UPS help
I am looking for a UPS to put in my cabinet
I have 2x servers that use 400w each
I have one Cisco Nexus 3048 switch
I have a juniper router as well.
I do not know how much power the switch and router use but I need a UPS system that can work for them and keep them online in case of a power outage.

How long do you expect it to run for after the power gets cut?
A UPS isn't really meant to run continuously for extended periods of time, so keep that in mind.
Our last outage at the office lasted 1 hour and 30 minutes so something around that time an hour is good for me.
In that case, you are going to need a generator along with UPS to keep power on while a generator starts.
How long do UPS systems work I was looking on amazon at https://www.amazon.com/dp/B0016P7HJA/ref=twister_B00VNI39TW?_encoding=UTF8&th=1
Since it's an office, it would probably be better and more reliable to get a small UPS that's cheap and get a good generator. A UPS that will be good enough for multiple servers/switches will probably be like 4U and cost a few grand. I don't have experience with it though since I just have a few tiny home UPS, just my opinion.
You need to do the math since we don't know all the details.
Unless you get a giant UPS which would be simply overkill and cost too much, no UPS is gonna last one and half hour.
Also UPS is basically batteries. They don't last long. I mean the batteries will need to be replaced every some years.
Thank you guys.
OR you can create Frankenstein like this:
Really helps sometimes. Cheaper than generator.

Invest in a natural gas generator if your area has the appropriate gas lines. Pair it with a couple small of UPS and you should be good.
First step is probably to measure the actual power draw - guessing 400W is the PSU rating.
As a guide, we have some APC Back-UPS BX 1400VA's in our office. 1 UPS : 1 PC and 2 monitors. Depending on the spec of the PC, they get roughly 1-2 hours.
A few pointers:
- It's worth investing in more efficient PSUs if you're going to rely on your own UPS
- Some cheaper UPSs (including ours) can't cope with very low loads so you may end up needing to feed everything from one UPS
- UPS capacity isn't determined entirely by the VA rating - some are more efficient than others
And a great way on getting your place burned down. And your insurance company dropping you as a client.
Who said that they’re going to be able to see that?
IMO, if power outage occurs frequently (1-2 times a week) and took longer than 15 minutes everytime, then it's better to use backup generator. UPS is designed to provide short-term power when the main input source fails.
He got a fuse on one of the battery cables, so, generally it should be fine.
You obviously don't have any practical experience. Nice try though.
Rather then buying one giant UPS get three or four of medium rated UPSs and match them with computers and network equipments individualy.
