Securing the Chassis

This chapter describes how to secure the Cisco NCS 4016 chassis in the rack.


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 Cisco NCS 4016 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.

To bolt the rack to the floor, a floor bolt kit (also called an anchor embedment kit ) is required. For information on bolting the rack to the floor, consult a company that specializes in floor mounting kits (such as Hilti; see Hilti.com for details). Make sure that floor mounting bolts are accessible, especially if annual re-torquing of bolts is required.

Warning

 

The chassis should be mounted on a rack that is permanently affixed to the building. Statement 1049

Preparing to Mount the Chassis in a Rack

Before you mount the Cisco NCS 4016 chassis into a rack, it is critical that the installation site be prepared properly to handle the chassis weight, power requirements, cooling needs, and other requirements.

Because a fully-configured chassis weight can be up to 412 lb (187 kg), you should review the rack specifications from the manufacturer to determine whether the racks you have are appropriate to handle the weight of the chassis. For specifications on the chassis, see the Cisco Network Convergence System 4000 Series Hardware Installation Guide .


Caution

To avoid tipping the chassis and possible injury when installing it, take care to properly position the chassis in the rack when you are mounting it.

Before mounting the chassis in the rack, perform the following steps:

Installing the Mounting Brackets

This section explains how to install the top and bottom mounting brackets for the specific type of rack you are using.

  • For 2-post ANSI racks, the brackets are installed in the middle position.
  • For 4-post ANSI racks and ETSI cabinets, the brackets are installed in the front position.

Prerequisites

Make sure that you have the correct type of mounting brackets to suit your rack type. There are three different types of mounting brackets for the three types of racks (ANSI 19-inch or 23-inch or ETSI).

Required Tools and Equipment

  • Number 1 Phillips screwdriver
  • Cisco NCS 4016 installation kit (NCS4K-INST-KIT=)

Installing the Mounting Brackets

To attach the mounting brackets, simply fix each bracket onto the chassis using six screws as shown in the figure, below.

Figure 5. Attaching ANSI 23-Inch Brackets to Front (4-Post Rack) or Middle (2-Post Rack)
Figure 6. Attaching ETSI Brackets to Front

Installing the Aid Brackets

This section explains how to install the aid brackets onto the rack. The aid brackets hold the weight of the chassis while you secure it in the rack.

Prerequisites

Identify the position of the chassis inside the rack to define the aid brackets position.

Required Tools and Equipment

  • Number 1 Phillips screwdriver
  • Cisco NCS 4016 installation kit (NCS4K-INST-KIT=)

Steps

SUMMARY STEPS

  1. Attach the aid brackets to the rack below where the chassis will sit. Tighten the two screws to firmly attach the brackets to the rack.
  2. Once the chassis has been installed, remove the aid brackets. Loosen the two screws from the aid brackets and take off the rack.

DETAILED STEPS

Step 1

Attach the aid brackets to the rack below where the chassis will sit. Tighten the two screws to firmly attach the brackets to the rack.

Figure 7. Attaching Aid Brackets to the Rack

Step 2

Once the chassis has been installed, remove the aid brackets. Loosen the two screws from the aid brackets and take off the rack.

Tip

 

Keep the aid brackets in case of future chassis relocation.

What to do next

To accommodate equipment racks with different mounting hole patterns, the aid brackets have groups of screw holes on either side.

The mounting holes in the aid brackets are spaced so that one mounting hole in each hole group aligns with a corresponding hole in the equipment rack. By using the corresponding mounting hole (in the same hole group) on the opposite side of the rack, you can keep both the aid brackets leveled.


Caution

When you are installing the chassis in a rack, leave the filler cards in place to provide the chassis with enough support to keep it square during the procedure.


Caution

Because of the chassis size and weight, it is unsafe to lift the chassis without mechanical assistance.

Removing the Chassis Door

Before installing the chassis in a rack, remove the front door of the chassis to ensure that the door is not damaged in any way.

Required Tools and Equipment

• ESD-preventive wrist strap

• Number 2 Phillips screwdriver, medium and small slot-head screwdrivers
