Connecting an MX10016 to Power

 

Connect an MX10016 to Earth Ground

To ensure proper operation and to meet safety and electromagnetic interference (EMI) requirements, you must connect the chassis to earth ground before you connect power to the device.

You must install the MX10016 in a restricted-access location and ensure that the chassis is always properly grounded. The MFX10016 has a two-hole protective grounding terminal provided on the chassis. See Figure 2. Under all circumstances, use this grounding connection to ground the chassis. For AC-powered systems, you must also use the grounding wire in the AC power cord along with the two-hole grounding lug connection. This tested system meets or exceeds all applicable EMC regulatory requirements with the two-hole protective grounding terminal.

Before you connect earth ground to the protective earthing terminal of an MX10016, ensure that a licensed electrician has attached an appropriate grounding lug to the grounding cable. 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. See Installing an MX10016 into a Four-Post Rack

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 MX10016 (not provided)—The grounding cable must be a 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 MX10016 router chassis next to PSU 9, 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 MX10016 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 MX10016 Power Cord Specifications).

To connect an MX10016 chassis to earth ground:

  1. Verify that a licensed electrician has attached the grounding 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).

  4. Remove the two screws on the chassis grounding point 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 2).

  6. Place the two screws over the grounding lug and grounding cable.
  7. Tighten the two 10-32 screws using a Phillips screwdriver applying 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 could trip over it.

Connecting AC Power to an MX10016

After you ground the chassis, connect the power supplies, and supply power to the chassis, the system initiates the power-on sequence. Although this sequence can start incrementally with a single power supply, we recommend that you power on an MX10016 router with at least three power supplies.

Before you begin connecting power to the router, be sure you understand how to prevent ESD damage (see Prevention of Electrostatic Discharge Damage).

To connect AC power to an MX10016 chassis:

  1. Connect the chassis to earth ground (see Connect an MX10016 to Earth Ground).Caution

    To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, an MX10016 must be adequately grounded before it is connected to power.

    For installations that require a separate grounding conductor attached to the chassis, use the protective earthing terminal on the rear panel of the MX10016 to connect to earth ground.

    An AC- powered MX10016 gets 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 MX10016 Power Cord Specifications.

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

Connecting DC Power to an MX10016

The overall process of powering on a DC-powered chassis involves the proper cabling of the individual power supplies, adding the power supplies to the chassis, and supplying power. Although this sequence can start incrementally with a single power supply, we recommend that you power on an MX10016 router with at least three power supplies.

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

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