Step 3 Connect the AC power supply cord to the power supply.
Step 4 Plug the 3-prong end of the power cord into a standard electrical power outlet at the site. Power is
immediately supplied to the router. The router is meant to be left on at all times, and therefore, has no
power switch.
Warning This product relies on the building's installation for short-circuit (overcurrent)
protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240
VAC, 10A International) is used on the phase conductors (all current-carrying
conductors). The plug-socket combination must be accessible at all times because it
serves as the main disconnecting device.
Turn ON power for all other equipment, and wait for the devices to complete their startup processes.
Step 5
Caution To turn off the router when it is operational, disconnect the 3-prong end of the power cord
from the power outlet. To prevent electrical shock, do not disconnect the AC power supply
cord from the power supply while the router is operating.
Never defeat the ground conductor or operate the equipment in the absence of a suitably
Warning
installed ground conductor. Contact the appropriate electrical inspection authority or
an electrician if you are uncertain that suitable grounding is available.
