H3C Layer 2 Switch 24x1GE PoE+ Ethernet Ports & 4x1GE/10GE SFP+Ports (PoE Budget 370W) (LS-1850V2-28X-HPWR-GL)
The LS-1850V2-28X-HPWR-GL is a Layer 2 Gigabit Ethernet switch designed for small and medium businesses (SMBs) with high port density and PoE+ functionality. It offers basic network management capabilities through a web interface for configuration, monitoring, and troubleshooting. The switch offers a significant number of Gigabit Ethernet ports, likely 28 x 10/100/1000 Mbps RJ45 ports, for connecting devices to the network. It includes PoE+ functionality, supporting the IEEE 802.3at standard, which delivers up to 30W of power per port, eliminating the need for separate power adapters. Other specifications include 4 additional SFP ports for connecting to fiber optic cabling for longer distances or core network switches. The switch is rack-mountable for space-saving installation in network racks and has a web interface for management. Benefits for SMBs include increased scalability, PoE+ support, and basic management features for configuration, monitoring, and troubleshooting.
