Connecting the PTX10000 to Power

 

PTX10008 and PTX10016 routers support both AC and DC power supplies. Additionally, PTX10000 routers also support high voltage alternating current (HVAC) and high voltage direct current (HVDC) power supplies..To connect power to a PTX10008 router or a PTX10016 router, refer to the following procedures:

Note

Do not mix power supply models in the same chassis in a running environment. DC and HVDC can coexist in the same chassis during the hot swap of DC for HVDC.

Connecting Earth Ground to a PTX10000

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, you must attach a protective earthing terminal bracket on the chassis. There are mounting holes for the terminal bracket on the left-rear side of the chassis to connect to the earth ground (see Figure 3).

Before you connect earth ground to the protective earthing terminal of a PTX10008 or PTX10016, ensure that a licensed electrician has attached an appropriate grounding lug to the grounding cable.

Caution

Using a grounding cable with an incorrectly attached lug can damage the router.

Note

Mount your router in the rack before attaching the grounding lug to the router. For the PTX10008, see:

Ensure that you have the following parts and tools available:

  • An electrostatic discharge (ESD) grounding strap (provided).

  • Protective earthing terminal lug (provided).

  • Grounding cable for your PTX10000 (not provided)—The grounding cable must be 6 AWG (13.3 mm²), minimum 90° C wire, or as permitted by the local code.

  • Grounding lug for your grounding cable (provided)—This bracket attaches to the lower left corner of the PTX10000 router chassis next to PSU 5, providing a protective earthing terminal for the router. The grounding lug required is a Panduit LCD6-10A-L or equivalent.

  • A Phillips screwdriver to tighten the two screws that are mounted on the chassis.

An AC-powered PTX10000 gains additional grounding when you plug the power supply in the router into a grounded AC power outlet by using an AC power cord appropriate for your geographical location. See PTX10000 Power Cables Specifications.

To connect earth ground to a PTX10008 or PTX10016 chassis:

  1. Verify that a licensed electrician has attached the cable lug (provided in the accessory kit) to the grounding cable.
  2. Connect the other end of the grounding cable to a proper earth ground, such as the rack in which the router is mounted.
  3. Attach an ESD grounding strap to your bare wrist, and connect the strap to the ESD grounding point next to the earthing posts (see Figure 1 and Figure 2).

  4. Remove the two screws on the chassis using a Phillips screwdriver.
  5. Place the chassis grounding lug and cable over the PEM nuts with the cable connection pointing to the left. See Figure 3 and Figure 4.

  6. Place the two screws over the grounding lug and grounding cable.
  7. Tighten the two 10-32 screws using a Phillips screwdriver and apply torque between of 30.1 in.-lb (3.4 N-m) and 42.04 in.-lb (4.75 N-m).
  8. 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 can trip over it.

Connecting AC Power to a PTX10000

The overall process of bringing up the chassis is simple and straightforward. After you ground the chassis, add power supplies, and supply power to the chassis, the system initiates the power-on sequence. This sequence can start incrementally with a single power supply, but it is not recommended that you bring up a PTX10000 system with less than three power supplies.

Before you begin to connect power to the router, be sure you understand how to prevent ESD damage. See Prevention of Electrostatic Discharge Damage.

To connect AC power to a PTX10000 chassis:

  1. Connect the chassis to earth ground (see Connecting Earth Ground to a PTX10000).Caution

    To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, a PTX10000 must be adequately grounded before it is connected to power.

    For installations that require a separate grounding conductor to the chassis, use the protective earthing terminal on the rear panel of the PTX10000 to connect to the earth ground.

    A PTX10000 gets 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 PTX10000 Power Cables Specifications.

  2. Install power supplies in the router and apply power. See Installing a JNP10K-PWR-AC Power Supply.

Connecting DC Power to a PTX10000

The overall process of bringing up a DC-powered chassis involves the proper cabling of the individual power supplies, adding the power supplies to the chassis, and supplying power. The power-on sequence can start incrementally with a single power supply, but it is not recommended that you bring up a PTX10000 system with less than three power supplies.

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

Before you begin to connect power to the router be sure you understand how to prevent electrostatic discharge (ESD) damage. See Prevention of Electrostatic Discharge Damage.
