Your equipment rack location must have a local earth ground. This ground can be
either an unpainted spot on the grounded equipment rack frame, or a grounded bus
bar in the equipment room.
Grounding Cable Installation
The ground terminals are located to the left of power supply B on the rear of the Acme
Packet 4600 chassis. The Acme Packet 4600 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 4600.
Note:
Acme Packet 4600 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 4600:
1.
Using an 11/32” nut driver, screw and remove the two kep nuts from the
grounding posts located on the rear of the Acme Packet 4600. Place them aside.
2.
Place the lug on the end of the grounding cable onto the grounding posts.
