Grounding Cable Installation

The ground terminals are located to the left of the two power supplies, in the rear of the chassis. The Acme Packet 6300/6350 ships with 2 kep nuts screwed onto the ground terminals. You 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 6300/6350.

Important: Acme Packet 6300/6350 equipment is suitable for installation as part of a Common Bonding Network (CBN).

Note:

The Common Bonding Network (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.

To install the grounding cable on the Acme Packet 6300/6350:

1. Unscrew and remove the two kep nuts from the grounding posts located on the rear of the Acme Packet 6300/6350. Place them aside.

3. Screw the two kep nuts onto the grounding post, securing the grounding lug in place. 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.
