Installing a Fan Module in a TCX1000-RDM20
The fan modules in a TCX1000-RDM20 are hot-removable and hot-insertable
field-replaceable units (FRUs)—you can remove and replace them without powering off
the TCX1000-RDM20 or disrupting routing functions.
CAUTION: Replace the fan module within 30 seconds of removal to prevent
chassis overheating. Before removing the fan module, ensure that you have
a replacement fan module available.
NOTE: The fan module provides airflow out, which is also known as
front-to-back airflow.
Before you install a fan module in a TCX1000-RDM20, ensure that you have taken the
necessary precautions to prevent electrostatic discharge (ESD) damage (see
“Prevention
of Electrostatic Discharge Damage” on page 178 ).
