recommended space also ensures that you have enough space available to perform
the initial installation of the chassis and its components.
Before moving the
chassis into position, make sure that you have properly prepared the site so
that there is sufficient room for installation and maintenance.
The floor plan for
the Cisco CRS 8-slot line card chassis must include enough space to install the
chassis in the equipment rack and allow sufficient airflow for the system. The
floor plan must also provide enough room to access chassis components for
maintenance (for example, to remove fan trays, power modules, cables, and air
installation, make sure that enough room exists in front of the chassis to
accommodate installation personnel and the lifting device used to hold the
chassis in the rack while it is bolted to the rack.
The following figure
shows the service area flooring in a lab from the top of the chassis.
