Connecting the Chassis to Ground

Connecting the Cisco uBR10012 router chassis to earth ground is required for all DC powered installations. Have the recommended tools and supplies available before you begin this procedure (see Table 3-2).

Warning The importance of proper grounding cannot be overemphasized. It will minimize the potential for damage to your system and maximize safety at the system site. We recommend you consult a licensed electrician or your local electric utility company if you have any questions. Statement 269

Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046
