The shelf life of polyurethane filter varies from two years to five years depending on
the storage conditions. Store in a cool, dry, and dark environment. Wrap the media in
plastic and store in an environment with relative humidity between 40%- 80% and
temperature between 40° F (4° C) to 90° F (32° C). Note that if the material flakes,
or becomes brittle when rubbed or deformed, it is no longer usable.

Removing the MX480 Air Filter
CAUTION: Do not run the router for more than a few minutes without the air
filter in place.
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 90 on page 235 ):
1.
Attach an 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.
