[MT-AU Public] POE Interface and Disable command

Stupid question perhaps....but, I have access into a CPE via the wireless link, and in good Mikrotik fashion the router I have on the other side of the CPE, also a MT, has auto negotiated at 10M FULL, so I need to disable the interface and re-enable it from the CPE side, but, the CPE is powered using POE on that same interface. Sooo, if I disable the Ethernet interface will it lose power or is the POE totally separate from the data side of the interface, I am pretty sure it is but before dropping this interface I Want to be 100% sure as it's a long drive to re-enable it J Thanks Paul
