CAUTION
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 was 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.
Do not connect the console ports with any other device except for Serial
communication terminal.
Deviation could lead to equipment failure.
To connect a power receiving equipment supporting IEEE802.3bt or
IEEE802.3at to this Ethernet Switch, use a cable rated Cat5e or higher.
Using other cables may result in heat generation, ignition, and/or equipment failure.
When connecting 10GBASE-T (IEEE 802.3an) supported devices to this device,
use Cat6 or above cables.
If any other cables except for the aforementioned are used, malfunctions might be
caused.
