Cisco CRS Manual

DETAILED STEPS
Step 1
Ensure that the unistruts are installed. See the Steps, on page 4.
Step 2
Attach the rear vertical cable troughs —one right and one left—to the rear of the chassis (as shown in the figure below)
by i nserting the 10 M4x14-mm flat head screws (5 on each side) and using the screwdriver to fasten the screws to attach
the cable troughs firmly to the chassis.
We recommend that you use two people to install the troughs, one person to hold the troughs in place while the
other person inserts and tightens the screws.
