I have a Ethernet Surge Protector PoE Gigabit LAN Thunder RJ45 CAT5 CAT5E CAT6 1000mbs
by Everstar P/N ESWA-3310C6. It has "In" and "Out" posted on the two ends. See the attached picture.
Is "In" for the POE in and "Out" for the POE out?
Is the "In" for the source of the potential shock?
In my case, I am trying to prevent a shock from an outdoor access point getting to my indoor router.
