Connect the PTX10002-60MR to Power

Connnecting power to the PTX10002-60MR involves the following steps and safety precautions to prevent equipment damage and personal injury.

Connect the PTX10002-60MR to Ground

To meet safety and EMI requirements and to ensure proper operation, you must connect the chassis to earth ground before you connect it to power. You must use the protective earthing terminal on the router chassis to connect it to earth ground. 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.

Note:

An AC/HVAC/HVDC-powered PTX10002-60MR gains additional grounding when you plug the power supply unit (PSU) in the device into a grounded power outlet by using a power cord appropriate for your geographical location. SeeTable 4 and Table 5.
CAUTION:

Before you connect the chassis to earth ground, ensure that a licensed electrician has attached the protective earthing terminal lug (provided in the accessory kit) to the grounding cable that you supply. A cable with an incorrectly attached lug can damage the router (for example, by causing a short circuit).
Note:

Mount the router before attaching the grounding lug. See Unpack the PTX10002-60MR.
Note:

You must install the router in a restricted-access location and ensure that the chassis is always properly grounded. The router has a two-hole protective grounding terminal on the rear panel. Under all circumstances, use this grounding connection to ground the chassis. For AC/HVAC/HVDC-powered systems, you must also use the grounding wire in the power cord along with the two-hole protective grounding lug connection. This tested system meets or exceeds all applicable EMC regulatory requirements with the two-hole protective grounding terminal.

Before you connect the router to ground, ensure that you have the following parts and tools available:

  • Grounding lug for your grounding cable—The grounding lug required is a Panduit LCDX4-14AH-L or equivalent—provided.

  • Grounding cable—The grounding cable must be 4 AWG (21 mm²), minimum 75 °C wire, or as permitted by the local code—not provided.

  • Two M6 screws and washers—not provided.

  • A screwdriver appropriate for the screws—not provided.

To connect the router to ground:

  1. Connect one end of the grounding cable to a proper site earth ground, such as the rack in which the router is mounted.
  2. Place the grounding lug attached to the grounding cable over the protective earthing terminal on the chassis.
    Figure 1: Connect a Grounding Cable to the Router Connect a Grounding Cable to the Router
  3. Secure the grounding lug to the protective earthing terminal by using the washers and screws.
  4. 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 could trip over it.

Connect AC, HVAC, or HVDC Power to the PTX10002-60MR

Before you begin connecting AC, HVAC, or HVDC power:

  • Read AC Power Electrical Safety Guidelines and General Safety Guidelines and Warnings.

  • 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.

    Note:

    An AC/HVAC/HVDC-powered router gains additional grounding when you plug the PSU in the device into a grounded power outlet by using a power cord appropriate for your geographical location. See Table 4Table 5.

  • Install the PSU in the chassis.

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

    • An ESD grounding strap—not provided

    • A power cord appropriate for your geographical location (see Table 4Table 5)—provided.

Note:

You must connect each PSU to a dedicated power source outlet.

To connect AC, HVAC, or HVDC power:

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap to a site ESD point.
  2. Ensure that the PSU is fully inserted in the chassis and the latches are secure.
  3. Locate the power cord or cords that are appropriate for your geographical location.
    Warning:

    Ensure that the power cord does not block access to router components or drape where people could trip over it.
  4. Insert the coupler end of the power cord into the power cord inlet on the PSU faceplate.
    Figure 2: Connect a Power Cord to an AC, HVAC, or HVDC PSU Connect a Power Cord to an AC, HVAC, or HVDC PSU
  5. If the power source outlet has a power switch, set it to the off (O) position.
    Note:

    The router powers on as soon as power is provided to the PSU. There is no power switch on the router.
  6. Insert the power cord plug into a power source outlet.
    Note:

    Each power supply must be connected to a dedicated AC power feed and a dedicated customer-site circuit breaker. We recommend that you use a circuit breaker rated with these specifications:

    • AC/HVAC: 277 VAC/20A or as required by local code.

    • HVDC: 500 VDC/20A or as required by local code.
  7. If the power source outlet has a power switch, set it to the on (|) position.
  8. Verify that the status LED on the PSU is lit green.

    If the status LED is lit amber, remove power from the PSU, and replace the PSU. Do not remove the PSU until you have a replacement PSU ready.

Connect DC Power to the Router

Before you begin connecting DC power:

  • Read DC Power Electrical Safety Guidelines and DC Power Electrical Safety Warnings.

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

    CAUTION:

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

  • Install the PSU in the chassis.

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

    • An ESD grounding strap—not provided

    • Power cables—The power cables must be 4 AWG (21 mm²), minimum 75 °C wire, or as permitted by the local code—not provided.

    • Power cable lugs for your power cables—The power cable lugs required is a Panduit LCD4-14AH-L or equivalent—provided.

    • A Phillips (+), number 1 screwdriver—not provided

    • Four hex nuts to secure the power cables to the terminal studs and a wrench to tighten the hex nuts—provided

    • Heat-shrink tubing and a heat gun to shrink the tubing—not provided

Note:

You must connect each PSU to a dedicated power source outlet.

To connect DC power:

  1. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap to a site ESD point.
  2. Ensure that the PSU is fully inserted in the chassis and the latches are secure.
  3. Use the Phillips screwdriver to loosen the screw that secures the cable manager bracket to the PSU terminal block cover.
  4. Remove the cable manager bracket to expose the terminal studs. Keep the bracket aside.
  5. Install heat-shrink tubing insulation around the power cables.

    1. Slide the tubing over the portion of the cable where it is attached to the lug barrel. Ensure that tubing covers the end of the wire and the barrel of the lug attached to it.

    2. Shrink the tubing with a heat gun. Ensure that you heat all sides of the tubing evenly so that it shrinks around the cable tightly.

    Note:

    Do not overheat the tubing.

  6. Connect the DC power cable lugs to the terminal studs on the DC PSU and secure the power cables by using hex nuts.
    Figure 4: Connect DC Power Cables to a DC Power Supply Unit Connect DC Power Cables to a DC Power Supply Unit
    Warning:

    Ensure that the power cables do not block access to device components or drape where people could trip over them.
    CAUTION:

    You must use an appropriate wrench to tighten the hex nuts. Do not overtighten the hex nuts. Applying excessive torque damages the terminal block.
  7. Use a wrench to tighten the hex nuts by applying torque up to 6 lb-in. (0.68 Nm).
  8. Close the input circuit breaker.
    Note:

    We recommend that you equip the facility DC source with a circuit breaker as required by the local code.
    Note:

    The router powers on as soon as power is provided to the PSU. There is no power switch on the router.
  9. Verify that the status LED on the PSU is lit green.

    If the status LED is lit amber, remove power from the PSU, and replace the PSU. Do not remove the PSU until you have a replacement PSU ready.

  10. Align the slots on the cable manager bracket with the slots on the PSU and push it in place. Gently move the bracket to the left to cover the power cables. Secure the bracket to the PSU by tightening the captive screw on the bracket by using the screwdriver.
