Connect the PTX10003 to Power

 

Connecting the PTX10003 to Ground

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, use the protective earthing terminal on the PTX10003 chassis to connect to the earth ground.

Note

An AC-powered PTX10003 gains additional grounding when you plug the power supply into a grounded AC power outlet by using an AC power cord appropriate for your geographical location. See PTX10003 Power System.

Caution

Before you connect power to the PTX10003, a licensed electrician must attach a cable lug to the grounding cables and power cables that you supply. A cable with an incorrectly attached lug can damage the PTX10003 (for example, by causing a short circuit).

Note

Mount the PTX10003 in the rack before attaching the grounding lug to the PTX10003. See Unpacking and Mounting the PTX10003.

Ensure that you have the following parts and tools available (none are provided):

  • Grounding cable—The grounding cable must be 4 AWG (8.4 mm²), minimum 90° C wire, or as permitted by the local code.

  • Grounding lug for your grounding cable—The grounding lug required is a Panduit LCD6-14BH-L or equivalent. For DC installations, the grounding lug is provided.

  • Two #10-32 screws and washers.

  • Screwdriver appropriate for the #10-32 screws.

To connect a grounding cable to the PTX10003:

  1. Attach a grounding cable to earth ground (such as the rack in which the PTX10003 is mounted) and then attach it to the chassis grounding point. Figure 1 and Figure 2 show the location of the chassis grounding point.

    Figure 2: Chassis Grounding Point (PTX10003-80C)

Point (PTX10003-80C)
  2. Secure the grounding lug to the protective earthing terminal with the washers and screws.
  3. 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.

Connecting AC Power to the PTX10003

The power supplies automatically detect whether there is AC or HVDC input voltage and manage the power accordingly. Each 3000 W AC/HVDC power supply module has a single AC or HVDC input and provides 12 V power to the system. The power supply in a PTX10003 is a hot-removable and hot-insertable field-replaceable unit (FRU). After removing the power cord from an individual power supply, you can remove and replace it without powering off the router or disrupting router functions.

Caution

Do not mix AC/HVDC and DC power supplies in the same chassis.

Note

Each power supply must be connected to a dedicated power source outlet.

To connect AC power to a PTX10003:

  1. Wrap and fasten one end of the ESD wrist strap around your bare wrist, and connect the other end of the strap to the ESD point on the device.
  2. Ensure that the power supplies are fully inserted in the chassis and the latches are secure.
  3. Locate the power cords shipped with the PTX10003; the cords have plugs appropriate for your geographical location. See PTX10003 Power System.Warning

    Ensure that the power cord does not block access to router components or drape where people could trip over it.

  4. Connect each power supply to the power sources. Insert the coupler end of the power cord into the AC power cord inlet on the AC power supply faceplate (see Figure 3 and Figure 4).Note

    The coupler end of the power cord model is APP-400.

  5. If the AC power source outlet has a power switch, set it to the off (O) position.Note

    The PTX10003 powers on as soon as power is provided to the power supply. There is no power switch on the router.

  6. Insert the power cord plug into an AC power source outlet.
  7. If the AC power source outlet has a power switch, set it to the on (|) position.
  8. Verify that the status LEDs on each power supply are lit green.

    If the status LED is lit amber, remove power from the power supply, and replace the power supply (see Maintaining the PTX10003 Power Supplies). Do not remove the power supply until you have a replacement power supply ready.

Connecting DC Power to the PTX10003

The DC power supply in a PTX10003 is a hot-removable and hot-insertable field-replaceable unit. You can remove and replace it without powering off the router or disrupting router functions. You do, however, need to remove power from the power supply before attempting to remove the unit.

Warning

A DC-powered PTX10003 is intended for installation only in a restricted-access location.

Before you begin connecting DC power to the PTX10003:

Caution

Do not mix AC and DC power supplies in the same chassis.

Note

Each power supply must be connected to a dedicated power source outlet.

To connect DC power to a PTX10003:

  1. Attach an ESD grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point.
  2. Ensure that the power supplies are fully inserted in the chassis and the latches are secure.
  3. Set the DC input current selector to 80 A.Note

    The PTX10003 does not support an 60 A power source in Junos OS Evolved software release 19.1.

    Figure 5 shows the location of the DC input current selector (sometimes called the “DIP switch”).

  4. Open the cable manager latch on the terminal block cover of a power supply.
  5. Use a Phillips screwdriver to loosen the screw holding the cable manager latch to the power supply terminal block cover. See Figure 6.

  6. Remove the cable manager bracket to expose the four terminal studs.
  7. If you are using straight DC power cables, place the ends of the power cable connectors over the four terminal studs. See Figure 7.

Power Cable to a DC Power Supply in a PTX10003
  8. Connect the power supply to a 80 A power source by securing the power cables to the four terminal studs with hex nuts.
  9. Use a wrench to tighten the hex nuts by applying torque to between 6 lb-in. (0.68 Nm) and 7 lb-in. (0.79 Nm).Note

    The PTX10003 powers on as soon as power is provided to the power supply. There is no power switch on the router.

    Caution

    You must use an appropriate torque-controlled tool to tighten the hexnuts on the DC power cable connector. Do not overtighten the screws. Applying excessive torque damages the terminal block and the wiring tray.

  10. Repeat Step 3 through Step 8 to connect the other DC power supplies.
  11. Verify that the status LEDs on each power supply are lit green and on steadily.

    If the status LED is lit amber, remove power from the power supply, and replace the power supply (see Maintaining the PTX10003 Power Supplies). Do not remove the power supply until you have a replacement power supply ready. The power supplies must be installed in the PTX10003 to ensure proper airflow.

    Caution

    Replace a failed power supply with a new power supply within 30 seconds of removal to prevent chassis overheating.

  12. Reattach the cable manager bracket that you removed in Step6 and tighten the thumb screw. See Figure 8.

  13. Close the cable manager latch to hold the power cables in place. See Figure 9 and Figure 10.

    Warning

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