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.
Secure the supply cable to the rack framework or a similar object, to ensure 
that the connections are isolated from any force applied to the cable.
