The EAP600 cannot be set as a wireless repeater on both the 2.4GHz and 5GHz radios, because that will cause an IP conflict as the EAP600 will be detected twice by the router. The customer must choose which band will act as the backhaul. As illustrated below, when Repeater mode is selected by one band, the other band loses the Repeater mode option.
