Phase Phase is used to describe the two main types of alternating current (AC) electric power produced by a utility, generator or UPS system. Single-phase power includes a single AC waveform, making single-phase equipment ideal for lower power density applications with per-rack power consumption levels up to approximately 2.8kVA (120V), 5kVA (208V) or 7.4kVA (230V). Three-phase power includes 3 AC waveforms, making 3-phase equipment better suited for intermediate and high-capacity applications with per-rack power consumption levels that surpass the practical energy limits of single-phase equipment.

PDU Type Basic PDUs All PDUs including Basic PDUs provide reliable rack-mount power distribution for data centers, server rooms, and network wiring closets. Metered PDUs Metered PDUs monitor load levels to avoid potential overloads via a LCD display. Monitored PDUs Monitored PDUs remotely monitor voltage, frequency, and load levels via a built-in network connection. Switched PDUs Switched PDUs can securely control individual outlets remotely to enable the rebooting of unresponsive equipment to minimize downtime. Auto Transfer Switch (ATS) PDUs ATS PDUs provide redundant power to connected equipment with separate primary and secondary power sources. Hot-Swap PDUs Hot-Swap PDUs have dual input power cables to enable live-replacement of select UPS systems with no power interruption to connected equipment.

The website says it is compatable with Lion but is ambiguous when it comes to Mountain Lion: 'The driver version 2.6.b5 can also be installed under OS X Mountain Lion but we have not verified that it actually works (we assume it does, though). If you successfully use this driver with OS X Mountain Lion, please let us know. If you see a warning during installation that the package has not been purchased from the Appstore and that the developer cannot be verified, the reason is that the package has not yet been signed by the manufacturer. You may install the package nonetheless by klicking once on the package while pressing the control key (ctrl). Then select 'Open' from the context menu.' Link to product page: I would attempt to reinstall the driver and see if works. In my opinion, if there was Lion support, I would have to think they would provide Mountain Lion support, but then again, that's just my opinion.

I just talked to Tripplite (owns Keyspan). The driver does not support 10.8 (ML) now.

They are 'probably' working on it according to tech support. No known date of support is known. My system uses two of these to control various systems. Both failed after the upgrade to ML.

After fooling around with it and then downloading the new beta drivers from the Tripplite website, the installer fails as it's optimizing the system. I presume it's some sandboxing issue and developer code that prevents it from working. I've even set the security to 'any developer' in security system preferences, but that doesn't appear to work. I really like Keyspan's serial adaptors.

They've worked flawlessly for years until now. I'm probably going to have to find another solution ASAP. I recently bought a Keyspan USA-19HS, installed the drivers I've found at triplite website rebooted and it works fine. Apple Footer.
