and then the Juma amplifiers, it looks like I sent 12V to J11 and popped
a hole in Q2. All diodes except D23, D25-D28 went off. No sign of any
connectivity to the network on the switch. I ordered a replacement 2N7002K for
Q2 from DigiKey yesterday but I don't think that alone would knock out the
TCP/IP connectivity and the status diodes . Looking for troubleshooting kick
start. I've been taking voltage measurements on the board from the schematics
but got to thinking there may be some firmware I zapped which needs reloading
through a method not accessible when the TCP/IP route is blocked. I've done a
complete inspection of the top and the bottom of the board and this is the only
sign of visible damage.<o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Thanks in advance for any advice,<o:p></o:p></p><p class="MsoNormal">Dave (W4DJW) <o:p></o:p></p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">:-(<o:p></o:p></p></div></div></blockquote></div><br></div></body></html>
