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).

Cisco ONS 15454 ETSI
When installed in an equipment rack, the ONS 15454 ETSI assembly is typically connected to a fuse and
alarm panel to provide centralized alarm connection points and distributed power for the ONS 15454 ETSI.
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 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.

Cisco ONS 15454 M2 Shelf
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, TNCS-2, TNCS-2O, 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.
