ANSI Rack Installation

The ONS 15454 M6 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 ONS 15454 M6 shelf as shown in

Figure 1. 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 ONS 15454 M6 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 ONS 15454 M6 shelves in a 7-foot (2133.6 mm) equipment rack.

The following figure shows the dimensions of the ONS 15454 M6 shelf on a 19-inch (482.6 mm) ANSI rack

configuration with brackets mounted in the front position.

Installing the ONS 15454 M6 Shelf

ANSI Rack Installation

Figure 1: Cisco ONS 15454 M6 Shelf Dimensions for a 19-inch ANSI Rack Configuration

Reversible Mounting Bracket

Use only the fastening hardware provided with the ONS 15454 M6 shelf to prevent loosening, deterioration,

and electromechanical corrosion of the hardware and joined material.

Caution

When mounting the ONS 15454 M6 shelf in a frame with a nonconductive coating (such as paint, lacquer,

or enamel) either use the thread-forming screws provided with the ONS 15454 M6 shipping kit, or remove

the coating from the threads to ensure electrical continuity.

Caution

The reversible mounting bracket is used to mount the shelf on a 19-inch or 23-inch (482.6 mm or 584.2 mm)

rack.

Mounting a Single Shelf

Mounting the ONS 15454 M6 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.

Installing the ONS 15454 M6 Shelf

Reversible Mounting Bracket

If the ONS 15454 M6 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 ONS 15454 M6 shelves and a fuse and alarm panel. However, unequal flange racks are limited

to six ONS 15454 M6 shelves and a fuse and alarm panel, or seven ONS 15454 M6 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 ONS 15454 M6 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 ONS 15454

M6 shelves.

ETSI Rack Installation

The ONS 15454 M6 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 ONS 15454 M6 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 ONS 15454 M6 shelves in a 7-foot (2133.6-mm) equipment

rack.

The following figure provides the dimensions of the ONS 15454 M6 shelf installed on a 600 x 600-mm (23.6

x 23.6-inch) ETSI standard equipment rack.

Installing the ONS 15454 M6 Shelf

Mounting Multiple Nodes

Figure 2: Cisco ONS 15454 M6 Shelf Dimensions for an ETSI Rack Configuration

The standard ETSI racks can hold seven ONS 15454 M6 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.

Caution

Mounting a Single Node

The ONS 15454 M6 requires 264.16 mm (10.4-inches) minimum of vertical rack space. To ensure the mounting

is secure, use two to three M6 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 ONS 15454 M6 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 ONS

15454 M6 shelf weight, see the Dimensions.

Mounting a Single Node

Mounting Multiple Nodes

Most standard (ETS 300 119) ETSI 600 x 600 x 2200 mm or 600 x 300 x 2200 mm racks can hold seven

ONS 15454 M6 shelves, and a fuse and alarm panel. In an ETSI rack, the brackets are mounted only in the

front position.

The ONS 15454 M6 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 ONS 15454

M6 shelves.

Air Deflector

An air deflector is a sheet-metal part that is mounted on the ONS 15454 M6 shelf to orient the air flow in a

specific direction.

The air deflectors can be mounted in different positions to control the air flow:

• Front to Front— Only ETSI rack

• Front to Back— For ANSI and ETSI racks

• Front to Top— Only ETSI rack

In an ANSI rack, the air deflectors are mounted only on the 23-inch rack configuration.

Air Plenum

Air plenum orients the air flow in the front-to-back direction inside the equipment to be compliant with GR-63

issue 4 requirement.

The air plenum kit has two horizontal and two vertical air plenums. The air that flows from the front top inlet

and the front bottom inlet are channelized to the right vertical plenum, inside the equipment, and then to the

exhaust air channel towards the left vertical air plenum. The air flow is deflected by 90 degrees and exited

out in the rear end.

The following figure shows the air flow inside the cabinet.

A minimum opening of 20.600 inches is required to install the vertical air plenum behind the front rails.

The ANSI 19-inch two post rack that is compatible with air plenum installation is available from Telect, with

part number 12545-301.

This equipment is intended to be grounded. Ensure that the host is connected to earth ground during

normal use. Statement 39

Warning

For nominal voltage of -60 VDC, the input voltage range is from -40 to -72 VDC.

Note

Use only the fastening hardware provided with the ONS 15454 M6 to prevent loosening, deterioration, and

electromechanical corrosion of the hardware and joined material.

Note

When installing or replacing the unit, the ground connection must always be made first and disconnected

last. Statement 1046

Warning

The air plenum is installed on a rack or a cabinet using thread-forming screws that remove any paint

or non-conductive coatings inside the hole threads, and establish a metal-to-metal contact. Also, clean

both surfaces outside the screw points that come in contact, so that they are free of paint and other

nonconductive coating. Apply an appropriate antioxidant compound to the surfaces.
