Multiservice Switch 7400 Hardware Installation, Maintenance, and Upgrade 6.1S2
Grounding a Multiservice Switch 7480
Ground Nortel Networks Multiservice Switch equipment to protect both
personnel and equipment.
Prerequisites
• Ensure that you have read and fully understand the grounding
requirements. For more information, see NN10600-170 Nortel Networks
Multiservice Switch 7400 Hardware Description. If you use a terminal in
your installation, you must ground both the outlet that provides power to
the terminal and the cabinet or rack to the same distribution panel.
Procedure steps
1 Connect one end of the grounding cable to the ground on the shelf
assembly using an 11/32-in. socket wrench. See the figure “Shelf
assembly grounding stud” (page 232).
2 If the device is in a cabinet, connect the other end of the cable to the
grounding nut on the cabinet frame. Use a 3/8-in. socket wrench to do this.
The figure
“Multiservice Switch cabinet grounding points” (page 234)
shows the grounding points in a cabinet.
If the device is in a standard 19-in. rack, connect the other end of the cable
to a ground point on the frame.
Some Multiservice Switch dc-powered devices have an extra lug on the
right-hand side of the terminal block, labeled GND. Do not use this extra
lug. It must remain unconnected.
