The Ready Rails&132;&162; static rail kit for 2U Systems, including Power Edge R720 provides tool-less support for 4-post racks with square or unthreaded round mounting holes including all generations of Dell racks. It also supports tooled mounting in 4-post threaded racks & 2-post (Telco) racks for added versatility. The static rails support a wider variety of racks than the sliding rails but do not support serviceability in the rack & are thus not compatible with the CMA. This product has been tested & validated on Dell systems. It is supported by Dell Technical Support when used with a Dell system.\n \n Notes: Screws are not included in the static rail kit due to the fact that threaded racks are offered with a variety of thread designations. Users must therefore provide their own screws when mounting the static rails in threaded or 2-post racks\n\n class="generic"> Features Rack capacity 2UCompatibility Power Edge R510\n Power Edge R515\n Power Edge R520\n Power Edge R530\n Power Edge R720\n Poweredge R720xd\n Power Edge R730XD\n Power Vault DL2000\n Power Vault DL2200\n Power Vault DL2300\n Power Vault DR4100\n Power Vault DX6112 SN\n Power Vault NX3100 Product colour Silver Technical details Rack capacity 2UCompatibility Power Edge R510\n Power Edge R515\n Power Edge R520\n Power Edge R530\n Power Edge R720\n Poweredge R720xd\n Power Edge R730XD\n Power Vault DL2000\n Power Vault DL2200\n Power Vault DL2300\n Power Vault DR4100\n Power Vault DX6112 SN\n Power Vault NX3100 Colour Product colour Silver\n\n\n\n
