Cisco NCS 4016 chassis

The chassis should be mounted on a rack that is permanently affixed to the building.
Statement 1049
Warning
We recommend that you use a scissor lift or similar lifting device to position the chassis in the rack and
to hold the chassis in place while you bolt it to the rack.
A forklift is not recommended for this purpose
.
Note
As you plan the installation of the chassis into the equipment rack, consider the following:
•
Make sure that the floor mounting bolts on the equipment rack are accessible, especially if annual
retorquing of bolts is required.
•
For chassis installation, you must have access to the vertical mounting rails at each corner of the equipment
rack.
•
Consider whether the area around the rack is large enough to accommodate the scissor lift (or similar
lifting device) and installation personnel.
•
A minimum of 48 mounting screws (10-32 x 5/8 in. socket head cap screws are provided with the chassis)
are needed to secure the chassis to the rack. To secure the chassis to the rack, install twelve screws on
each of the four vertical mounting brackets.
If you plan to use mounting screws other than the ones shipped with the chassis, you can use 10-32, 10-24,
12-24, or M5 screws. (M6 and 1/4-20 screws do not fit.)
Note
•
The rack should have horizontal shelf brackets to place the chassis on. The brackets must be able to
support at least 650 lb. (294.8 kg). If the rack does not have horizontal mounting rails, a set of rails is
included in the installation kit, which is available as an option (NCS4K-INST-KIT=).
Standard rack-mounting screws are not strong enough to secure the chassis to the equipment rack. Use
only those mounting screws that are shipped with the chassis.

Aisle Spacing and Maintenance Access Floor Plan
The floor plan for the Cisco NCS 4016 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 filters).
