Connect the PTX10002-60C to Power

Connecting the PTX10002-60C to Ground

You must install the PTX10002 in a restricted-access location and ensure that the chassis is always properly grounded. The PTX10002 has a two-hole protective grounding terminal provided on the chassis. See Figure 1. We recommend that you use this protective grounding terminal as the preferred method for grounding the chassis regardless of the power supply configuration. However, if additional grounding methods are available, you can also use those methods. For example, you can use the grounding wire in the power cord or use the grounding terminal or lug on a DC power supply. This tested system meets or exceeds all applicable EMC regulatory requirements with the two-hole protective grounding terminal

Note:

An AC-powered PTX10002-60C gains additional grounding when you plug the power supply in the device into a grounded AC power outlet by using an AC power cord appropriate for your geographical location. See PTX10002-60C AC Power Cord Specifications.

CAUTION:

Before you connect power to the PTX10002-60C, a licensed electrician must attach a cable lug to the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage the PTX10002-60C (for example, by causing a short circuit).

Note:

Mount the PTX10002-60C in the rack before attaching the grounding lug to the PTX10002-60C. See Mounting the PTX10002-60C in a Rack.

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

  • Grounding cable—The grounding cable must be 8 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.

  • Two #10-32 UNF screws and washers.

  • Screwdriver appropriate for the #10-32 UNF screws.

To connect a grounding cable to the PTX10002-60C:

  1. Connect one end of the grounding cable to a proper site earth ground, such as the rack in which the PTX10002-60C is mounted.
  2. Place the grounding lug attached to the grounding cable over the protective earthing terminal on the chassis (see Figure 1).
    Figure 1: Connecting a Grounding Cable to the PTX10002-60CConnecting a Grounding Cable to the PTX10002-60C
  3. Secure the grounding lug to the protective earthing terminal with 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.

Connecting AC Power to the PTX10002-60C

Ensure that you have a power cord appropriate for your geographical location available to connect AC power to the router.

Before you begin connecting AC power to the PTX10002-60C:

CAUTION:

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

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 router chassis to connect to the earth ground. For instructions, see Connecting the PTX10002-60C to Ground. The router gains additional grounding when you plug the power supply in the router into a grounded AC power outlet by using the AC power cord appropriate for your geographical location. See PTX10002-60C AC Power Cord Specifications.

The power supply in a PTX10002-60C 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 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 PTX10002-60C:

  1. To prevent damage to the equipment caused by static discharge, attach an electrostatic discharge (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. Locate the power cords shipped with the PTX10002-60C; the cords have plugs appropriate for your geographical location. Refer to PTX10002-60C AC Power Cord Specifications
    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 2).
    Figure 2: Connecting an AC Power Cord to an AC Power Supply in the PTX10002-60CConnecting an AC Power Cord to an AC Power Supply in the PTX10002-60C
  5. If the AC power source outlet has a power switch, set it to the off (O) position.
    Note:

    The PTX10002-60C powers on as soon as power is provided to the power supply. There is no power router 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. Repeat Step 4 through Step 6 for each power supply that you are connecting to power.
  9. 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 Removing a Power Supply from the PTX10002-60C). Do not remove the power supply until you have a replacement power supply ready. The power supplies or a blank cover panel must be installed in the router to ensure proper airflow.

    CAUTION:

    Replace a failed power supply with a blank panel or new power supply within 1 minute of removal to prevent chassis overheating.
