Blue Tab On Rail Must Be Pushed In - Dell DD9500 Manual

Installing the 1U cable management tray
The underneath configuration uses the 1U space beneath the shelf. Install the cable management tray before you install the main
chassis.
Prerequisites
● Ensure that you have determined the correct cable lengths, cable loops, and pigtail lengths. Consult the application guide for
the product you are installing to help determine cable lengths.
● Ensure that the blue tab on the shelf rail (directly above where the 1U Cable Management Tray rails will be installed) is
pressed in.

About this task
NOTE: This procedure describes the installation of the 1U cable management tray into a standard Dell EMC rack. For third-
party racks, use the additional hardware that comes with the 1U cable management arm to install the rails as necessary.
The rails come preassembled with adapters that fit into standard round mounting holes. If the rack has a different configuration,
use the adapters in the hardware kit that come with the tray to mount the rails.
Steps
1. Identify the left and right rails. Orient the rails so that the UP arrow is pointed up and the end of the rails that are labeled
FRONT is at the front of the rack.
