway components or drape where people could trip on it.

Note: The services gateway must be connected to earth ground during normal operation. The protective earthing terminal on the side of the chassis is provided to connect the services gateway to ground.

Caution: We recommend using a surge protector for the power connection.
