Do I need to buy an Eaton rack for the BladeUPS?
No. The BladeUPS will fit in any industry standard 19-inch rack. Each BladeUPS module takes up 6U of rack space based on the EIA industry standard. Each additional extended battery module (EBM) is 3U. Each “U” is equal to 1.75 inches, so each module is 10.5 inches tall.
