Installing the Router

Note Cisco 1800 series routers are normally ordered with modules and interface cards. Before you remove or install any
modules or interface cards, refer to the documents that accompany those items or to the online Cisco 1800 series
hardware installation documentation at the following URL:
http://www.cisco.com/univercd/cc/td/doc/product/access/acs_mod/1800/hw/index.htm
You can set any Cisco 1800 series router on a desktop. See the applicable instructions in the following section:
•Installing the Router on a Desktop, page 10
Caution To prevent damage to the chassis, never attempt to lift or tilt the chassis by the plastic panel on the front. Always
hold the chassis by the metal body.

Installing the Router on a Desktop

The Cisco 1841 router is shipped with the rubber feet attached to the chassis.
Caution Your chassis installation must allow unrestricted airflow for chassis cooling. For placing on a desktop, keep at least
one inch 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 top of each other.

Grounding the Chassis

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
