Routine Maintenance Procedures for the MX2020 Router
Purpose
For optimum router performance, perform preventive maintenance procedures.
NOTE: Some components, such as the craft interface, require no maintenance.
Action
•
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.
