Buffalo Series Black BS-GU22P BS-GU2216P

------------------------------------------------------------------------------------------------------------------ 【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. ------------------------------------------------------------------------------------------------------------------ IP routing SNMP compatible Spanning tree compatible Web setting VLAN QoS compatible Loop detection/prevention Guaranteed operating temperature 50°C Compatible with 19 inch rack IP routing SNMP compatible Spanning tree compatible Web setting VLAN QoS compatible Loop detection/prevention Guaranteed operating temperature 50°C Compatible with 19 inch rack This is a PoE switch that supports the IEEE 802.3af standard. The entire device can supply up to 120W of power. It is also possible to connect multiple wireless access points and network cameras. When the maximum power supply is exceeded, the LED will flash. You can see at a glance the upper limit on the number of devices that can supply PoE power while on site, making it easier to connect PoE devices. In order to achieve stable network operation, this product pursues high quality, including the selection of highly reliable parts based on our own quality standards, and is designed to have a long life. This product has optimized the circuit design and housing design, making it possible to operate up to 50 degrees. It can be installed in areas with high temperatures such as in the ceiling of classrooms, warehouses, and factories. As a result of our long-life design efforts, this product comes with a standard 3-year warranty, and an additional 5-year warranty can be purchased online within 30 days of purchase. If you register your product, the warranty period will be extended by 2 years, giving you a maximum of 5 years. This product achieves high quietness by adopting a fanless housing. It is also safe to install in areas where operating noise is a concern, such as hotel hallways and conference rooms. Conforms to the "VCCI ClassA" standard for preventing radio wave leakage. Achieves high shielding properties that are unlikely to adversely affect surrounding electrical appliances. This product achieves stable operation due to its design that is not easily affected by external noise. When a loop occurs, the LOOP lamp flashes red to notify you that a loop has occurred. In addition, the LED of the port where the loop occurred blinks so that you can see in which port the loop occurred. Rapid loop elimination is possible. You can easily turn the loop prevention function ON/OFF using the loop prevention switch on the front panel. How to switch on loop prevention Toggle the loop prevention switch, unplug the power cable from the outlet, and then plug it back in. This is a phenomenon in which packets continue to flow endlessly due to a network route forming a loop, causing the network to become saturated with communication packets, causing failures such as network downtime. umbrella Built-in power supply eliminates the need for an AC adapter. Not only does it keep the area around the outlet, which tends to be complicated, very clean, but it also prevents you from monopolizing the outlet.
