Depending on the budget, refurbished Cyclades off ebay do the job well. Very solid and proven products, we still run few dated from 2003 … -Stan From: NANOG <nanog-bounces@nanog.org> On Behalf Of Alan Hannan Sent: Tuesday, September 18, 2018 9:37 AM To: NANOG <nanog@nanog.org> Subject: Console Servers 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! Thanks! -alan
