Routine Maintenance Procedures

To maintain optimum performance of the services gateway, you should regularly perform the following preventive maintenance procedures:

• Inspect the installation site for moisture, loose wires or cables, and excessive dust.
• Ensure that airflow is unobstructed around the device and into the air intake vents.
• Check the Status LED on the front panel of the device and on the Mini-Physical Interface Module (Mini-PIM) you are using.

Maintaining the Cooling System

The services gateway cooling system works to maintain an optimal temperature for the device. If the fan controller fails, the device temperature will exceed the maximum working temperature and the device will fail. Ensure that you maintain the recommended clearances behind the device to enable the cooling system to function optimally.

Maintaining the Power Supply

To maintain the power supply on the services gateway:

• Ensure that the power and grounding cables are arranged so that they do not obstruct access to other device components.
• Periodically inspect the site to ensure that the grounding and power cables connected to the device are securely in place and that there is no moisture accumulating near the device.

Caution: We recommend using a surge protector for the power connection.

Maintaining the Air Filter

• Periodically replace the filter in use. We recommend that you replace the filter every six months as a dirty air filter restricts airflow in the unit, reducing the ventilation of the chassis. The filter degrades over time.
• Store spare air filter in a dark, cool, and dry place. Storing air filter at higher temperatures, or where they can be exposed to ultraviolet (UV) radiation, hydrocarbon emissions, or vapors from solvents, can significantly reduce their life.

Note: Always keep the air filter in place while the device is operating. Because the fans are very powerful, they could pull small bits of wire or other materials into the device through the unfiltered air intake. This could damage the device components.
