Chapter 3 Preparing Your Site for Installation

Site Planning

Avoid installing the Cisco 1000 Series Router in a congested rack and consider how the routing of cables

from other pieces of equipment in the same rack could affect access to the routers cards.

The front and top of the chassis must remain unobstructed to ensure adequate airflow and prevent

overheating inside the chassis.

Allow the following clearances for normal system maintenance:

• At the top of the chassis—At least 3 inches (7.6 cm)

• In the front of the chassis—3 to 4 ft (91.44 cm to 121.92 cm)

To avoid problems during installation and ongoing operation, follow these general precautions when you

plan the equipment locations and connections:

• Use the show environment all command regularly to check the internal system status. The

environmental monitor continually checks the interior chassis environment; it provides warnings for

high temperature and creates reports on any occurrences. If warning messages are displayed, take

immediate action to identify the cause and correct the problem.

• Keep the Cisco 1000 Series Router off of the floor and out of areas that collect dust.

• Follow ESD prevention procedures to avoid damage to equipment. Damage from static discharge

can cause immediate or intermittent equipment failure.

Locating for Proper Airflow

Ensure the location of the Cisco 1000 Series Router has enough airflow to keep the system operating

within the environmental characteristics and the air temperature is sufficient to compensate for the heat

dissipated by the system.

Avoid locating the Cisco 1000 Series Router in a location in which the chassis air intake vents could

draw in the exhaust air from adjacent equipment. Consider how the air flows through the Cisco 1000

Series Router. The Cisco 1000 Series Router airflow direction is front to back with ambient air drawn in

from the venting located on the chassis front sides.
