Install the ONS 15454, ONS 15454 M2 and ONS 15454 M6 shelves in compliance with your local and national electrical codes:

• United States: National Fire Protection Association (NFPA) 70; United States National Electrical Code.
• Canada: Canadian Electrical Code, Part I, CSA C22.1.
• Other countries: If local and national electrical codes, are not available, refer to IEC 364, Part 1 through Part 7.

When installed in an equipment rack, the ONS 15454 ANSI assembly is typically connected to a fuse and alarm panel to provide centralized alarm connection points and distributed power for the ONS 15454 ANSI. Fuse and alarm panels are third-party equipment and are not described in this documentation. If you are unsure about the requirements or specifications for a fuse and alarm panel, consult the user documentation for the related equipment. The front door of the ONS 15454 ANSI allows access to the shelf, fan-tray assembly, and fiber-storage area. The backplanes provide access to alarm contacts, external interface contacts, power terminals, and BNC/SMB connectors.

You can mount the ONS 15454 ANSI in a 19- or 23-inch rack (482.6 or 584.2 mm). The shelf weighs approximately 55 pounds (24.94 kg) with no cards installed.

The ONS 15454 ETSI is powered using -48 VDC power. Negative and return power terminals are connected via the MIC-A/P and the MIC-C/T/P FMECs. The ground terminal is connected via the 2-hole grounding lug.

Note

The ONS 15454 ANSI is designed to comply with Telcordia GR-1089-CORE Type 2 and Type 4. Install and operate the ONS 15454 ANSI only in environments that do not expose wiring or cabling to the outside plant. Acceptable applications include Central Office Environments (COEs), Electronic Equipment Enclosures (EEEs), Controlled Environment Vaults (CEVs), huts, and Customer Premise Environments (CPEs).

For information on hardware and software specifications for the ONS 15454 ANSI shelf, refer to the ONS 15454 Shelf Specifications.

The front door of the ONS 15454 ETSI allows access to the shelf, fan-tray assembly, and fiber-storage area. The FMEC cover at the top of the shelf allows access to power connectors, external alarms and controls, timing input and output, and craft interface terminals.

You can mount the ONS 15454 ETSI in an ETSI rack. The shelf weighs approximately 26 kg (57 pounds) with no cards installed. The shelf includes a front door and a Front Mount Electrical Connection (FMEC) cover for added security, a fan tray module for cooling, and extensive fiber-storage space.

The ONS 15454 ETSI is powered using –48 VDC power. Negative, return, and ground power terminals are connected via the MIC-A/P and the MIC-C/T/P FMECs.

For information on hardware and software specifications for the ONS 15454 ETSI shelf, refer to the ONS 15454 Shelf Specifications.

The ONS 15454 M2 is designed to comply with Telcordia GR-1089-CORE, Issue 5. The ONS 15454 M2 provides only Type 2 and Type 4 interfaces. A single ONS 15454 M2 shelf supports both ANSI and ETSI standards.

The ONS 15454 M2 shelf has 3 horizontal card slots —Slot 1, Slot 2, and Slot 3. While Slot 2 and Slot 3 house MSTP cards that provide 10 to 100 Gbps interconnections, Slot 1 accommodates the TNC, TNCE, TSC, or TSCE card (timing and control card). The ONS 15454 M2 system can be powered by AC or DC power module. The ONS 15454 M2 system contains backup flash memory that supports the database (DB) and image backup in the single mode operation. The ONS 15454 M2 shelf can be mounted on an ANSI or an ETSI rack using the mounting brackets or air deflectors. The air deflectors orient the air flow in a specific direction. The ONS 15454 M2 shelf can also be wall-mounted or desktop-mounted.

When installed in an equipment rack, the Cisco ONS 15454 M2 shelf is typically connected to a fuse panel to provide distributed power for the ONS 15454 M2. The fuse panel is a third-party equipment and is not described in this documentation. If you are unsure about the requirements or specifications for a fuse, consult the user documentation for the related equipment.

Install and operate the ONS 15454 M2 only in environments that do not expose wiring or cabling to the outside plant.

Two types of front doors can be attached to the Cisco ONS 15454 M2 shelf— the standard door and the deep door. The front door provides access to the shelf, and acts as a protective panel. The deep door provides additional space in front of the shelf to accommodate cables that do not fit inside the standard door. The deep door does not have a hinge and cannot be rotated like the standard door.

You can mount the ONS 15454 M2 on a 19-inch or 23-inch ANSI rack (482.6 or 584.2 mm), or 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. The ONS 15454 M2 shelf can also be wall mounted or desktop mounted. The shelf weighs approximately 11.02 pounds (5 kg) with no cards installed.

It is mandatory that the correct type of 19-inch ANSI rack is chosen to mount the ONS 15454 M2 shelf. The recommended shape of the rack post is shown in Figure 1. For proper airflow and cooling of the shelf, the shape of the vertical posts of the rack should be such that the airflow vents are not covered. There must be sufficient space between the shelf side walls, and the vertical walls of the rack post that are parallel to the shelf side walls, as shown in Figure 2.

The ONS 15454 M6 is designed to comply with Telcordia GR-1089-CORE, Issue 5.

The ONS 15454 M6 provides only Type 2 and Type 4 interfaces. A single ONS 15454 M6 shelf supports both ANSI and ETSI standards.

The ONS 15454 M6 shelf has 8 horizontal card slots numbered 1 to 8. While Slot 2 to Slot 7 house MSTP cards that provide 10 to 100 Gbps interconnections, Slot 1 and Slot 8 accommodate the TNC, TNCE, TSC, or TSCE cards (timing and control cards). The ONS 15454 M6 system can be powered by redundant AC or DC power modules. A single power module (AC or DC) can be used to power up the entire ONS 15454 M6 system. The ONS 15454 M6 system contains backup flash memory that supports the database (DB) and image backup in the single mode operation.

The front door of the ONS 15454 M6 shelf allows access to the shelf, fan-tray assembly, fiber-routing area, power connectors, external alarms and controls, timing input and output, and craft interface terminals. Two types of front doors can be attached to the ONS 15454 M6 shelf—the standard door and the deep door. The front door provides access to the shelf, and acts as a protective panel. The deep door provides additional space in front of the shelf to accommodate cables that do not fit inside the standard door. The deep door does not have a hinge and cannot be rotated like the standard door. The fiber or cable guide used in the ONS 15454 M6 shelf provides improved fiber management.

The ONS 15454 M6 is mounted on a 19-inch or 23-inch ANSI rack (482.6 or 584.2 mm), or 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. The rack mounting is done using the mounting brackets or air deflectors. The air deflectors orient the air flow in a specific direction.

It is mandatory that the correct type of 19-inch ANSI rack is chosen to mount the ONS 15454 M6 shelf. The recommended shape of the rack post is shown in Figure 1. For proper airflow and cooling of the shelf, the shape of the vertical posts of the rack should be such that the airflow vents are not covered. There must be sufficient space between the shelf side walls, and the vertical walls of the rack post that are parallel to the shelf side walls, as shown in Figure 2.

When installed in an equipment rack, the Cisco ONS 15454 M6 shelf is typically connected to a fuse and alarm panel to provide centralized alarm connection points and distributed power for the ONS 15454 M6. Fuse and alarm panels are third-party equipment and are not described in this documentation. If you are unsure about the requirements or specifications for a fuse and alarm panel, consult the user documentation for the related equipment.

The shelf with preinstalled air filter weighs approximately 23.55 pounds (10.680 kg) with no cards installed.

Note	Install and operate the ONS 15454 M6 only in environments that do not expose wiring or cabling to the outside plant.
