Cisco Systems 2800 manual Grounding the Chassis, Installing the Router on a Desktop

Caution The router must be mounted with the power connections oriented downward. Failure to do so could present a fire hazard.

Installing the Router on a Desktop

If you install your Cisco 2800 series router on a desktop, observe the following precautions:

Note For Cisco 2801 routers, attach the four rubber feet to the bottom of the chassis.

Caution Your chassis installation must allow unrestricted airflow for chassis cooling. For placing the router on a desktop, keep at least 1 inch (2.54 cm) of clear space beside the cooling inlet and exhaust vents.

Caution Do not place any items that weigh more than 10 pounds (4.5 kilograms) on top of the chassis, and do not stack routers on a desktop.

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

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).

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.

•For NEC-compliant grounding, use size 14 AWG (2 mm2) or larger copper wire and an appropriate user-supplied ring terminal with an inner diameter of 1/4 in. (5-7 mm).

•For EN/IEC 60950-compliant grounding, use size 18 AWG (1 mm2) or larger copper wire and an appropriate user-supplied ring terminal.

Warning	This equipment needs to be grounded. Use a green and yellow 14 AWG ground wire to connect the host to earth
	ground during normal use. Statement 190

To connect the chassis to a reliable earth ground, perform the following steps:

Step 1 Strip one end of the ground wire to the length required for the ground lug or terminal.

•For the NEBS ground lug—approximately 0.75 inches (20 mm)

•For user-provided ring terminal—as required
