Removing a Fan Tray from an EX3200 or EX4200 Switch

EX3200 and EX4200 switches have a single fan tray on the rear panel. The fan tray is a hot-removable and hot-insertable field-replaceable unit (FRU): 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

To remove a fan tray from an EX3200 or EX4200 switch (see Figure 1 and Figure 2):

1. Place the antistatic bag or the antistatic mat on a flat, stable surface.
2. Loosen the screw or screws securing the fan tray by using the screwdriver.

   Warning: To avoid injury, do not touch the fan with your hands or any tools as you slide the fan tray out of the chassis—the fan may still be running.

3. Grasp the handle on the fan tray and pull firmly to slide the fan tray halfway out of the chassis.
4. When the fan stops spinning, slide the fan tray completely out of the chassis.
5. Place the fan tray in the antistatic bag or on the antistatic mat placed on a flat, stable surface.

Note: When a fan tray is removed, Fan/Blower is Absent is logged in the system log and the system raises a minor alarm.
