The Moxa EDS-518E-4GTXSFP switch is a high-quality network switch manufactured by Moxa. This switch model offers fast and reliable Ethernet connectivity for enterprise networking and server setups. With its compact design and advanced features, it is a versatile option for businesses looking to enhance their network infrastructure with a dependable switch solution. This item appears to be brand new in box. I purchased from a company going out of business and I am unable to test.
