| [title] Test the TVS diode | |
| [* orange] The TVS diode, marked D6 on the PCB, is located between the antenna and a large IC on the RJ45 port side of the board. | |
| - | [* |
| - | [* red] Use a multimeter or ohmmeter to test whether the diode has shorted. A shorted diode will read less than 1 Ohm in both directions. A working diode will have significantly higher resistance in one direction than the other. |
| + | [* icon_note] It is a 24V uni-directional TVS diode with J leads (SMBJ24A) made by Littlefuse. Note the location of the white bar on the diode, as it indicates its orientation. |
| + | [* red] Use a [product|IF145-035-7|multimeter] or ohmmeter to test whether the diode has shorted. A shorted diode will read less than 1 Ohm in both directions. A working diode will have significantly higher resistance in one direction than the other. |
| [* icon_note] If the diode is not shorted, then there may be another issue, and proceeding further may not help resolve the problem with your access point. |
