Installing a Bottom Air Filter in a QFX3008-I Interconnect Device

A QFX3008-I Interconnect device bottom air filter is located beneath the bottom fan tray and front panel display. Two captive screws on either side of the air filter door 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 device components.

Before you install a bottom 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 install a bottom air filter in a QFX3008-I Interconnect device:

• Electrostatic discharge (ESD) grounding strap

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
2. If the air filter door is closed, unscrew the captive screws on each side of the air filter door, and pull the door open.
3. Slide the air filter into the chassis. The air filter has a label indicating which side should be facing up.
4. Close the air filter door, and tighten the captive screws on each side of the air filter door.
