This is the Ubiquiti EdgeRouter 10X (ER-10X). It is new and unopened. I originally purchased it to build a home network, but I haven't had time to use it, so I am selling it. This model is not officially sold in Japan, so it was imported from overseas. I believe it can be used without any problems in Japan, but please note that you may need a conversion plug for the power adapter. It is high-performance and designed for quiet operation, making it ideal for home networks and small business environments. Key Features: 10 Gigabit RJ45 ports Manageable with EdgeOS or Ubiquiti UISP Silent fanless design Compact metal chassis 12V DC power (AC adapter included *conversion plug may be required) Supports VLAN, VPN, QoS, static/dynamic routing Details: Condition: New and unopened Model: EdgeRouter 10X (ER-10X) Manufacturer: Ubiquiti Networks Included: Original box (unopened) Notes: As it is an imported product, a conversion adapter for the AC adapter may be required for use in Japan.
