TCX1000-RDM20 Environmental Requirements and Specifications
The TCX1000-RDM20 must be installed in a rack or cabinet. 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 TCX1000-RDM20 cooling system.
• Maintain ambient airflow for normal TCX1000-RDM20 operation. If the airflow is
blocked or restricted, or if the intake air is too warm, the chassis might overheat, leading
to the TCX1000-RDM20 temperature monitor shutting down the device to protect the
hardware components.
Table 16 on page 34 provides the required environmental conditions for normal operation
of the TCX1000-RDM20.
Table 16: TCX1000-RDM20 Environmental Tolerances
