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.
