Removing a Side Air Filter from a QFX3008-I Interconnect Device

The QFX3008-I Interconnect device has eight side air filters located in each of eight side fan tray modules. A tab on the air filter facilitates the removal and installation of the air filter.

Caution: Do not run the device for more than 2 minutes without the air filter in place.

Caution: Always keep the air filter in place while the device is operating, except during replacement. Because the fans are very powerful, they could pull small bits of wire or other materials into the device through the unfiltered air intake. This could damage device components.

Before you remove a side air filter, ensure that you understand how to prevent ESD damage. See Prevention of Electrostatic Discharge Damage.

Ensure that you have the following parts and tools available to remove a side air filter from a QFX3008-I Interconnect device:

• Electrostatic discharge (ESD) grounding strap
• Replacement air filter
• Phillips (+) screwdriver, number 2

To remove an air filter from a QFX3008-I Interconnect device (see Figure 1 and Figure 2):

1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the chassis.
2. Unscrew the captive screw, located on each cover panel, counterclockwise using your fingers. If you cannot easily unscrew the captive screw with your fingers, use the screwdriver.
3. Hold the screw on the cover panel with one hand while holding the handle with the other. Pull firmly on the screw to detach the cover panel.
4. Pull the air filter tab to the side and slide the filter out of the fan tray module.
