Mounting the Cisco NCS 2015 Shelf

This chapter describes how to mount the Cisco NCS 2015 shelf.

The sections are:

ANSI Rack Installation

The NCS 2015 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 2015 shelf. When the shelf is mounted in the middle position, it projects 4.5 inches (114.3 mm) from the front of the ANSI rack and 4.0 inches (101.6 mm) from the front of the ETSI rack. The shelf mounts in both Electronic Industries Alliance (EIA) standard and Telcordia-standard racks. The shelf is a total of 17.5 inches (431.8 mm) wide with no mounting ears attached.

The NCS 2015 shelf measures 24.4 inches (619.76 mm) high, 17.5 inches (444.5 mm) wide, and 11.7 inches (297.18 mm) deep. You can install up to three NCS 2015 shelves in a 7-foot (2133.6 mm) equipment rack.

The following figure shows the dimensions of the NCS 2015 DC shelf on a 19-inch (482.6 mm) ANSI rack configuration with brackets mounted in the middle position.

The following figure shows the dimensions of the NCS 2015 AC shelf on a 19-inch (482.6 mm) ANSI rack configuration with brackets mounted in the middle position.

Figure 2. Cisco NCS 2015 AC Shelf Dimensions for a 19-inch ANSI Rack Configuration

Mounting a Single Shelf

Mounting the NCS 2015 shelf on a rack requires a minimum of 24.4 inches (619.76 mm) of vertical rack space. To ensure that the mounting is secure, use eight mounting screws for each side of the shelf. For an ANSI rack, the brackets can be mounted in the middle position.

If the NCS 2015 shelf is fully loaded, then two people should install it. For ease of lifting, it is recommended that the shelf be empty.

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 three NCS 2015 shelves and a fuse and alarm panel. In an ANSI rack, the brackets can be mounted in the middle position.

The NCS 2015 shelves can be mounted above each other without any space between the shelves.

ETSI Rack Installation

The NCS 2015 shelf can be mounted on a 600 x 300-mm (23.6 x 11.8-inch) or 600 x 600-mm (23.6 x 23.6-inch) ETSI standard equipment rack. In an ETSI rack, the shelf can be mounted in the middle position. The shelf projects 4.0 inches (101.6 mm) from the front of the rack and is a total of 444.5 mm (17.5 inch) wide with no mounting ears attached.

The NCS 2015 shelf measures 24.44 inches (620.776 mm) high, 17.67 inches (448.81 mm) wide, and 11.10 inches (281.94 mm) deep. You can install up to three NCS 2015 shelves in a 7-foot (2133.6 mm) equipment rack.

The following figure provides the dimensions of the NCS 2015 shelf installed on a 600 x 300-mm (23.6 x 11.8-inch) or 600 x 600-mm (23.6 x 23.6-inch) ETSI standard equipment rack.

Caution

The standard ETSI racks can hold three NCS 2015 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.

Important Notes for ETSI Rack Installation

  • The NCS 2015 shelf can only be installed in an ETSI 300 mm deep open rack.

  • If an ETSI 600 mm deep closed cabinet is used, it must have proper thermal management to dissipate the total heat load from the equipment.

  • A minimum of six inches (152.5 mm) of clearance must be maintained for the air exhaust.

  • The exhaust side of the NCS 2015 shelf must not be exposed to the exhaust of any other equipment in a back to back installation.

Mounting a Single Shelf

The NCS 2015 requires 24.4 inches (619.76 mm) minimum of vertical rack space. To ensure the mounting is secure, use eight mounting screws for each side of the shelf. If a shelf is the only unit in the rack, it should be mounted at the bottom of the rack.

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

While it is possible for one person to install an empty NCS 2015 shelf, if the NCS 2015 shelf is fully loaded, then two people should install it. For ease of lifting, it is recommended that the shelf be empty. For information on the NCS 2015 shelf weight, see the NCS 2015 Shelf Specifications.

Mounting Multiple Shelves

Most standard 600 x 300 x 2200 mm racks can hold three NCS 2015 shelves, and a fuse and alarm panel. In an ETSI rack, the brackets are mounted only in the middle position.

The NCS 2015 shelves can be mounted above each other without any space between the shelves.

Note
The NCS 2015 requires a minimum of 24.4 inches (619.76 mm) high vertical rack space. To ensure that the mounting is secure, use eight 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 60 A.
  • For an AC power supply, the fuse rating must not exceed 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 ANSI racks.
  • 600 x 300-mm (23.6 x 11.8-inch) for ETSI racks.

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 depends on where you want to install the new equipment in the rack.

Note

 
To ensure proper cooling of the NCS 2015 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 mounting screws.

Step 7
