I'm looking at switching from an APC UPS to a different brand after having had my third SU3000RM in a row blow up power transistors. I'm looking at the Cyperpower PR3000LCDRTXL2U. I see the PR3000E and the PR6000LCDRTXL5U listed as supported, but not the PR3000LCDRTXL2U. Howeverit seems likely that if the PR6000LCDRTXL5U is supported, the PR3000LCDRTXL2U ought to work as well. I've been running apcupsd, but if I go with the CyberPower unit I'll be installing NUT 2.7.4. Would anyone anticipate any possible issues here? Is there any practical benefit to getting the SNMP network card for it unless I plan to monitor it via SNMP, or can any monitoring and management I need to do be done perfectly well via serial, as on my APCs? Thanks. -- Phil Stracchino Babylon Communications phils at caerllewys.net phil at co.ordinate.org Landline: +1.603.293.8485 Mobile: +1.603.998.6958

I don't have specific experience with the RMCARD205 that they recommend on their website, but most vendors seem to be able to get SNMP right. If nothing else, SNMP card firmware is usually upgradeable. If you are mainly concerned about shutdowns when the UPS signals a low battery alert, then there is a good chance that the PR3000LCD* models are all supported equally well by the usbhid-ups driver. However, you may want to check the issue list if you are planning to depend on another threshold for shutdown: https://github.com/networkupstools/nut/issues?q=is%3Aissue+is%3Aopen+label%3A%22CyberPower+%28CPS%29%22 Also, you mentioned serial monitoring. I am not as familiar with serial CyberPower models, but take note of the support description here: https://networkupstools.org/docs/man/powerpanel.html#_support_status Most of the serial-connected CPS models have lower compatibility ratings due to this lack of public information: https://networkupstools.org/stable-hcl.html?manufacturer=Cyber%20Power%20Systems

Good information. I'll go ahead and add the SNMP card based on that recommendation. -- Phil Stracchino Babylon Communications phils at caerllewys.net phil at co.ordinate.org Landline: +1.603.293.8485 Mobile: +1.603.998.6958
