PowerEdge M1000e Technical Guide 14
The enclosure ships by default with a single CMC, with the option of adding a second CMC to provide
a fully redundant, active‐standby fault-tolerant solution for management access and control.
Interleaved in the center of the chassis are fans and I/O modules. This arrangement optimizes the
balance of airflow through the system, allowing lower pressure build-up in the system and resulting
in lower airflow requirements for the fans. For more information, see the Back Panel Features
section in the About Your System chapter of the Dell PowerEdge Modular Systems Hardware Owner’s
Manual on Support.Dell.com/Manuals.

4.6 Rails and Cable Management
RapidRails
TM
Static Rails for square-hole racks support the following:
 Toolless installation in 19” EIA-310-E compliant square-hole 4-post racks, including all
generations of Dell racks except for the 4200 and 2400 series
 Strain relief bar and cable enumerators for managing and securing cables
 Square-hole rack adjustment range of 712-755 mm
 Minimum rail depth of 703 mm
VersaRails™ Static Rails for square- or round-hole racks support the following:
 Tooled installation in 19” EIA-310-E compliant square or unthreaded round-hole 4-post racks
 Strain relief bar and cable enumerators for managing and securing cables
 Square-hole rack adjustment range of 706-755 mm
 Round-hole rack adjustment range of 706-755 mm
 Minimum rail depth of 703 mm
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 installation in Dell or other industry-
standard racks.
