Figure 185: Uninstalling the Cable Tray
Caution: Always install the top cover onto the enclosure before installing the chassis into a
rack. Not having the top cover installed may damage the alignment brackets.
Step 26 : Ensure the top cover is installed.
a. From the rear of the enclosure, align the top cover with the grooves on the top of the
chassis.
b. Ensure that there is a good catch of the top cover by the chassis and slide it in all the way.
Step 27 : Install the inner rail onto the chassis making sure they are installed on the correct side. Each inner
rail will read "R" for the right or "L" for the left embossed on the side that faces away from the
chassis. Right and Left are with reference to looking at the front of the enclosure.
a. Orient the inner rails so that the flat side is facing the enclosure and the side with the
grooves is facing away from the enclosure.
b. Align the keyholes on the inner rail to the mounting pegs on the side of the enclosure and
press the inner rail flush against the chassis. If the keyholes don't line up with the pegs, flip
the rail length-wise to see if this will align them.
