WARNING
CAUTION
Do not put the Ethernet Switch into fire.
Deviation could lead to explosion and/or fire.
Do not use the Ethernet Switch in dusty environments such as on floors,
underneath floors, the backside of ceilings, or wiring panels.
Do not use the Ethernet Switch in very dusty areas such as on floors, underneath
floors, the backside of ceilings, or wiring panels. Deviation could lead to fire,
electrical shock, and/or equipment failure. It is recommended that the Ethernet
Switch be operated in
environments such as the inside of racks where it is difficult
for dust to be generated.
Use the bundled power cord (AC 100 – 240 V specifications).
Deviation could lead to electric shock, malfunction, and/or equipment failure.
Unplug the power cord in case of equipment failure.
Deviation, such as keep connecting for a long time, could lead to fire.
Be sure to connect the ground cable.
Otherwise this might cause electrical shocks, misoperations and malfunctions.
Connect the Ethernet Switch via the supplied power cord to the outlet which is
connected to the ground.
If the outlet is not connected to a ground, connect the ground cable to the ground
terminal screw.
Connect the power cord firmly to the power port.
Otherwise this might cause electrical shocks and malfunctions.
Unplug the power cord if the STATUS/ECO LED (Status/ECO mode) or FAN LED
(Fan sensor) blinks in orange (system fault).
Deviation, such as keep connecting for a long time, could lead to fire.
Handle the Ethernet Switch carefully so that fingers or hands may not be
damaged by twisted pair port, SFP extension slot, console port, or power cord
hook block.
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.
CAUTION
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
10BASE-T/100BASE-TX/1000BASE-T devices to the twisted pair ports.
Deviation could lead to equipment failure.
Do not insert any other modules into the SFP expansion slots
except for our
optional SFP modules (PN54022/PN54024).
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 IEEE802.3at to this
Ethernet Switch, use a cable rated Cat5e or higher.
Using other cables may result in heat generation, ignition, and/or equipment failure.
It is strongly recommended that a lightning arrester (SPD) be installed on the
twisted pair port side and the power supply side of this Ethernet Switch.
Malfunctions might be caused due to overcurrent and overvoltage due to the
effects of lightning strikes.
