Re: [AFMUG] missing part on Canopy SM
Ken, If that part was damaged (and then removed on purpose) there could be damage to the Ethernet Transceiver itself or a few of the other parts that support the transceiver. Obviously, send it back. For grins, you might try setting your computer interface to 10Mbit just to see what it does Paul From: Af [mailto:af-bounces+paulm=pdmnet@afmug.com] On Behalf Of Ken Hohhof via Af Sent: Sunday, September 28, 2014 12:13 AM To: af@afmug.com Subject: Re: [AFMUG] missing part on Canopy SM Could be, but it looks like it was cleanly desoldered.

Re: [AFMUG] missing part on Canopy SM
Could be, but it looks like it was cleanly desoldered. Seeing up close is not one of my superpowers though, not for quite awhile now. I was just trying to configure it at the office. Ethernet bounces up and down, and LEDs don’t seem to go through the regular sequence. I did once get into it at 192.168.1.1 which is strange because it was supposed to be defaulted, NAT was enabled.
