Providing a Chassis Ground Connection for the Router Chassis
Providing a Chassis Ground Connection for the Router Chassis
Before you connect power or turn on power to your router, we strongly recommend that you provide an
adequate chassis ground (earth) connection for your router’s chassis. Chassis grounding receptacles are
provided on each Cisco 7206 router chassis. (Refer to Figure 3-11.)
Note Older Cisco 7206 router chassis do not have the grounding receptacles. If you have a Cisco 7206 chassis
that does not have the grounding receptacles and you want to make appropriate ground connections to
your router, you must order a Cisco 7206 router chassis that has the grounding receptacles.
To ensure the chassis grounding connection that you provide is adequate, you will need the following
parts and tools:
• One grounding lug—Must have two number-10 screw holes that have a 0.63-inch (16.002-mm)
spacing between them, and a wire receptacle large enough to accept a 6-AWG multistrand, copper
wire. (See Figure 3-12.) This grounding lug is not available from Cisco Systems;
electrical-connector vendors provide this type of grounding lug.
• Two Phillips-head machine screws with locking washers—M5 (metric), 0.031-inch (0.8-mm) pitch,
0.315-inch (8-mm) length. These screws are not available from Cisco Systems; they are available
from any commercial hardware vendor.
• One grounding wire—6-AWG, 0.162-inch (4.115-mm) diameter, with approximately 0.108-inch
(2.743-mm) insulation, for a total wire diameter of approximately 0.27 inches (6.858 mm). The wire
length is dependent on your router location and site environment. This wire is not available from
Cisco Systems; it is available from any commercial cable vendor.
• Number 2 Phillips screwdriver
• Crimping tool large enough to accommodate the diameter of the wire receptacle on your grounding
lug
• Wire stripper
