Description
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.
• Make sure 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) that you are using.
Routine
Maintenance
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
cooling system
To maintain the power supply on the services gateway:
•
Make sure 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.
