Cisco Systems ASR 903 manual Locating for Proper Airflow, 2-17

Chapter 2 Preparing for Installation

Site Planning

•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 about high temperature and creates reports on other potentially dangerous occurrences. If warning messages are displayed, take immediate action to identify the cause, and correct the problem.

•Keep the Cisco ASR 903 Router off 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 that the Cisco ASR 903 Router location 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. For more information, see “Air Flow Guidelines” section on page 2-11.
