------------------------------------------------------------------------------------------------------------------ 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ------------------------------------------------------------------------------------------------------------------ Standards and protocols: IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, IEEE 802.3x, IEEE 802.3af, IEEE 802.3at, IEEE 802.1q, IEEE 802.1p Interfaces: 16 PoE+ Gigabit RJ45 ports, 2 Gigabit non-PoE RJ45 ports, 2 combo Gigabit SFP slots Network media: 10BASE-T: UTP category 3, 4, 5 cable (up to 100m), EIA/TIA-568 100Ω STP (up to 100m), 100BASE-TX: UTP category 5, 5e cable (up to 100m), EIA/TIA -568 100Ω STP (maximum 100m), 1000BASE-T: UTP category 5, 5e, 6 or higher cable (maximum 100m), EIA/TIA-568 100Ω STP (maximum 100m), 1000BASE-X MMF, SMF Fan quantity: 2 Physical security lock: Yes
