Cisco ASR 903 Installation Guide

The tables below provide and overview of the operating ambient temperature limits for different fan tray and
interface module combinations. These values are specified for side-to-side airflow configuration.
The temperature range could further be restricted by the optical modules are used in the router.
Note
If you remove the fan tray from the system, the node thermal shut down is based on ASIC temperature and
not based on the timer value, from release 16.6.x and later.
