Description
The D-Link DGS-1250-28X is a black L3 managed switch with 24 Gigabit Ethernet (10/100/1000) RJ-45 ports and 4 slots for SFP+ modules. It includes an RJ-45 console port and offers 10G support, which expands the connection options in the network. Its management is based on web-based administration, configuration of location settings via CLI and event logging in the system. Quality of service (QoS) allows traffic to be prioritised, while ARP inspection strengthens control of communications. It supports VLAN with up to 4094 virtual networks, flow control, head-of-line (HOL) blocking and storm transmission control, as well as full duplex operation. Its dimensions are 440 x 44 x 140 mm (width x height x depth) and it weighs 3.86 kg, so it integrates easily into communications cabinets.
