1. Check that the power supply and cable is not live.
Ensure the circuit breaker for the supply circuit is in the off position, and the
PSU run/standby button is in the standby position. When the run/standby
button is not depressed, it is in standby.
2. Plug the supply cable into the router.
Plug the provided DC power cord into the power inlet on the faceplate of
the PSU. The plug is keyed with locking tabs, and will only fit in the inlet one
way. The following figures show the polarity of the supply cable and the
power inlet.

3. Secure the cable.
