Installing the rack rail hook-and-loop strap 
About this task 
If you do not require in-rack serviceability for your rack-mounted server, use the rack rail hook-and-loop strap, 
instead of a CMA, to manage the rear panel cables. The hook-and-loop strap can be installed on either the 
left or right rack mounting rail.
