    NOT NECESSARY, but I have it... - I also have, available, a 1U Xeon X3210 server with 8GB of RAM and 2 160GB SATA drives in RAID1 as a "temporary" server if the client has a server go down and needs something up ASAP. I have them sign off that I am NOT responsible for any inadequacies in performance or functionality, it is MY equipment, I will support it 8AM to 9PM for 2 weeks, and at the end of those two weeks, I am taking it back. It is their responsibility to procure a replacement for their down server, and they are responsible for the PHYSICAL well being of my server.
    
    
    
    S/A

So long as you don't use any flimsy 2-prong lamp extensions anywhere, you will be in good shape. Use a quality 12 gauge three-prong extension cord. I'd suggest you put a 15A power strip inside the tent. Zip-tie it to one of the vertical poles so it's up off the floor and unlikely to get wet when watering.

Additionally, if you would like to easily check the receptacle you are using for proper polarity/grounding/safety, you can test it with one of these tester devices.
