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

A QFX3008-I Interconnect device bottom air filter is located beneath the bottom fan tray and front panel display. There are two captive screws on either side of the air filter door that secure the air filter in the chassis.

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 the device components.

Before you remove an 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 bottom air filter from a QFX3008-I Interconnect device:

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

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

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 screws counterclockwise using your fingers. If you cannot easily unscrew the captive screws with your fingers, use the screwdriver.
3. Open the door, being careful to lower it gently, until it stops.
4. Pull on the air filter tab, located in the center of the filter, and slide the air filter straight out.
