Hello!
Recently we had a "broken" Phone 30, which didn't communicate with the IPO. (blinking green light, then after DTE - solid red light and TFTP Poll timeouts)
Now i'm happy to announce that these modules can be repaired, the communication IC should be replaced by a person who is capable of soldering smd ics. So if others have expansion modules that doesn't communicate with the IPO, maybe the solution is simple and you shouldn't throw the module out.
