comment How many power circuits do I have in a rack?
I should have said 2x30A 110V. I think that's what we used to have. Don't forget room for a switch (if needed) and out of band tools. The last thing you want is a tripped circuit breaker. Also if you do run near peak, be sure to have your PDU enforce staggered power ups. Nearly any system can cause an amp spike on power-up.

Please see serverfault.com/help/how-to-ask. Post your current configurations, state your goals and specific error your are receiving. What results do you get now? Unlike some sites, SF is geared to professional conversations about system administration not a how-to or tutorial discussion group.

comment How many power circuits do I have in a rack?
Most colo facilities will permit no more than 2x20A of power in one rack. Contact your specific colo provider for details. City fire ordinances may limit the power as well. For your systems, I would ask the manufacturer what is the expected amp draw and peak load. You will want to provision power such that you have some overhead for switches, out of band management tools etc. Note that most providers want you to stay within 80% of your peak usage so not to trip circuit breakers.

comment Nginx 502 Bad Gateway - 111: Connection refused, port not being listened to
@ADM I think that error only happens if you try to spin up another pool on the same port. This would need to be verified but I don't think that error occurs if you have two pools with the same name but different ports.

Man pages are your friend. ipset.netfilter.org/iptables.man.html see the delete chain rule.

Your iptables -N rule is creating a new chain. Chains are processed and then passed back into the main rules. So in this case your NRPE rule passes that traffic into the NRPE chain, which does not have an accept rule. By default it will drop traffic.

On the client side (the server you are telnetting from) post the results of route -n. You could have a routing table issue. If you stop iptables on the destination server, can you connect? Also note with NRPE you need to configuration authentication but that should not stop you from connecting to the port.
