Ground the Chassis

To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the chassis to earth ground before you connect it to power.

For installations that require a separate grounding conductor to the chassis, you must attach a protective earthing terminal bracket on the chassis. There are mounting holes for the terminal bracket on the left-rear side of the chassis to connect to the earth ground (see Figure 16).

Before you connect earth ground to the protective earthing terminal of a PTX10016, ensure that a licensed electrician has attached an appropriate grounding lug to the grounding cable.

Caution: Using a grounding cable with an incorrectly attached lug can damage the router.

Ensure that you have the following parts and tools available:

  • An electrostatic discharge (ESD) grounding strap (provided)
  • Protective earthing terminal lug (provided)
  • Grounding cable for your PTX10016 (not provided)—The grounding cable must be 6 AWG (13.3 mm²), minimum 90° C wire, or as permitted by the local code.
  • Grounding lug for your grounding cable (provided)—This bracket attaches to the lower left corner of the PTX10016 router chassis next to PSU 9, providing a protective earthing terminal for the router. The grounding lug required is a Panduit LCD6-10A-L or equivalent.
  • A Phillips screwdriver to tighten the two screws that are mounted on the chassis.

An AC-powered PTX10016 gains additional grounding when you plug the power supply in the router into a grounded AC power outlet by using an AC power cord appropriate for your geographical location.

To connect earth ground to a PTX10016:

  1. Verify that a licensed electrician has attached the cable lug (provided in the accessory kit) to the grounding cable.
  2. Connect the other end of the grounding cable to a proper earth ground, such as the rack in which the router is mounted.
  3. Attach an ESD grounding strap to your bare wrist and connect the strap to the ESD grounding point next to the earthing posts (see Figure 15).

  4. Remove the two screws on the chassis by using a Phillips screwdriver.
  5. Place the chassis grounding lug and cable over the PEM nuts with the cable connection pointing to the left. See Figure 16.

  6. Place the two screws over the grounding lug and grounding cable.
  7. Tighten the two 10-32 screws using a Phillips screwdriver and apply torque between of 30.1 in.-lb (3.4 N-m) and 42.04 in.-lb (4.75 N-m).
  8. Dress the grounding cable and ensure that it does not touch or block access to other device components and that it does not drape where people can trip over it.
