and damage to the system.
Statement 378
Note • Do not stack anything on top of the router.
•Do not cover or obstruct the router vents located on both sides and top of the routers; otherwise,
overheating could occur and cause damage to the router.
•Place router in ventilated area to avoid local air heating.
Caution Do not cover or obstruct the router vents located on both sides of the router; otherwise, overheating could
occur and cause damage to the router.
Caution Do not place anything on top of the router that weighs more than 10 pounds (4.5 kilograms), and do not
stack routers on a desktop. Excessive weight on top of the router could damage the chassis.
Caution Do not install the router or power supplies next to a heat source of any kind, including heating vents.
Caution The top surface of the router is hot since heat is dissipated through the top. Do not keep any object in
direct contact with the surface for a prolonged period.
Installing on a Table
To install the router on a table or other flat horizontal surface, firmly place the router on a table or other
horizontal surface. Keep at least 1 inch (2.5 cm) of clear space beside the cooling inlet and exhaust vents.
Connect the chassis to a reliable earth ground. For the chassis ground connection procedures, see the
“Installing Cisco 890 Series in a Rack” section on page2-52.
Note Do not place anything on top of the router.
Mounting on a Wall
The Cisco 860 series, 880 series, and 890 series ISRs have mounting holes on the bottom of the chassis
for mounting the unit on a wall or other vertical surface.
