Routine Maintenance Procedures for the JRR200 Route Reflector
For optimum performance of the JRR200 route reflector, perform the following preventive
maintenance procedures regularly:
• Inspect the installation site for moisture, loose wires or cables, and excessive dust.
• Make sure that airflow is unobstructed around the JRR200 route reflector and into the
air intake vents. Make sure that all power and grounding cables are arranged so that
they do not obstruct access to other device components.
• Check the status LEDs on the front panel of the JRR200 route reflector.
• Periodically inspect the site to ensure that the grounding and power cables connected
to the JRR200 route reflector are securely in place and that there is no moisture
accumulating near the JRR200 route reflector.
