Chapter 3 Installing a Cisco 7100 VPN Series Router
Attaching a System Ground Connection
Installing the Chassis in a Rack
After the brackets are secured to the chassis, you can rack-mount the router. Using the screws that you
provide, attach the chassis to the rack as shown in Figure 3-5. You need two people to install the chassis
in the rack—one person to hold the router and one person to secure it to the rack.
If you rack-mount the router with the back panel forward, you might need to attach the system ground
connection before you rack-mount the router. For instructions on how to connect the system ground, see
the next section, “Attaching a System Ground Connection.”

Attaching a System Ground Connection
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 router chassis.
You will need the following parts and tools:
• One grounding lug—Must have two M3.5 screw holes that have a 0.63-inch (16.002-mm) spacing
between them, and a wire receptacle large enough to accept a 6-American Wire Gauge (AWG)
multistrand, copper wire. This grounding lug is provided in the accessory kit.
• Two slotted hexhead M3.5 x 7-mm thread-forming machine screws. These screws are provided in
the accessory kit.
• One grounding wire—6-AWG, 0.162-inch (4.115-mm) diameter, with approximately 0.108 inch
(2.743 mm) of insulation, for a total wire diameter of approximately 0.27 inch (6.858 mm). The
wire’s 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.
• Flat-blade screwdriver.
• Crimping tool large enough to accommodate the diameter of the wire receptacle on your grounding
lug.
• Wire stripper.
