| [title] Test the TVS diode | |
| [* orange] The TVS diode is located between the antenna and a large IC on the RJ45 port side of the board. | |
| - | [* orange] The diode in question is a LittleFuse 24V uni-directional TVS diode, with J leads (SMBJ24ALFCT-ND). Note the location of the white bar on the diode, towards the antenna. |
| + | [* orange] The diode in question is a LittleFuse 24V uni-directional TVS diode, with J leads (SMBJ24A). Note the location of the white bar on the diode, towards the antenna. |
| + | [* black] Use a multimeter or ohmmeter to test that the diode has indeed shorted. It should read significantly higher resistance in one direction relative to the other. A shorted diode will read less than 1Ohm in both directions. |
