Removing a Fan Module from an EX4550 Switch
The fan module is a hot-removable and hot-insertable field-replaceable unit (FRU)
installed in the rear panel of the switch: You can remove and replace it without powering
off the switch or disrupting switch functions.
Ensure that you have the following parts and tools available:
•
Phillips (+) screwdriver, number 2
•
An antistatic bag or an antistatic mat
•
A replacement fan module
To remove a fan module from the switch (see Figure 56 on page 201):
1. Place the antistatic bag or the antistatic mat on a flat, stable surface.
2. Loosen the screw securing the fan module by using the screwdriver.
WARNING: To avoid injury, do not touch the fan with your hands or any
tools as you slide the fan module out of the chassis—the fan might still
be running.
