Planning your Dream Rack

Since I have installed and repaired many UPSes in server racks over the years, here are some of my design points if you have the opportunity to create a dream server rack.

• Have the UPS Receptacle mounted on the ceiling or the floor...  keep this important cord away from everything else
• Avoid having a UPS on rack 1 power stuff on rack 2... the wiring gets complicated.  
• Dont go crazy with this double double redundancy... most equipment has 2 power supplies.  Many people buy 2 UPSes and cross patch each power supply.   While power supplies do fail, when UPSes fail, they normally let regular power pass through.   It looks cool in the brochure, but its really unnecessary.  Use the money to buy a surge suppressor
• Buy a panel mount surge suppressor... They cost less than a UPS and honestly do a lot more for your power issues.  Get one for your main panel and your server panel, Please
• Dont mount the UPS on the top of the rack... one day you will need to change the batteries
