Mounting the Cisco NCS 2006 Shelf

This chapter explains how to mount the Cisco NCS 2006 shelf.

The sections are:

ANSI Rack Installation

The NCS 2006 shelf is mounted on a 19-inch (482.6-mm) or 23-inch (584.2-mm) equipment rack. Make sure that the correct type of 19-inch ANSI rack is used for mounting the NCS 2006 shelf. If the shelf is mounted in the front position, then it projects 1.7 inches (43.18 mm) from the front of the rack. If the shelf is mounted in the middle position, then it projects 5.1 inches (129.54 mm) from the front of the rack. The shelf mounts in both Electronic Industries Alliance (EIA) standard and Telcordia-standard racks. The shelf is a total of 17 inches (431.8 mm) wide with no mounting ears attached. Ring runs are not provided by Cisco and might hinder side-by-side installation of shelves where space is limited.

The NCS 2006 shelf measures 10.4 inches (264.16 mm) high, 19 or 23 inches (482.6 or 584.2 mm) wide (depending on which way the mounting ears are attached), and 11.1 inches (304.8 mm) deep. You can install up to seven NCS 2006 shelves in a 7-foot (2133.6 mm) equipment rack.

The figure below shows the dimensions of the NCS 2006 shelf on a 19-inch (482.6 mm) ANSI rack configuration with brackets mounted in the front position.

Figure 1. Cisco NCS 2006 Shelf Dimensions for a 19-inch ANSI Rack Configuration

Mounting a Single Shelf

Mounting the NCS 2006 shelf on a rack requires a minimum of 10.4-inches (265 mm) of vertical rack space. To ensure that the mounting is secure, use two to three #12-24 mounting screws for each side of the shelf. For an ANSI rack, the brackets can be mounted in the front or middle position.

If the NCS 2006 shelf is fully loaded, then two people should install it. However, it is possible for one person to install an empty shelf. The shelf should be empty for easier lifting.

Mounting Multiple Nodes

Most standard (Telcordia GR-63-CORE, 19-inch (482.6-mm) or 23-inch (584.2-mm) 7-foot (2.133-m) racks can hold seven NCS 2006 shelves and a fuse and alarm panel. However, unequal flange racks are limited to six NCS 2006 shelves and a fuse and alarm panel, or seven NCS 2006 shelves using a fuse and alarm panel from an adjacent rack. In an ANSI shelf, the brackets can be mounted in the front or middle position.

The NCS 2006 shelves can be mounted above each other without any space between the shelves. This method of mounting does not restrict the air flow because the air vents are on either sides of the NCS 2006 shelves.

ETSI Rack Installation

The NCS 2006 shelf is mounted on a 600 x 600-mm (23.6 x 23.6-inch) or 600 x 300-mm (23.6 x 11.8-inch) ETSI standard equipment rack. In an ETSI rack, the shelf can be mounted only in the front position. The shelf projects 1.7 inch (43.18 mm) from the front of the rack and is a total of 431.8 mm (17 inch) wide with no mounting ears attached. Cisco does not provide ring runs, which might hinder side-by-side installation of shelves where space is limited.

The NCS 2006 shelf measures 264.16 mm (10.4 inches) high, 535 mm (21.06 inches) wide, and 304.8 mm (11.1 inches) deep. You can install up to seven NCS 2006 shelves in a 7-foot (2133.6-mm) equipment rack.

The figure below provides the dimensions of the NCS 2006 shelf installed on a 600 x 600-mm (23.6 x 23.6-inch) ETSI standard equipment rack.

Figure 2. Cisco NCS 2006 Shelf Dimensions for an ETSI Rack Configuration

Caution

The standard ETSI racks can hold seven NCS 2006 shelves. When mounting a shelf in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack. If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.

Mounting a Single Node

The NCS 2006 requires 264.16 mm (10.4-inches) minimum of vertical rack space. To ensure the mounting is secure, use two to three mounting screws for each side of the shelf. A shelf should be mounted at the bottom of the rack if it is the only unit in the rack.

In an ETSI rack, the brackets are mounted only in the front position.

If the NCS 2006 shelf is fully loaded, then two people should install it. However, it is possible for one person to install an empty shelf. The shelf should be empty for easier lifting. For information on the NCS 2006 shelf weight, see the “A.3.14 Dimensions” section on page A-14.

Note

 
When the chassis is installed in the middle position, in an ETSI rack, the cabinet doors must be kept open (if present).

Tools/Equipment

  • # 2 Phillips Dynamometric screwdriver
  • ANSI —Six #12-24 x ¾ pan-head Phillips mounting screws
  • ETSI—Six M6 mounting screws

Security Level

None


Note
The NCS 2006 requires a minimum of six RU of vertical rack space. To ensure that the mounting is secure, use two to three M6 mounting screws on each side of the shelf. A shelf should be mounted at the bottom of the rack if it is the only unit in the rack.

Procedure

Step 1

Verify that the proper fuse and alarm panel has been installed in the top mounting space. If a fuse and alarm panel is not present, you must install one according to manufacturer instructions:

  • For a DC power supply, the fuse rating must not exceed 40A.
  • For an AC power supply, the fuse rating must not exceed 10A, 15A, or 20A. For North America, the branch circuit protection must be rated 20A. The overcurrent/short circuit protection must be in accordance with local and national electrical codes.

Step 2

Ensure that the shelf is mounted on the appropriate rack equipment:

  • 23-inches (584.2 mm) or 19-inches (482.6 mm) for racks.
  • 600 x 600-mm (23.6 x 23.6-inch) or 600 x 300-mm (23.6 x 11.8-inch) for ETSI racks.

Diagram 1 of the figure below shows the NCS 2006 shelf mounted on an rack in the middle position using 19-inch mounting brackets.

Diagram 2 of the figure below shows the NCS 2006 shelf mounted on an ETSI rack in the front position.

Step 3

Lift the shelf to the desired position in the rack. If the rack is empty, place the shelf at the bottom of the rack. The placement of the shelf is dependent on where you want to install the new equipment in the rack.

Note

 
To ensure proper cooling of the NCS 2006 shelf, make sure that the space in front of the air flow vents are free of cables, fibers, and mechanical fixtures for fiber and cable management.

Step 4

Align the screw holes on the mounting brackets with the mounting holes in the rack.

Step 5

Using the Phillips Dynamometric screwdriver, install one mounting screw in each side of the assembly. Tighten the screw to a torque value of 22 in-lb (2.5 N-m).

Step 6

When the shelf is secured to the rack, install the remaining two mounting screws on either sides.

Note

 
Use at least one set of the horizontal screw slots on the shelf to prevent slippage.

Step 7

Return to your originating procedure (NTP).

DLP-L10 Mounting the NCS 2006 Shelf on a Rack (Two People)

Purpose

Step 5

Have one person hold the shelf in place while the other person uses the Phillips Dynamometric screwdriver to install one mounting screw in each side of the assembly. Tighten the screw to a torque value of 22 in-lb (2.5 N-m).

Step 6

When the shelf is secured to the rack, install the remaining mounting screws.

Note

 
Use at least one set of the horizontal screw slots on the shelf to prevent slippage.
