Note: The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These
terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration.
Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path
protection feature, which may be used in any topological network configuration. Cisco does not recommend
using its path protection feature in any particular topological network configuration.

Caution! Unused card slots should be filled with a detectable filler card (Cisco P/N 15454-FILLER) or a
non-detectable filler card (Cisco P/N 15454-BLANK). The filler card ensures proper airflow when operating
the ONS 15454 without the front door attached, although Cisco recommends that the front door remain
attached.

operate the ONS 15454 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).
Note: The Cisco ONS 15454 assembly is intended for use with telecommunications equipment only.
