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.
