14. Basic Instructions for the Use of This Product
（1） Handle the Switching Hub carefully so that fingers or hands may not be damaged by twisted pair port, SFP extension slot,
console port, or power cord hook block.
（2） 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.
（3） Do not insert any other modules except for the our optional SFP module (PN54021K/PN54023K) to the SFP extension slots.
（4） Unplug the power plug when there is a malfunction.
Deviation could lead to fire if the power is allowed to be supplied for extended periods of time.
（5） Be sure to connect the ground cable.
Otherwise this might cause electrical shocks, misoperations and malfunctions.
Connect the Switching Hub 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.
（6） Use the bundled power cord (AC 100 – 240 V specifications).
Deviation could lead to electric shock, malfunction, and/or equipment failure.
（7） Unplug the power cord in case of equipment failure.
Deviation, such as keeping connected for a long time, could lead to fire.
（8） Connect this Switching Hub to ground.
Deviation could lead to electric shock, malfunction, and/or equipment failure.
（9） Connect the power cord firmly to the power port.
Deviation could lead to electric fire, shock, and/or malfunction.
（10） Unplug the power cord if the STATUS LED blinks in orange (system fault).
Deviation, such as keeping connected for a long time, could lead to fire.
（11） This Switching Hub is to be periodically serviced in order to maintain its performance.
Please choose a product administrator, and have them 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.
（12） When using this Switching Hub to design systems, use it after applying appropriate measures such as setting up redundant
configurations.
Communications failures might be generated due to causes such as malfunctions or misoperations while the Switching Hub is
being used.
（13） When using this Switching Hub for applications which require extremely high reliability, be careful to expend all possible means
to ensure safety and reliability.
This Switching Hub was not designed nor manufactured with the intention that it be used for applications (in use with railways,
aviation, and medical care, etc. whereas the influence rate due to communications failures is extremely high in regard to
systems that directly affect systems and human lives) which require extremely high reliability.
（14） It is strongly recommended that a lightning arrester (SPD) be installed on the twisted pair port side and the power supply side
of this Switching Hub.
Malfunctions might be caused due to overcurrent and overvoltage due to the effects of lightning strikes.
（15） It is recommended that this Switching Hub 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.
（16） Be careful in regards to environmental restrictions whereby the Switching Hub can be used.
Please isolate the business power lines and communications 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
communications lines which might cause communications glitches.
