Grounding Cable Installation

The ground terminals are located on the right side of the rear chassis. The Acme Packet 6400 ships with 2 kep nuts screwed onto the ground terminals. Use an 11/32” nut driver to remove and install these kep nuts.

This section shows you how to install the grounding cable on your Acme Packet 6400.

Important: Acme Packet 6400 equipment is suitable for installation as part of a Common Bonding Network (CBN).

Note:

The CBN is a term used for the connection of building steel, water pipes, cable racks, vertical and horizontal equalizer conductors, bonding conductors and electrical metallic raceways within a building, when they are bonded together by either deliberate or incidental connections. The CBN is also connected to the building’s grounding electrode system. Connections to the CBN are usually made from equipment frames to reduce voltage differences to acceptable levels when current flows through these frames, either during fault occurrences in the AC or DC power systems, or when lightning strikes.
  1. Using the 11/32 nut driver, loosen and remove the two kep nuts from the grounding posts located on the rear of the Acme Packet 6400. Place them aside.

  2. Place the lug on the end of the grounding cable onto the grounding posts.
  3. Screw the two kep nuts onto the grounding post and secure the grounding lug in place using the 11/32 nut driver. When attached correctly, the grounding lug fits snugly between the chassis’s rear panel and the kep nuts. Connect the other end of the grounding wire to a suitable grounding point at your site.

    Note:

    Always make the ground connection first and disconnect it last when installing or removing the system from an equipment rack.
