I just use a Raspberry Pi with USB to Serial adapters or old servers with PCI(-E) 8 port serial cards. They make it so easy to adapt to any environment, and it phones home to my conserver ( gateway. The total cost for hardware is less than $150.

My favorite are the lantronix SLC console servers.  Fairly bullet-proof, they are one of those devices that just work.  Can usually be picked up used ~$300 for 32 or 48 port varieties in good condition if you aren’t in the biggest hurry.

I'd like your input on suggestions for an alternate serial port manager.

Long ago I used Cisco 2511/2611 and was fairly happy.  A little later I used portmaster and was less so.  Recently I've been using Opengear and they work fairly well but the price is fairly high.   I use the CM7100 and IM7100.

General specs I'm looking for are:

 * 8 to 48 or more rs232 serial ports on rj45
 * nice-to-have software selectable pinouts (cisco v. straight)
 * gig-e ethernet port (100mbps ok)
 * 1U form factor
 * redundant AC power
 * access physical serial connections via local port #
 * access physical serial connections via local IP alias (nice to have)

Can you recommend a serial port server/concentrator that I could use in place of opengear for a better value and/or lower cost?

I'm just ignorant about the current market for serial port concentrators and so far web searches have not revealed ideas, so your input is appreciated!
