Use two screws for each side (supplied with the rack, not with the router). Tip Start the lower pair of screws first, and rest the brackets on the lower screws while you insert the upper pair of screws. Attaching the Cable Management Bracket The optional cable management bracket provides attachment points for organizing and routing cables. Attach the cable management bracket to the left or right rack-mount bracket using the screw provided. You can attach the cable management bracket to either the upper or the lower threaded hole. See Figure 9 for attachment locations.

Either edge may go up. Attach to either side of the chassis. Grounding the Chassis Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024 Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself. Statement 94 You must connect the chassis to a reliable earth ground; the ground wire must be installed in accordance with local electrical safety standards. For NEBS-compliant grounding, use size 6 AWG (13 mm2) copper wire and the ground lug provided in the accessory kit. Note This equipment is suitable for installation in Network Telecommunications Facilities and locations where the NEC applies. The equipment is suitable for installation as part of the Common Bonding Network (CBN). To connect the chassis to a reliable earth ground, perform the following steps: Step 1 Step 2 Strip one end of the ground wire to the length required for the ground lug or terminal (about 0.75 in. [20 mm] for the NEBS ground lug). Crimp the ground wire to the ground lug, using a crimp tool of the appropriate size. 14
