Juniper Networks MX480 - Manual (Page 188)

CAUTION: Always keep the air filter in place while the router is operating,
except during replacement. Because the fans are very powerful, they could
pull small bits of wire or other materials into the router through the unfiltered
air intake. This could damage the router components.
To remove the air filter (see Figure 79 on page 164 ):
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. Loosen the captive screws on the air filter cover.
3. Remove the air filter cover.
4. Slide the air filter out of the chassis.
