CAUTION
If the device is going to be mounted onto a rack, use the 2 installation brackets
(for 19-inch rack mounting) which include the 19-inch rack
mounting brackets
(for 1 rack) and the 8 screws (for the rack installation brackets and for the main
unit connections), and install the installation brackets into each of the 4
horizontal holes in the device, then securely secure it and set it up.
If it is not firmly secured, then deviation could lead to falling, injury and/or
equipment failure.
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 nor 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.
Be aware of glitches which are caused in the usage environments such as
age-related degradation, etc.
This may vary depending upon conditions such as utilization rates and usage
environments, but performance might decrease due to the age-related degradation,
etc. of components. It is recommended that this Ethernet Switch be replaced about
five years after it has been installed.
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 any other devices except for
100BASE-TX/1000BASE-T/2.5GBASE-T/5GBASE-T/10GBASE-T devices to the
twisted pair ports.
Deviation could lead to equipment failure.
Do not insert any other modules into the SFP+ expansion slots (ports 5 and 6)
except for the separately sold SFP modules (PN54022/PN54024), and the SFP+
modules (PN59021/PN59023).
Deviation could lead to equipment failure.
Check our website for the latest information on supported SFP modules.
