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.
Site Planning Checklist
Use the following checklist to perform and account for all the site-planning tasks described in this chapter:
• The site meets the environmental requirements.
• The site air conditioning system can compensate for the heat dissipation of the Cisco ASR 1000 Series
Routers.
• The floor space that the Cisco ASR 1000 Series Routers occupy can support the weight of the system).
• Electrical service to the site complies with the requirements.
• The electrical circuit servicing the Cisco ASR 1000 Series Routers complies with the requirements).
• Consideration has been given to the console port wiring, and limitations of the cabling involved, according
to TIA/EIA-232F.
• The Cisco ASR 1000 Series Router Ethernet cabling distances are within limitations.
• The equipment rack in which you plan to install the Cisco ASR 1000 Series chassis complies with
requirements.
• Careful consideration has be given to safety, ease of maintenance, and proper airflow in selecting the
location of the rack.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, occurs when electronic cards or components are improperly handled
and can result in complete or intermittent failures. The performance routing engine (PRE), and all line cards
consist of a printed circuit card that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding
and connectors are integral components of the carrier. Although the metal carrier helps to protect the cards
from ESD, use an antistatic strap each time you handle the modules. Handle the carriers by the edges only;
never touch the cards or connector pins.
Always tighten the captive installation screws on all system components when you are installing them.
These screws prevent accidental removal of the module, provide proper grounding for the system, and
help to ensure that the bus connectors are properly seated in the backplane.
