That is the same conclusion i have at the moment, the biggest problem is that i need to invent all the items that i need for the job, so im currently 3D modelling the diffrent parts so i can 3D print them, and from there on i need to test the solution.
Not that worried about the humidity, the humidity i can control even an rainy day, just an matter of controlling what i put in the room and how much, i can do that with an micro controller and some logic, you actually want more then 30%RH humidity, and below 60%RH going below 30% would make the...
As i live in Denmark, most of the year we have pretty low temperatures outside, both Apple and Google are building data centers here because of the possibility to use free cooling, besides that the power here is pretty expensive (50cent pr kWH) so using AC would just make the...
I have all my server gear and network placed in my house in an around 1.8m2 (~20sqft) room, district heating enters the same room and therefor adds more heat in the winter time but more or less no heat in the summer as we dont have the heating turned on beside heating water...
Ahh me reading to fast here :( would recomend Fluke to but thats out of the price range.
Personally i use the Fluke Linksprinter 300 for most work, it's handy and covers most work, but does not provide any load for the POE part
other than that https://www.pockethernet.com/ should be an pretty...
Thanks, i have access to J5005 NUC systems and i even think that i can get hold of an J4105 based system to, my normal EXSI environment consist of 4 older DL380G6 and G7 systems, they do the job when i do testing, but the kWH prices in Denmark are around 33cent/kWH thus leaving them on is not an...
i think the HP Elitedesk 800 G2 mini would be over the normal power budget i would like to hit.
I would really like to use more or less the same power as the RPi's (when the machine Idles) thus idle power should be around 5-6watts that would be around the same wattage as the, intel J5005 CPU.
As the years have past i been using RPi's for different small tasks, and they are doing great, but some applications like Unifi requires more and more ram and faster CPU's, therefor i was considering using an low power Intel NUC or Gigabyte Brix to consolidate all the RPi into...
Been looking around for an solution to take an E1/T1 line and convert each timeslot to an RTP stream (ITU-T G.711 PCM A-Law audio 64 kbit/s PCMA).
thus I would like to define that time sloth 2 should be RTP streamed to ip address 172.18.1.2 and timesloth 3 to 172.18.1.3 etc.
+1 for Vyedmic, the other solution is calling Huber & Suhner to get the milcat5 or 7 cables, these will do the job for sure.
Been an while since i last posted any pictures here of my setup, in the mean time i moved to an new house and had the opportunity to setup an full 42U rack, bough an old HP G10000 rack to do my build in.
it's quite messy just hooked it up fast to get internet and basic, wifi back up an running...
I think the whole idea about the 100 is to trick people into buying minimum the 200 model, it simple does not make sense to make an tester that requires internet access, 9 out of 10 times the problem is the network connection :(
I only need normal copper testing, the unit will be used primarily for home use, sadly i think you are right, about linksprinter would be the best choice.
in the 400USD i need to add around 127USD due to taxes and handling to get it to denmark :(
i was thinking about the linksprinter 100, but...
Looking for an network tester, what i basic need is the Fluke/Netscout linksprinter 300, this could be in one or more units.
the features that i would like to use:
VLAN (see them no need for .q)
cable test and fault locating.
Could this be done cheaper than the linksprinter 300?
Thanks for the link, I been doing X band RF electronics for the last 14 years, when not dealing with this I normally design network installations, for primarily military C3 systems use.
Normally we tie grounds at both ends, but we don't use normal grounds, we use data grounds, these will be...
Links are stable at 1Gbit and package drops are none on the switches (CISCO), so no problem, the reason for the CAT-4 is that the building is old, and haven't been renovated yet, whenever management gives the go it will be changed and old the tokenring cabling will be removed to :).
if you only connect the ground in one end, the shielding will act as an antenna, giving problems, you need to tie it at both ends., this is basic RF electronics.
ground loops, is only an symptom of bad grounding or bad choice of solution.
I had an problem with an cable 3 months ago where the...
Theres is no need for sheilding unless it's an 256Amp, we do normal CAT4 cables that do gigabit in the walls laying with all the electric cables :) and there's I no problem, even though that CAT4 is only 10Mbit.
I have multiple runs of Cat5e 100m doing Gigabit at customers laying next to 128Amp lines without any problems, unless you live inside the Chernobyl plant i would think you got an bad keystone connection.
