DGS-9168GP-AIO_S is managed redundant ring Ethernet switch with 16×10/100/1000Base-T(X) ports and 8×100/1000Base-X SFP ports. With completely support of Ethernet Redundancy protocol, O-Ring (recovery time < 30ms over 250 units of connection) / Open-Ring / O-Chain / MRP / Fast Recovery and MSTP (RSTP/STP compatible) can protect your mission-critical applications from network interruptions or temporary malfunctions with its fast recovery technology. And support wide operating temperature from -40 °C to 70 °C. DGS-9168GP-AIO_S includes 2 sets of bypass ports that protect the network from failures and Network maintenance by ensuring network integrity during power loss. DGS-9168GP-AIO_S can also be managed centralized and convenient by Open-Vision, Except the Web-based interface, Telnet and console (CLI) configuration. Therefore, the switch is one of the most reliable choice for highly-managed and Fiber Ethernet power substation and rolling stock application.
