troughs, close the cable covers, and secure the cables with the six Velcro straps.
Route the cables through the cable troughs in this order: Route the cables through
the front-most cable trough, then through the small cable trough, then through the
rear-most cable trough.
When securing the cables with the Velcro straps located on the front slide bar,
17.
ensure that the Velcro straps do not wrap around the bottom of the slide bar.
Otherwise, expansion and contraction of the slide bar might be hindered when the
server is extended from the rack and returned to the rack.
Ensure that the secured cables do not extend above the top or below the bottom

of the server to which they are attached.
Otherwise, the cables might snag on other equipment installed in the rack when
the server is extended from the rack or returned to the rack.
If necessary, bundle the cables with additional Velcro straps to ensure that they
19.
stay clear of other equipment.
If you need to install additional Velcro straps, wrap the straps around the cables
only, not around any of the CMA components; otherwise, expansion and
contraction of the CMA slide bars might be hindered when the server is extended
from the rack and returned to the rack.
