Mounting the Chassis
This chapter describes how to secure the chassis in the rack.
Note Unless otherwise specified, "chassis" refers to both Cisco NCS 4016 chassis and Cisco NCS 4009 chassis.
Note To install two Cisco NCS 4016 chassis in a single rack, you will need to have a minimum vertical opening
of 48 RU. If you are using the DC Power Front Connection Adapter, only one chassis will fit into the rack.

Preparing the Rack for Chassis Installation
Install the chassis into one of the following standard racks:
• ANSI 19-inch or 23-inch (2- or 4-post)
• ETSI
Note
For the ANSI 19-inch rack, the minimum front opening must be 17.72 inches (450 mm) to allow for chassis
insertion.
If you are installing a single chassis in a rack, the chassis must go in the middle or bottom portion of the rack
or follow your company chassis mounting practices.
Note At the bottom of the rack, keep 1 rack unit free to allow for removal of the bottom fan tray.
