UPS recommendation for two NAS's: Pro Pioneer 6 and RN316

Question

Hello,I have two units in the same area for my home office:ReadyNAS Pro Pioneer 6 running 4.2.27ReadyNAS RN316 running 6.2.4I need a new UPS and am wondering the best choice. I am wondering if it works to get one UPS and integrate all together or if it's better/easier to just get two units. I will also seek to add three more components to the UPS; Motorola SB6141 cable modem, R8000 wifi router, and Cisco SR2016T network switch. That might protect computer work for short-duration power outages, but for longer outages I'm interested in automatically turning everything off (including the UPS) so the UPS battery isn't uselessly drained. I'm more concerned with lightning-induced power surges than power interruption... thinking that a UPS is a good help with this but will also be looking into whole-house protection. One or two UPS units? Which ones? I'm not married into getting any particular brand. Can the UPS turn itself off after the NAS's are powered off?I'm also in the hunt for Ethernet surge protection devices. Besides surges entering the cable modem, I also run Ethernet cables thru the outside wall of my office, outdoors to the attic and then down to the living room to feed the smart TV and stereo server. I reckon those two long cables could act as good antennas to pick up surges from lightning activity.Thanks!

If you do use a single UPS for the two NAS you do need to be sure that you protect the switch they share as well.

With this amount of kit I think I'd go with two UPS though. Many UPS will also filter ethernet, so you can potentially use two UPS to filter both the ethernet lines at one egress. Many normal surge protectors also filter ethernet and coax. Obviously you need to protect the TV ethernet entrance too.

I use Cyberpower (most recently CP1500AVRLCD), and they have worked well for me. Though I have not yet experienced lightening...

I'm OK with getting two separate UPSs, one each for my two NASs.

Three Questions:
(1) Are there some that are reputedly better for lightning surge suppression?
(2) Do I want to get a pure sine output UPS? I see that some are simulated sine, some are stepped approximation, etc.
(3) Can some be programmed to shut themselves off after the NAS is gracefully powered down? I'm thinking that doing this will save on battery life, but correct me if this is wrong.

StephenB, you use the CP1500AVRLCD, but there's the pure-sine wave CP1500PFCLCD. Yes it's more money but still quite affordable and if it avoids problems then the money isn't a huge difference or factor. I'd probably more concerned with the amount of time and burnt brain cells getting these set up.

Thanks!

I haven't seen anything specific on models good for lightning. I suspect none of them will protect against a direct or near-direct strike. I'd expect them to handle less extreme cases, but I haven't ever experienced them.

I don't have a lot of power failures, but I have had some since I first started using Cyberpower. I haven't had any problems with the any of my equipment, including my 5 ReadyNAS. Though if you prefer a pure-sine wave UPS, then go for it.

I don't see how turning off the UPS after power down would save its battery life. I think the critical power alert that shuts down the NAS is generally 10% of capacity or less, so the battery essentially needs a full recharge anyway.

I talked with CyberPower and the tech guy affirmed that the pure sine is only needed for the new energy-star power supplies... I don't have any of those yet. Also asked about the surge suppression levels and was told that the units become sacrificial at higher levels (including the ethernet and coax protection) so you should be protected by all and his reading showed that anything over 400 joules was ok for durability.

Comparing:
Pure sine: CP1500PFCLCD; $210; 1,030 joules surge suppression
Stepped sine: CP1500AVRLCD; $138; 1,500 joules surge suppression
Stepped sine: APC BR1500G; $163; 354 joules surge suppression

Lastly... I have an old-school APC Smart-UPS 1000VA SUA1000 true sine wave beast who's battery is long gone, but I can get a replacement battery for $65. Maybe that's the route to go? It does have a USB port in the back... (viewtopic.php?f=88&t=21722&p=280368&hilit=SUA1000#p280368)

Thanks again!

Update:&nbsp;I went the easiest route for now on the UPS's: &nbsp;replaced the batteries on my old, pure-sine SUA1000 UPS for $60. &nbsp;That unit has some surge protection, so I'm running directly from that. I have the UPS plugged into the RN316 vis USB and then the Pro Pioneer 6 monitoring the IP address of the RN316. &nbsp;I very much stumbled around with the settings and that's what I could get to work. &nbsp;I'm not sure why but I&nbsp;do get relatively frequent "UPS communication error" messages from the Pro Pioneer. &nbsp;??? &nbsp;Any ideas? &nbsp;Below are two screenshots of the setup.&nbsp;I bought a more effective surge protector to use to protect my home TV &amp; stereo from SurgeX. &nbsp;I went around with tech support and bought a SX-DS-156... I had thought that space was an issue but in reality it is not and I'd consider the SA-966 if I need another (i.e. to plug in the SUA1000 for real protection).&nbsp;For broadband cable I installed: &nbsp;L-Com AL-FFFF-9 &nbsp;(cheap)And for the main breaker box: &nbsp;Eaton CHSPT2ULTRA (cheap enough)For CAT6 lines: L-Com&nbsp;RMSP-CAT6T-12 (not cheap)Also because some CAT6 lines run outside the house between floors, I added a second CAT6 surge supressor at the far end I added a APC PRM4/PNETR6 because I got one cheap...&nbsp;&nbsp;Here's the UPS settings for the two ReadyNAS units:
