Dell 4.6 Rails and Cable Management RapidRailsTM Static Rails for Square Hole Racks:  Supports toolless installation in 19‖ EIA-310-E compliant square hole 4-post racks including all generations of Dell racks except for the 4200 & 2400 series  Has a minimum rail depth of 703 mm  Provides a square-hole rack adjustment range of 712-755 mm  Includes strain relief bar and cable enumerators for managing and securing cables VersaRailsTM Static Rails for Square or Round Hole Racks:  Supports tooled installation in 19‖ EIA-310-E compliant square or unthreaded round hole 4post racks  Has a minimum rail depth of 703 mm  Provides a square-hole rack adjustment range of 706-755 mm  Provides a round-hole rack adjustment range of 706-755 mm  Includes strain relief bar and cable enumerators for managing and securing cables One of the advantages of a modular server system is the reduction in cable management needs within a rack system. The inclusion of fabric switches, integrated KVM and system management aggregation at the CMCs provides six‐fold or better cable reduction. The following table shows a comparison of a typical reduction available when using the M1000e Modular system with integrated switches, compared to traditional ―rack and stack‖ components. The configuration in the table assumes a server with four Ethernet ports and two Fibre Channel ports. In support of the M1000e, Dell offers a modular system cable management system to ease system installation in Dell or other industry-standard racks. Table 5.
