Hi All,
I tried to solve the problem without write message to the forum, but no luck.
I have three Mikrotik devices now.
RB951Ui-2HnD router, RBmAPL-2nD (mAP lite) and 260GS switch.
mAP lite I bought a few days ago and that made me unhappy.
I need extend my WiFi network to another building.
I laid UTP cable (no longer than 30 meters) and check this cable by my router. Just build test network. All works perfect.
I moved switch to new building, connected new cable to port #5 of router and port #1 of switch all worked good.
Switch received power from the router and the network worked perfectly.
After that I bought mAP lite and try to turn on this device with power over ethernet - the device does not turn on.
I connected it via USB power supply and it works perfectly.
I took an access point, and brought it to a router and try a shorter cable. It is also not successful.
I tried to use two power supply for the router 12V and 24V. No changes.
I checked specification for router and access point on the Mikrotik site and looks like all should works.
Any ideas?
