Overview
When installed in an equipment rack, the ONS 15454 assembly is typically connected to a fuse and alarm
panel to provide centralized alarm connection points and distributed power for the ONS 15454. 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 allows access to the shelf assembly, fan-tray assembly, and
cable-management area. The backplanes provide access to alarm contacts, external interface contacts, power
terminals, and BNC/SMB connectors.
You can mount the ONS 15454 in a 19- or 23-inch rack (482.6 or 584.2 mm). The shelf assembly weighs
approximately 55 pounds (24.94 kg) with no cards installed. The shelf assembly includes a front door for
added security, a fan tray module for cooling, and extensive cable-management space.
ONS 15454 optical cards have SC and LC connectors on the card faceplate. Fiber-optic cables are routed into
the front of the destination cards. Electrical cards (DS-1, DS-3, DS3XM, and EC-1) require electrical
interface assemblies (EIAs) to provide the cable connection points for the shelf assembly. In most cases,
EIAs are ordered with the ONS 15454 and come preinstalled on the backplane. See the Electrical Interface
Assemblies for more information about the EIAs.
