Cisco CRS Manual

Step 8
Remove the front vertical cable troughs (see the figure below)—one right and one left—from the front (SFC) of the
chassis:
a) Use the screwdriver to remove the 10 flat-head screws (5 on each side) from the cable troughs, and set them aside.
b) Slide the cable troughs upward slightly to unhook them from the guide slots; lift them away from the chassis, and
set them aside.
We recommend that you use two people to remove the troughs, one person to hold the troughs while the
other person removes the screws.
