Rack, rails, and cable management

Key factors in selecting the proper rails include:

● Identifying the type of rack in which they will be installed The spacing between the front and rear mounting flanges of the rack

●

● The type and location of any equipment mounted in the back of the rack such as power distribution units (PDUs), and the

overall depth of the rack

Reference the Dell EMC Enterprise Systems Rail Sizing and Rack Compatibility Matrix link below for the following information:

● Specific details about rail types and their functionalities

● Rail adjustability ranges for various rack mounting flange types

● Rail depth with and without cable management accessories

● Rack types supported for various rack mounting flange types

https://i.dell.com/sites/csdocuments/Business_solutions_engineering-Docs_Documents/en/rail-rack-matrix.pdf.

Topics:

• Rails information

• Cable Management Arm

• Strain Relief Bar

Rails information

The PowerEdge XR11 and XR12 only supports sliding rails. Due to the short depth of the XR11 and XR12, new sliding rails with shorter minimum extension have been created.

NOTE: No other rails are compatible with the XR11 and XR12 system.

The sliding rails shown in below image Installing the system in Stab-in sliding rails allow the system to be fully extended out of the rack for service and are available with the optional cable management arm (CMA) and optional strain relief bar (SRB). There are 2 types of sliding rails available for the PowerEdge XR11 and XR12 as listed below:

● 2-post / 4-post rack mounting – traditional datacenter rack types with post-to-post depth range 18.5-inch – 29.5-inch [470 mm – 750 mm].

● Transit case mounting for mobility – The rugged MIL 910E performance is only certified in the Pelican DE2412-05/24/05 transit case.

The PowerEdge XR11 and XR12 sliding rails are stab-in style. A "stab-in" design means that the inner (chassis) rail members must first be attached to the sides of the system and then inserted into the outer (cabinet) members installed in the rack. 2U systems require a two-person lift.

Figure 30. Installing the system in stab-in sliding rails

42 Rack, rails, and cable management

Dell PowerEdge XR11 and XR12 sliding rails overview:

● Support for tool-less installation in 19-inch EIA-310-E compliant square or unthreaded round hole racks including all generations of Dell racks. Also supports tooled installation in threaded round hole racks.

● Supports Stab-in installation of the chassis to the rails.

● Support full extension of the system out of the rack to allow serviceability of key internal components.

● Supports for optional cable management arm (CMA) and strain relief bar (SRB).

Sliding rails in 2-post rack

The sliding rails for XR11 and XR12 provide support for 2-post racks with 19-inch EIA-310-E compliant square, round, or threaded round mounting holes. Adapter brackets and screws (included in the rail kit) are necessary to mount the XR11 and XR12 into 2-post racks either in flush-mount or center-mount positions.

NOTE: Two-post racks are not supported in the rugged environment.

Figure 32. XR12 Mounted in sliding rails in 2-post center-mount configuration

Sliding rails in 4-post rack

The sliding rails for XR11 and XR12 provide tool-less support for 4-post racks with 19-inch EIA-310-E compliant square or unthreaded round mounting holes including all generations of Dell racks when the post-to-post rack depth is between 18.5-inch – 29.5-inch [470 mm – 750 mm]. There are additional screws included in the rail kit to tightly secure the rails to the 4-post rack if desired.

Sliding rails in Pelican transit case

For transit cases, a specific type of rail has been designed. It is orderable from Dell and is compatible with the Pelican DE2412-05/24/05 transit case. Dell only certifies XR11 and XR12 compliance for MIL 901E performance in this Pelican case.

Figure 36. XR11 and XR12 Transit case rails in Pelican case frame

Cable Management Arm

The optional cable management arm (CMA) for the XR11 and XR12 organizes and secures the cords and cables exiting the back of the server and unfolds to allow the server to extend out of the rack without having to detach the cables. Some key features of the CMA include:

● Large U-shaped baskets to support dense cable loads

● Open vent pattern for optimal airflow

● Can be mounted on either side by simply swinging the spring-loaded brackets from one side to the other

● Utilizes hook-and-loop straps rather than plastic tie wraps to eliminate the risk of cable damage during cycling

● Includes a low-profile fixed tray to both support and retain the CMA in its fully closed position

● Both the CMA and the tray mount without the use of tools via simple and intuitive snap-in designs

The CMA can be mounted to either side of the sliding rails without the use of tools or the need for conversion, but it is recommended that it be mounted on the side opposite to the power supplies to allow easier access to the power supplies for service or replacement.

The PowerEdge XR11 and XR12 support up to 2 AC or DC power supplies with 1+1 redundancy, autosensing and auto-switching capability.

If two PSUs are present during POST, a comparison is made between the wattage capacities of the PSUs. In the event that the PSU wattages do not match, the larger of the two PSUs is enabled and there is also a PSU mismatch warning displayed in BIOS and iDRAC.

If a second PSU is added at run-time, in order for that particular PSU to be enabled, the wattage capacity of the first PSU must equal the second PSU. Otherwise, the PSU will be flagged as unmatched in iDRAC and the second PSU will not be enabled.

The PowerEdge XR11 and XR12 Rear Accessed chassis will only support normal airflow PSUs. Reverse airflow PSUs cannot be installed in a Rear Accessed/NAF chassis due to a specific keying mechanism on the chassis and PSU. Similarly, reverse airflow PSUs are only allowed in Front Accessed/RAF chassis. A normal airflow PSU cannot be installed in a Front Accessed/RAF chassis due to the same mechanical restrictions (keying mechanism) outlined above.
