●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/ECO LED (Status/ECO mode),blinks in orange (system fault).Deviation, such as keeping connected for a long time, could lead tofire.●Handle the Switching Hub carefully so that fingers or hands may not bedamaged by twisted pair port, console port, or power cord hook block.●To connect a power receiving equipment supporting IEEE802.3af tothis Switching Hub, use a cable rated Cat5e or higher.Using other cables may result in heat generation, ignition, and/orequipment failure.Important Notice for Measures against FailuresCaused by Lightning Strikes● When connecting devices (especially outdoor devices) prone to lightningstrikes, such as network cameras or wireless access points, to a twisted pairport of this Switching Hub, overcurrent and/or overvoltage caused by light-ning may affect this Switching Hub through a twisted pair cable, causingequipment failure. When connecting such devices, we strongly recommendinstalling a lightning arrester (SPD; Surge Protective Device) at the twistedpair port side of the Switching Hub.● Overcurrent and/or overvoltage caused by lightning may affect thisSwitching Hub through a power source connected to the power port and/ora grounding line, causing equipment failure. When there is a possibility ofovercurrent/overvoltage from lightning affecting this Switching Hub from apower source and/or a grounding line, we strongly recommend installing alightning arrester (SPD; Surge Protective Device) at the power port side ofthe Switching Hub.● In case this Switching Hub fails due to lightning strikes, repair charges willapply even during the warranty period.5
