I have exhausted my search engine skills trying to locate this software and have had no luck. I've tried, Google, Bing, DuckDuckGo, Blekko, Yahoo, and HP's own website search. They all turn up the same useless results.
I've encountered another problem, this time with the 3com Central Configuration Manager which appears to be the only way to configure the Intellijacks. The version of CCM I have is 2.4.100. It can configure the Intellijack with firmware version 2.4.100 just fine. However, I have another Intellijack that has firmware version 2.4.13 that CCM throws any error at when trying to apply configuration changes. Of course, there is no trace of this software anywhere on HP's website. So far, HP support has been silent on the issue.
