Juniper PTX10008 Hardware Manual page 150

Maintain ambient airflow for normal router operation. If the airflow is blocked or restricted, or if the
intake air is too warm, the router might overheat, leading to the router temperature monitor shutting
down the device to protect the hardware components.
Table 49 on page 152 provides the required environmental conditions for normal router operation.
