Connecting the PTX5000 to AC Power

Tools and Parts Required to Provide AC Power to the PTX5000

If you have an AC-powered router, gather the tools required to connect the PTX5000 to AC power:

  • AC power cords

  • Phillips (+) screwdriver, number 2 to access the metal AC wiring compartment and remove or attach the AC power cord.

  • 1/5-in. (5.5-mm) slotted screwdriver to attach the ground wire and input terminal wires of the AC power cord.

Connecting Power to the PTX5000 Three-Phase Delta AC PDUs

To connect the delta AC power cords to the three-phase delta AC PDUs (see Figure 7):

  1. Switch off the customer-site circuit breakers. Ensure that the voltage across the AC power source is 0 V and that there is no chance that the voltage might become active during installation.
  2. Switch the circuit breaker and power OUTPUT switch on the PDU faceplate to the off (O) position.
  3. Using a number 2 Phillips (+) screwdriver, remove the four screws from the metal retaining bracket located on the lower right of the PDU. Remove the metal retaining bracket from the PDU (see Figure 1).

    Figure 19: Connecting the Metal Retaining Bracket to an AC Power CordConnecting the Metal Retaining Bracket to an AC Power Cord
    Note:

    If you are using 150 A power, you must use a metal bracket that is larger than the default metal bracket. This bracket is shipped along with the High Capacity Delta AC PDUs. Labels on top of the metal brackets specify the power cords that can be used for each bracket (see Figure 20). The installation procedure to connect the metal bracket to the PDU is the same for both metal brackets.

  6. Attach the power cord to the PDU:
    1. Using a number 2 Phillips (+) screwdriver, loosen the two captive screws on the metal AC wiring compartment.
    2. Open the metal door of the metal AC wiring compartment.
    3. Push the wires of the AC power cord into the area for the metal retaining bracket, and pull the wires to the left toward the metal AC wiring compartment.
    4. Using a number 2 Phillips (+) screwdriver, use the four screws on the metal retaining bracket to secure the AC power cord to the PDU (see Figure 21).

  7. Connect the wires to the AC terminal block on the High Capacity Delta AC PDU (Figure 22). Using a 1/5-in. (5.5-mm) slotted screwdriver, loosen each of the input terminal screws and the grounding point screw, insert each wire into the grounding point or input terminal, and tighten the screw.
    1. Insert the wire labeled GND into the grounding point.
    2. Insert the wire labeled L1 into the L1 input terminal.
    3. Insert the wire labeled L2 into the L2 input terminal.
    4. Insert the wire labeled L3 into the L3 input terminal.

  8. Verify that the AC power wiring connections are correct.
  9. Close the door to the metal AC wiring compartment, and use a number 2 Phillips (+) screwdriver to tighten the two captive screws to secure the door to the metal AC wiring compartment.
  10. Verify that the AC power cord does not touch or block access to PTX5000 components, and that it does not drape where people could trip on it.
  11. Before you power on the PDU, select the switch setting corresponding to the AC input power cord that is connected to the PDU. Figure 23 shows an ampere switch, located inside the wiring compartment.

    • If CBL-PTX-AC-D cable is used, set the switch to 60A.

    • If CBL2-PTX-100AC-D cable is used, set the switch to 100A.

    • If CBL2-PTX-150AC-D cable is used, set the switch to 150A.

    You can verify the switch setting by using the show chassis environment pdu command. The command displays the input power rating as shown in the following example:

    show chassis environment pdu 0

    PDU 0 status: State Online BoostConv OK Feed Switch 150Amps <<<=== Hours Used 142 Firmware Version (MCU1) 03.04

    Figure 23: Ampere SwitchAmpere Switch
    Warning:

    If you set the ampere switch in the wiring compartment incorrectly, the AC power cord might overheat. Setting the ampere switch incorrectly might also cause the site circuit breaker to trip.

    Note:

    The system software gets the system power configuration from the PDU and displays it in the output of the show chassis environment pdu command. Depending on the setting, the system software limits the system configuration (FPCs and PICs) to keep the power demand within the maximum output power available from the PDU.

    Note:

    In a redundant system with two PDUs, the PDUs share the load. If the ampere switch setting of one PDU is lower than the other, Junos OS reduces the rating of the other PDU to the lower value.

  12. Repeat the procedure for the other High Capacity Delta AC PDU.
