Figure 32 Blue tab on rail must be pushed in
CL5504
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.
Procedure
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.
