Both sides of the gateway have air intake vents, which attract dust. For optimum performance of
the gateway, perform the following preventive maintenance procedures regularly:
Warning: Do not insert any metal object, such as a screwdriver, or place your hand into an open
slot when the gateway is powered on. Remove jewelry (including rings, necklaces, and watches)
before working on the equipment that is connected to power lines. These actions prevent electric
shock and serious burns.
Inspect the installation site for moisture, loose wires or cables, and excessive dust. Make sure that
airflow is unobstructed around the gateway and into the air intake vents.
Check the LEDs on the front panel for the status of the ports and the power supply of the
gateway. For more information on LEDs, see "BX7000 Multi-Access Gateway Overview" on
page 3.
Periodically inspect the site to ensure that the grounding and the power cords connected to the
gateway are securely in place and that there is no moisture accumulating near the gateway.
To maintain cables:
Use the cable management brackets to support cables and prevent cables from dislodging or
developing stress points.
Place excess cable out of the way in the cable management brackets. Do not allow fastened
loops of cable to dangle from the connector or cable management bracket as this stresses the
cable at the fastening point. Put fasteners on the loops to help maintain their shape.
Keep the cable connections clean and free of dust and other particles, which can cause drops in
the received power level. Always inspect cables and clean them if necessary before connecting
an interface.
The following guidelines apply specifically to fiber-optic cable:
