Maintaining the Air Filter on the SRX5400 Services Gateway
Purpose
For optimum cooling, verify the condition of the air filters.
Action
Regularly inspect the air filter. A dirty air filter restricts airflow in the unit, impeding the
ventilation of the chassis. The filter degrades over time. Periodically replace the filter
•
in use, as well as spares. We recommend that you replace the filter every six months.
Discard used filters, do not attempt to clean and reuse them.
CAUTION:
Always keep the air filter in place while the services gateway is
operating. Because the fans are very powerful, they could pull small bits
of wire or other materials into the services gateway through the unfiltered
air intake. This could damage the services gateway components.
•
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.

Maintaining the Fan Tray on the SRX5400 Services Gateway
Purpose
For optimum cooling, verify the condition of the fans.
Action
Monitor the status of the fans. A fan tray contains multiple fans that work in unison to
cool the services gateway components. If one fan fails, the host subsystem adjusts
•
the speed of the remaining fans to maintain proper cooling. A major alarm is triggered
when a fan fails, and a minor alarm and major alarm is triggered when a fan tray is
removed.
