If installing to 2-Post (Telco) racks, the ReadyRails static rails (B4) must be used. Sliding rails support mounting in 4-post racks
only.

Installation in the Dell Titan or Titan-D racks
For tool-less installation in Titan or Titan-D racks, the Stab-in/Drop-in Sliding rails (B13) must be used. This rail collapses
down sufficiently to fit in the rack with mounting flanges that are spaced about 24 inches apart from front to back. The
Stab-in/Drop-in Sliding rail allows bezels of the servers and storage systems to be aligned when installed in these racks. For
tooled installation, Stab-in Static rails (B4) must be used for bezel alignment with Storage systems.
Cable management arm (CMA)
The optional cable management arm (CMA) organizes and secures the cords and cables exiting the back of the systems. It
unfolds to allow the systems 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.
● Ability to mount on either side by 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 by 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. For systems
with one power supply unit (PSU), it is recommended to mount on the side opposite to that of the power supply to allow easier
access to it and the rear drives (if applicable) for service or replacement.
