2 Connect the other end of each EPS-160 power supply cord to the Extreme switch (see Figure 220).
This connector end can only be inserted into the switch with the end marked TOP facing up.
If your switch shipped with a metal cover plate over the redundant power input connector, remove the cover.
The redundant power input connector on the rear of the switch contains high energy and is a burn hazard. Use
care when connecting the redundant power supply cord to the rear of the switch.

3 Using the supplied cord, connect the AC cord to the AC supply for each unit.
For countries other than the USA, you might require a different AC cord that is not supplied. Contact your sales
representative for the appropriate cord type and for information regarding the voltage and current requirements of
the power supply.
Consider all of the equipment that is connected to the power supply circuit to ensure that the circuit is not
overloaded. Use proper overcurrent protection, such as a circuit breaker, to prevent overcurrent conditions.
The switch and its redundant power source should not be plugged into the same circuit breaker.
The PSU-E LED on the front of the EPS-160 should be solid green to indicate that it is ready.
