CN-OB(M,S)
INDUSTRIAL 2-PORT OPTICAL BYPASS SWITCH
WITH 4 × LC DUPLEX CONNECTORS
This manual serves the following
ComNet Model Numbers:
CN-OBM
CN-OBS
The ComNet CN-OB(M,S) is an external Bypass switch for 100M/1G/10G fiber optic
networks. This fiber optic bypass switch protects from network failures and Network
maintenance by ensuring network integrity during power loss. This fiber optic
bypass switch includes Network ports and Monitor ports. The Network ports are
used to connect to main-network connections and provide protection mechanism
and the Monitor ports are used for down-link local networking device. When the
power is on,the mode of the Bypass switch is in Normal operation mode and the
local networking device is connected with main-network. When on the power failure
state, the Bypass switch is set to bypass mode to isolate the main-network from the
local networking device.

INSTALLATION CONSIDERATIONS
These units are supplied as Standalone/DIN Rail mounted modules.
Units should be installed in dry locations protected from extremes of
temperature and humidity.
WARNING: Unit is to be used with a Listed Class 2 power supply.
IMPORTANT SAFEGUARDS:
A) Elevated Operating Ambient
assembly, the operating ambient temperature of the rack environment
may be greater than room ambient. Therefore, consideration should be
given to installing the equipment in an environment compatible with
the maximum ambient temperature (T
B) Reduced Air Flow - Installation of the equipment in a rack should be such
that the amount of air flow required for safe operation of the equipment
is not compromised.
- If installed in a closed or multi-unit rack
) specified by the manufacturer.
