Prerequisites
Before installing the Cisco NCS 4206, it is important to prepare for the installation by:
• Preparing the site (site planning) and reviewing the installation plans or method of procedures (MOP)
• Unpacking and inspecting the Cisco NCS 4206
• Gathering the tools and test equipment required to properly install the Cisco NCS 4206
For more instructions on how to prepare for the installation of the Cisco NCS 4206, see Preparing for
Installation.
Installing the Chassis in a Rack
The following sections describe how to install the Cisco NCS 4206 in a rack.
Installing the Chassis Brackets
The chassis is shipped with mounting brackets that can be installed on the front or rear of the chassis. To
install the brackets on the front of the chassis, perform these steps:

Step 1 Remove the rack-mount brackets from the accessory kit and position them beside the chassis.

Figure 2: Attaching Mounting Brackets for a 23-inch EIA Rack
Step 2 Position one of the brackets against the chassis side, and align the screw holes.
Step 3 Secure the bracket to the chassis with the screws removed when performing Step 1. The recommended maximum torque
is 28 in.-lb (3.16 N-m).
Step 4 Repeat Step 2 and Step 3 for the other bracket.

Installing the Chassis in the Rack
The procedures in this section apply to both horizontal and vertical mounting of the in a rack.
To install the chassis in the equipment rack, perform these steps:
Step 1 Position the chassis in the rack as follows:
• If the front of the chassis (front panel) is at the front of the rack, insert the rear of the chassis between the mounting
posts.
• If the rear of the chassis is at the front of the rack, insert the front of the chassis between the mounting posts.
Step 2 Guide the chassis carefully into the plenum assembly. See the figure below.

Step 3 Position the door onto the chassis and slide it into the rack. Secure the screws with a torque of n.-lb (N-m). See the figure
below.

Step 4 Align the mounting holes in the bracket (and optional cable guide) with the mounting holes in the equipment rack.
Do not use interface module and power supply ejector handles to lift the chassis; using the handles to lift the
chassis can deform or damage the handles.
Caution

Step 5 Install the 8 or 12 (4 or 6 per side) 12-24 x 3/4-inch or 10-32 x 3/4-inch screws through the holes in the bracket and into
the threaded holes in the equipment rack posts.
Step 6 Use a tape measure and level to verify that the chassis is installed straight and level.
Installing the Chassis with Plenum in Rack
Step 1 Position the air baffle and the side plate to the plenum. See figure below.

Step 3 Repeat Step-1 and Step-2 to complete the plenum assembly on the other side of the plenum base.
Step 4 Position the air filter (A903-F2B-AIR-F) assembly on the plenum deflector. Secure the front cover using a recommended
torque of 11.5 in.-lb (1.3 N-m). See figure below.

The filter is applicable when fan A903-FAN-H is used.
Note
Step 5 Using a crimping tool (as specified by the ground lug manufacturer), crimp the ground lug to the ground wire and connect
the other end of the ground wire to a suitable grounding point at your site. See figure below.

Step 6 Position the plenum assembly to the rack and secure the cable brackets to the rack using a torque of 11.5 in.-lb (1.3 N-m).
See figure below.
Installing the Chassis in the Air Plenum
Ensure that the chassis is not installed in the air plenum while mounting it on the rack.
Note
For instructions on mounting the plenum on the rack:
Step 1 Position the chassis so that the rear of the chassis is at the front of the plenum.
Step 2 Slide the chassis into the plenum so that the front of the chassis is in flush with the mounting rails and brackets. See the
figure below.

Installing the Chassis Ground Connection
Before you connect the power or turn on the power to the Cisco NCS 4206, you must provide an adequate
chassis ground (earth) connection to your chassis.
This section describes how to ground the Cisco NCS 4206 chassis on a rack. The chassis provides two locations
for attaching a 2-hole grounding lug according to the rack-mounting brackets you use to install the chassis.
The Cisco NCS 4206 supports the following rack-mounting types:
• EIA 23-inch rack—Attach the grounding lug to the rack, as shown in the figure below
