When installing Quareo Network Chassis in the odd spaces (1, 3, 5, 7) the first chassis in each
space is secured using the top mounting hole in the chassis and the lowest hole in chassis. When
installing Quareo Network Chassis in the even spaces (2, 4, 6, 8) the first chassis in each space is
secured using the second mounting hole in the chassis and the lowest hole in chassis. See
Figure 3

Grounding Chassis
This procedure establishes a ground connection between the chassis and the earth ground
connection. Frame ground terminations (10-32 screws) are provided on the chassis, for a frame
ground connection. This connection must be made in accordance with all local and national
electrical codes.
1. Locate ground location on chassis, see
Figure 4
. At grounding location remove protective
tape from chassis.
2. Using AWG 14 (1.6mm) solid copper wire, secure two hole ground lug to one end of the
ground wire (installer provided). Secure ground lug to chassis with two 10-32 screws.
Torque ground screws to approximately 15 pound-inches (1.7 Newton meters).
3. To assure proper operation the chassis should be connected to a good earth ground. There
must be no switching or disconnecting devices in the grounding circuit conductor between
the power source and the point of connection to the grounding electrode conductor.
Caution: Reliable earthing of rack-mounted equipment should be maintained. Particular attention
should be given to supply connections other than direct connections to the branch circuit (e.g. use
of power strips).
