Manageable L3 rackmount optical switch with the possibility of connection to a stack of up to 8 switches from the TP-Link brand from the Omada series. The switch is equipped with 26x SFP+ (1/10 Gbps) and 6x SFP28 (1/10/25 Gbps ) slots for variable network expansion. All six optical ports support connection to the stack as well as classic expansion to the rest of the network. Due to the high availability, the switch allows the installation of two Hot-Swap sources (equipped with one PSM550-AC from the factory) with redundancy and 4 Hot-Swap fans for sufficient supply of fresh air from the front to the back of the switch.
