ups

Hello all I am new here , so I hope i do not post this in the wrong space. also, thank you in advance! I've had a UPS (Uninterruptible Power Supply) running for a while now, keeping the power on for my NAS (Network-Attached Storage), and something quite unusual happened a few weeks ago. The...

Hello, The short version - I'm looking for a UPS system that isn't going to be *too* expensive and will allow me to sustain ~600W or so of power from batteries without overheating no matter the runtime, as I plan to hook the UPS up to external deep cycle batteries. If I could find a good...

Hi, I currently have the following server hardware, for which I'm searching for an UPS: SuperStorage 6027R-E1R12T Motherboard Supermicro X9DRH-7TF 2x Intel Xeon E5-2630V2 128Gb ECC RAM (8x Samsung 16GB 2Rx4 DDR3 1600MHz PC3-12800R ECC RDIMM RAM REG M393B2G70BH0-CK0) LSI SAS 9207-8i KIT 8-Port...

So I finally upgraded from a stand alone UPS to a nice rack mount one. I got a SUA2200RM2U off ebay without batteries. I had to put a lot of work into it, ordered the batteries, repaired the power cable, I also got the AP9631 Network Management Card. Today it all comes together and its...

Hi Everyone, There really isn't a subforum for UPS:es and other power solutions, so I decided to post here. I bought a couple of APC SMT1500RM2U units for my rack used on ebay last year. The seller put fresh batteries in them before selling them, and they have gone from 50 minutes of runtimes...

Hi guys, I consider purchasing a rackmount UPS (SMT1500RMJ2U - same as the model in the title but for the Japanese market, e.g. 100V). Does anybody know how loud the fans of these units are when they are NOT running on battery power? APC states a value of 46db(A) on their website which would...

Hi, I just found a 2nd hand APC Smart-UPS 1000VA (SUA1000UXI) with brand new batteries, which I'm considering to use for my FreeNAS server. In the NUT compatibility list (Network UPS Tools - Hardware compatibility list) this UPS is labeled as the worst possible: But what does this mean? *...

I got a Dell UPS 2700R (J727N) in 2017 (I got it "for free" when I bought a server rack). At that time, I lived in a small apartment and did not have the fuse (16A) or space (noise-wise) to run it. It did work perfectly back then, and I played around with it for about a week before putting it in...

I’d like to start off by saying I’ve used STH as a reference for a long time, but this will be my first post. I hope someone can find this valuable, if only as something to laugh at, or as a good warning. In all honesty, I will however say that while I won’t recommend that anyone do this...

I have a couple of APC SUA2200RM2U UPSs which are due for battery replacement. It has been a few years since I shopped for batteries. I used to like Japanese brands. But many of the brands changed ownership, moved factories to China or just disappeared. So I did a quick Ebay search and there...

Over the last year or so I hoped to either build or buy a silent computer rack. During that time, I almost gave up several times because the cost and/or time involved was very substantial - whether I built (substantial time) or bought (substantial cost). Ultimately, I recently had two...

I have for sale a pair of APC UPS's SRT8KRMXLT that were purchased for a datacenter project that was abandoned. They were taken out of box but they have never even been hooked up to mains power. Some light scratches from being moved out of box but no dents. I still have the front covers in...

Hi, I have a few questions regarding getting an ups. Back story I'm looking to get my first "proper" homelab, and was looking for a smallish server rack. And I think I found one – the only thing is that the seller is also selling a 4 year old Dell J727N 2700 W UPS. I have no experience with a...

Hi all, This is my first time putting together a rack and I was wondering how to calculate how much power it will need? This rack is setup in a room where two out of three outlets are 2 pins, so I am left with plugging in the UPS directly to the wall to the single outlet. Here is the setup I...

Good Morning, I am new to this forum but it looked like the best place to be for some of my future questions. For the moment though, just this. I am building a small rack server for a race team that will travel around with us from track to track, it is just an entry server, as all it is...

Hello all, I have a small, but fairly dense virtualization and storage network that needs 24/7 uptime (some VMs I host are crucial to operation at a few local businesses), currently afforded by two consumer Cyber Power "1500VA 900W" units (CP1500PFCLCD). I can get maybe 10-15 minutes each out...

As the title states... APC 3000XL, battery extender, Share UPS, rails The UPS is 30 AMP and will NOT work with a standard outlet. I don't have a way to test if batteries are good. I'm told by the previous owner that they held a charge for 4 days before dying without anything plugged in. But...
