Connect DC Power to an ACX710 Router


Before you begin connecting DC power to the router:

  • Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage).

  • Ensure that you have connected the router chassis to earth ground.


    Before you connect power to the router, a licensed electrician must attach a cable lug to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the router (for example, by causing a short circuit).

    To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the chassis to earth ground before you connect the chassis to power. For installations that require a separate grounding conductor to the chassis, use the protective earthing terminal on the router chassis to connect to the earth ground.

  • Ensure that you have the following parts and tools available:

    • DC power source cables

    • Phillips (+) screwdriver, number 2 (not provided)

    • Multimeter (not provided)

To connect DC power to an ACX710 router:

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap to the site ESD point.
  2. Power off the DC input appliance inlet on the source power supply.
  3. Connect the power cord to the power source outlet.
  4. Insert the power cord firmly into the inlet.

  5. Route the power cord appropriately. Verify that the power cord does not block the air exhaust or access to router components, or drape where people could trip over it.
  6. Power on the source power supply.
