Chapter 3 Installing a Cisco 7500 Series Router
Providing a Ground Connection for the Chassis
Use the following procedure to attach the grounding lug to the chassis grounding receptacles on your
router chassis:
Step 1 Locate the chassis grounding receptacles on your router chassis. For the Cisco 7505, see Figure 1-2; for
the Cisco 7507, see Figure 1-5; for the Cisco 7507-MX, see Figure 1-8; for the Cisco 7513, see
Figure 1-11; for the Cisco 7513-MX, see Figure 1-14; for the Cisco 7576, see Figure 1-17.

Step 2
Use the wire stripping tool to strip one end of the 6-AWG wire approximately 0.75 inches (19.05 mm).
Step 3 Insert the 6-AWG wire into the top of the wire receptacle on the grounding lug. (See Figure 3-1.)
Step 4 Use the crimping tool to carefully crimp the wire receptacle around the wire; this step is required to
ensure a proper mechanical connection.
Step 5 Insert the screws through the holes in the grounding lug and into the chassis grounding receptacles. (See
Figure 3-1.) Ensure that the grounding lug does not interfere with other router hardware, such as
processor modules and the like.
Step 6 Use the Phillips screwdriver to carefully tighten the two screws until the grounding lug is held firmly to
the chassis. Do not overtighten the screws.
Step 7 Prepare the other end of the 6-AWG wire and connect it to the appropriate grounding point at your site
to ensure an adequate chassis ground.
This completes the procedure for providing a chassis ground connection.
