Aisle Spacing And Maintenance Access Floor Plan - Cisco NCS 4016 Installation Manual

Chapter 3 Site Planning Considerations
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
Note
to hold the chassis in place while you bolt it to the rack. A forklift is not recommended for this purpose.
As you plan the installation of the chassis into the equipment rack, consider the following:

Caution 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).
For chassis installation, make sure that enough room exists in front of the chassis to accommodate
Note
installation personnel and the scissor lift (or similar lifting device) used to hold the chassis in the rack
while it is bolted in.
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.)
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=).
