Jumper settings are only read during power up. If a jumper position is changed, power must
be cycled for the change to take effect.
Mounting
N
2 can be mounted in many standard two-gang electrical boxes. A deep box (minimum
ODE
2.125 inches) is required for the electronics and to allow space for the network connection.
Raco model 683SP is an example of such a box.
Care must be taken to ensure that no part of the electronics are touching the box. Do NOT

Powering
N
2 is powered using Power Over Ethernet (PoE). This simplifies installation by allowing the
ODE
installer to pull a single CAT5 (or higher) cable to N
Ethernet signals. A PoE switch or a PoE power injector must be used to provide power to
