PTX1000 Environmental Requirements and Specifications

The PTX1000 must be installed in a rack. It must be housed in a dry, clean, well-ventilated, and
temperature-controlled environment.
Follow these environmental guidelines:
The site must be as dust-free as possible, because dust can clog air intake vents and filters, reducing the
efficiency of the PTX1000 cooling system.
Maintain ambient airflow for normal PTX1000 operation. If the airflow is blocked or restricted, or if the
intake air is too warm, the chassis might overheat, leading to the PTX1000 temperature monitor shutting
down the router to protect the hardware components.
Table 18 on page 52 provides the required environmental conditions for normal PTX1000 operation.
