You can connect a Branch Gateway to a power source after you have mounted the Branch Gateway, optionally mounted and connected EM200 devices, media modules, and attached the supplementary ground conductor.
Procedure
Connect the power cable to the power connector on the Branch Gateway back panel.
Plug the AC power cable into an AC wall outlet.
When the Branch Gateway is switched ON, the PWR LED on the front panel comes ON. The CPU LED comes ON if the firmware is running.
At least one LED on each media module, except S8300 Server, comes ON and then goes OFF after about 20 seconds.
