PDUMH20ATNET
Overview
Tripp Lite Switched ATS / Auto Transfer Switch provides a redundant power option for single-corded network devices. Dual input cords support separate connection to PRIMARY and SECONDARY power sources. The ATS will normally maintain continuous output to all outlets as derived from the primary input cable. If the primary power source becomes unstable or fails altogether, the ATS will switch over to the secondary power source until the primary input is restored and stable. Switched PDU features include individually controllable output receptacles and built-in network interface. Super-fast switchover between primary and secondary power sources occurs within milliseconds. ATS functionality is supported by any two compatible AC power sources, regardless of phase angle, to support a variety of advanced redundant power networking applications. Enables fault tolerant hot-swappable UPS protection when used with a single UPS and fully redundant UPS protection when each cord is connected to a separate UPS system. In a two-UPS environment, the primary input cable must be supported by a full time sine wave UPS with zero transfer time. Tripp Lite SmartOnline series is highly recommended for use as the primary UPS in a two-UPS application. ATS configurations utilizing separate mains circuits, backup generators and even separate utility power grid feeds are fully supported. On-board ATS processor constantly evaluates power quality on both input sources to prevent transfer to the secondary source when unavailable or of lower quality than the primary source. Front input LED's display primary or secondary power availability.

Comments about Tripp Lite 1.9kW Single-Phase ATS / Switched PDU 120V (16 5-15/20R) 2 L5-20P / 5-20P Inputs 2 12ft Cords 1U Rack-Mount:
The unit seems to work well. Just installed in a new data center space. Network interface has some challenges. Main one was the document saying the access credentials to get started are "admin" and "admin".
A web search uncovered the "root" and "TrippLite" credentials that should have been listed, with which I got into the RS-232 interface and set up some other accounts and passwords.
The Web GUI requires Java. It does not work with the latest Java if you're on a Mac. Better have VMware handy and a Windows virtual machine as you'll need those. Oh, and the Java Applets aren't signed properly, so you will have to dial down your Java security settings.
It's really too bad the interface isn't built with present web technology such as JQuery/AJAX/JavaScript. That'd work across browsers and avoid all this mess with Java. It'd result in a better interface, too.
The command line interface via TELNET or SSH works reasonably well. I'm guessing that's what I'll use most often.

I wish I could experience the reliability of the other reviewer. Whenever I need to use the network connected features of this product I cross my fingers and hope it works.
Comments about Tripp Lite 1.9kW Single-Phase ATS / Switched PDU 120V (16 5-15/20R) 2 L5-20P / 5-20P Inputs 2 12ft Cords 1U Rack-Mount:
I've been using these devices for a number of years and they've always provided good reliable service. Easy to install and configure, easy to use web GUI. And since every device in my data center runs through one, the SNMP capabilities allow me to see track my entire power utilization in one centralized place.
One caveat. I'm normally a text-UI guy, but this one is so counter-intuitive that I exclusively use the web interface. I once shut down an entire PDU through the text UI when I was just trying to power cycle one device. That event was what taught me to disable the text UI and just go with the web.
