Do not put the Switching Hub into fire.
Deviation could lead to explosion and/or fire.
Do not insert nor drop any foreign objects such as metal or readily combustible
things into the inside through the openings, twisted pair ports, console ports,
or SFP extension slots.
Deviation could lead to fire, electrical shock, and/or equipment failure.
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 keeping connected for a long time, could lead to fire.
Connect this Switching Hub to ground.
Deviation could lead to electric shock, malfunction, and/or equipment failure.
Connect the power cord firmly to the power port.
Deviation could lead to electric fire, shock, and/or malfunction.
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.
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.
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 except for the our optional SFP module
(PN54021K/PN54023K) to the SFP extension slots.
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.
Be sure to connect the ground cable.
Otherwise this might cause electrical shocks, misoperations and malfunctions.
