Maintenance Safety
Summit X440 Series Switches Installation Note
6
●
Plug power cords only into properly grounded electrical outlets to help prevent electrical shock and
to comply with international safety standards.
●
Use only power cords that are certified for use within the country of use. Do not attempt to modify
AC power cords.
●
Make sure the voltage and frequency of your power outlet match the system electrical ratings for the
equipment. The building and/or power source must provide overload protection.
●
Use a surge suppressor, line conditioner, or uninterruptible power supply to protect the system from
momentary increases or decreases in electrical power.
●
Summit X440 series switches do not have switches for turning the unit on and off. Remove the wall
plug from the electrical outlet to disconnect the power from a Summit X440 series switch. Make sure
that this connection is near the equipment and is easily accessible for quick disconnect.
WARNING!
Make sure that the source outlet is properly grounded according to the country’s local electrical
requirements before plugging the AC supply power cord into a power supply.
