Grounding the Router | Cisco Systems 3800 Series guide

Grounding the Router

Install the router in the rack, using two screws for each side. Rack-mounting screws should be supplied with the rack; they are not provided with the router.

Caution Be sure to leave space above and below each router in a rack, to allow for cooling air circulation.

Tip Start the lower pair of screws first. Rest the brackets on the lower screws while you insert the upper pair of screws.

Attaching the Optional Cable Management Bracket

The optional cable management bracket (Cisco 3825 router only) 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 lower threaded hole. See Figure 7 for attachment locations.

Grounding the Router

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
