If you must insert the MPC into a bag by yourself, first lay the MPC horizontally on a flat,
stable surface, sheet metal side down. Orient the MPC with the faceplate facing you.
Carefully insert the MPC connector edge into the opening of the bag, and pull the bag
toward you to cover the MPC.
Never stack an MPC under or on top of any other component.

For optimum router performance, perform preventive maintenance procedures.
NOTE: Some components, such as the craft interface, require no
maintenance.
Inspect the installation site for moisture, loose wires or cables, and excessive dust.
Make sure that airflow is unobstructed around the router and into the air intake vents.
Check the status-reporting devices on the craft interface—System alarms and LEDs.
Inspect the two air filters located just below the upper and lower PSMs, replacing them
every 6 months for optimum cooling system performance.
Inspect the air filter at the bottom rear of the router, replacing it every 6 months for
optimum cooling system performance. Do not run the router for more than a few
minutes without the air filter in place.
Inspect the air filter in the front of the middle cable manager of the router, replacing it
every 6 months for optimum cooling system performance. Do not run the router for
more than a few minutes without the air filter in place.
