Installing A Fan Module In A Qfx10002 - Juniper QFX10002 Hardware Manual

Installing a Fan Module in a QFX10002

Before you install a fan module in a QFX10002 device, ensure that you have taken the necessary
precautions to prevent electrostatic discharge (ESD) damage (see
Damage" on page 189).
The fan modules in QFX10002 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: Replace a failed fan module with a new fan module within 1 minute 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 airflow out, which is also known as
legacy switches, or switches with an LCD, this airflow is called front-to-back airflow.
To install a fan module in QFX10002 models :
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 with the label right-side up to ensure the correct orientation.
See Figure 45 on page 125
NOTE: The QFX10002-60C uses a different fan module that has a different orientation than
the QFX10002-72Q and QFX10002-36Q.
4. Slide the module into the bay until it is fully seated.
5. Using a Phillips screwdriver, turn the locking screw until it is tight.
