# Status LEDs A number of status LEDs are provided: * A green power LED that lights up when power is supplied to the board. * Two red T1 status LEDs: 'inner' and 'outer' (see Figure 3). A stable T1 connection has been established between the two on-board PHYs when the 'inner' status LED is flashing and the 'outer' status LED is solid on. * Two green LEDs on the RJ45 connector. An RJ45 connection has been established when the Data status LED is flashing and the Link status LED is solid on. ![](/files/-MaZJ6vUobGKEQgwtlPv) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
