ReadyNAS NV+ in standby draining Back-UPS ES550
Hi all, I suspect I'm going to be disappointed here but I have to ask, stranger things have happened.... I have two ReadyNAS NV+ units, one for media sharing and one exclusively for backup of ot...
If by "sleeping" you mean the disks are spun down, then the NAS should shut down gracefully when the UPS kicks in. (I use a CyberPower UPS, and have had this happen).
Andy has 2 NAS and apparently only one UPS. To get anything graceful to happen, one NAS has to detect the UPS state - which apparently is not working. The second NAS needs to monitor the first NAS over the network, since you can only connect one USB monitoring device to the UPS.
Therefore, the ethernet switch / router also has to be protected by the UPS, otherwise the second NAS will not get the power status it needs.
Anyway, the first step is to confirm that the UPS is properly cabled to the NAS. If the NAS won't detect it, then likely you will need a new UPS. There is a list here: http://www.readynas.com/?page_id=92 which includes your UPS. (It is missing others that work btw).
As far as capacity is concerned, you can always test that by unplugging the UPS during the day (with the NASes "asleep"), and see how long it lasts.
BTW, although I get the electrician's point, I think you might want to press him a bit harder. Maybe you can ask him to put the NASes on their own circuit w/o that protection (since the UPS is conditioning the power).
