Between the two of us, we can come up with a good one, maybe.
We had a PM2ER-30 sent out as a replacement for one with a flaky WAN
port. The replacement has not only a totally inoperative WAN port, but
the top board (Ports 20-29) won't pass any data at all. The handshake
lines work, we can reset the modems, etc., but no data flow. And, it
isn't the board, as I exchanged it with the known good one from the first
PM.
I now have, in a POP that was intended to have a single PM2ER, the
following in order to get the same functionality:
One IRX-111 (sent to bypass the first problem of a flaky WAN port)
One PM2ER-30 (with inoperative WAN port and inoperative ports 20-29)
One PM2ER-20 (intended for another site, also with flaky WAN port, to
accommodate the last ten modems)
One ethernet hub
As well as the original PM2ER-30 awaiting return to Livingston once I get
through to their tech support folks again.
