Maintaining the PTX5000 AC Power System

Maintaining the PTX5000 AC Power System

Purpose

For optimum performance, verify the condition of the power distribution units (PDUs), power supply modules (PSMs), AC power cords, and grounding cables.

Action

On a regular basis:

  • Periodically inspect the site to ensure that the grounding and AC power cords connected to the PTX5000 are securely in place and that no moisture is accumulating near the PTX5000. To review grounding and site wiring requirements for the PTX5000, see PTX5000 Chassis Grounding Cable and Lug Specifications and Site Electrical Wiring Guidelines.

  • Check the status of the PDUs by issuing the show chassis environment pdu command.

  • Make sure that the AC power cords are arranged so that they do not obstruct access to other router components.

  • Routinely check the status LEDs on the PDU and PSM faceplates and the craft interface to verify that the power system is functioning normally.

    For more information about the PDU and PSM LEDs, see PTX5000 AC Power Distribution Unit LEDs and PTX5000 AC Power Supply Module LEDs.

  • Check the red and yellow alarm LEDs and the LCD display on the craft interface. PDU and PSM failure or removal triggers an alarm that causes one or both of the LEDs to light and an error message to appear on the LCD display. You can display the associated error messages by issuing the following CLI command:

    For a list of possible alarm messages, see Troubleshooting the PTX5000 Power System.

  • The power system requires an unobstructed airflow at both the front and rear of the chassis. Periodically check the site to ensure that both the air intake at the bottom front of the chassis and the exhaust from the PSM faceplates are unobstructed.

  • To check the power usage in watts for all PDUs and PSMs, issue the show chassis power command .

    Issue the show chassis power detail command to check the power usage in watts for hardware components such as FPCs, fan trays, Routing Engine and Control Board, and SIB, CCG, and craft interface.

Replacing a PTX5000 Three-Phase Delta AC PDU

Removing a PTX5000 Three-Phase Delta AC PDU

The PTX5000 has two redundant, load-sharing PDUs. Each PDU is hot-insertable and hot-removable. The PDU weighs 51.2 lb (23.2 kg).

To remove a three-phase delta PDU:

  1. Switch off the customer-site circuit breakers to the PDU being removed.
  2. Switch the circuit breaker and the power OUTPUT switch located on the faceplate of the PDU to the off (O) position.
  3. Disconnect the AC power cord from the power source.
    Note:

    After powering off a PDU, you must wait at least 60 seconds before turning it back on.

  4. Make sure that the voltage across the AC power cord is 0 V and that there is no chance that the AC power cord might become active during the removal process. Verify that the 200-240 V ~ 60 A 50-60 Hz LED on the PDU faceplate is off.
  5. Remove the power supply modules (PSMs) in the front of the chassis from the PDU to be removed (see Figure 1).
    1. Loosen the captive screws on the door covering the PSMs and open the door.
    2. Loosen the captive screw on the PSM ejector handle.
    3. Grasp the ejector handle and pull to eject the PSM.
    4. Slide the PSM halfway out of the chassis. Place one hand underneath the PSM to support it and slide it completely out of the chassis.
    5. Repeat these steps for the remaining PSMs in the PDU.
    Figure 1: Removing the AC Power Supply ModulesRemoving the AC Power Supply Modules
  6. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis at the back of the PTX5000.
  7. Open the door of the metal wiring compartment.
  8. Disconnect the wires from the AC terminal block on the three-phase delta AC power supply (Figure 2). Using a 1/5-in. (5.5-mm) slotted screwdriver, loosen the input terminal or grounding point screw, and remove each wire from the input terminal or grounding point.
    1. Remove the wire labeled L3 from the L3 input terminal.
    2. Remove the wire labeled L2 from the L2 input terminal.
    3. Remove the wire labeled L1 from the L1 input terminal.

    Figure 3: Removing the Metal Retaining Bracket and AC Power CordRemoving the Metal Retaining Bracket and AC Power Cord
  10. Loosen the four captive screws attaching the front PDU handle to the PDU and chassis.
  11. Grasp the front PDU handle on the PDU faceplate and pull firmly down toward you. Slide the PDU halfway out of the chassis until you can reach the installation handle located on top of the PDU. (See Figure 5).
    CAUTION:

    Each PDU weighs approximately 63.3 lb (28.7 kg). Be prepared to support the full weight of the PDU as you remove it from the PTX5000.

  12. Use the installation handle to slide the PDU completely out of the chassis.
  13. Use the captive screws on the metal retaining bracket to reattach it to the PDU being removed.
Warning:

Do not touch the power connectors on the rear of the PDU. They can contain dangerous voltages.

CAUTION:

Do not leave a PDU slot empty for more than a short time while the PTX5000 is operational. For proper airflow, the PDU must remain in the chassis or a blank panel must be used in an empty slot.
