Installing a Fan Module in a QFX5100 Device
The fan modules in a QFX5100 device are hot-removable and hot-insertable
field-replaceable units (FRUs): you can remove and replace them without powering off
the switch or disrupting switch functions.
CAUTION: Replacea failed fan module with a newfanmodulewithin 1minute
of removal to prevent chassis overheating. Before removing the fan module,
ensure you have a replacement fan module at hand.
NOTE: The fan module provides FRU-to-port or port-to-FRU airflow
depending on the switch product SKU you purchase. In legacy switches, or
switches with an LCD, this airflow is called front to back and back to front.
Before you install a fan module in a QFX5100 device, ensure that you have taken the
necessary precautions to prevent electrostatic discharge (ESD) damage (see “Prevention
of Electrostatic Discharge Damage” on page 263).
To install a fan module in a QFX5100 device (see Figure 70 on page 198 and
Figure 71 on page 198):
1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD
point on the chassis.
2. Taking care not to touch the connectors, remove the fan module from its bag.
3. Align the module with the open slot on the management panel of the chassis and
slide it in until it is fully seated.
CAUTION: Damage can occur if you attempt to install a fan module into
a chassis with a different airflow direction. Compare the switch product
