CAUTION
Check whether the optical fiber cable connectors are contaminated with dust, etc.
This might cause the optical signal to not be transmitted normally, and cause
misoperations and malfunctions. If they are contaminated, make sure to clean
them off, then connect them to the optical fiber ports.
This Ethernet Switch is to be periodically serviced in order to maintain its
performance.
Please assign a product administrator, and be sure to implement periodic
maintenance. When doing maintenance, check the inspection chart that is
posted on our website which has the requisite items listed on it.
When using this Ethernet Switch to design systems, use it after applying
appropriate measures such as setting up redundant configurations.
Communication failures might be generated due to causes such as malfunctions or
misoperations while the Ethernet Switch is being used.
When using this Ethernet Switch for applications which require extremely high
reliability, be careful to expend all possible means to ensure safety and
reliability.
This Ethernet Switch is not designed or manufactured with the intention that it be
used for applications (in use with railways, aviation, and medical care, etc. where
the influence rate due to communication failures is extremely high in regard to
systems that directly affect systems and human lives) which require extremely high
reliability.
It is recommended that this Ethernet Switch be replaced about five years after
it has been installed.
This may vary depending upon conditions such as utilisation rates and usage
environments, but performance might decrease due to the age-related degradation,
etc. of components.
Be careful in regards to environmental restrictions whereby the Ethernet Switch
can be used.
Please isolate the business power lines and communication lines. Isolate distribution
lines and other distribution lines, and low current power lines, optical fiber cables,
metallic water conduits, and gas conduits, etc. Noise may be generated in the
communication lines which might cause communication glitches.
Do not connect the console ports with any other device except for serial
communication terminal.
Deviation could lead to equipment failure.
