UGS5224-RMGE, the 24-port 10/100Mbps Fast Ethernet + 2 Gigabit ports or 2 SFP Fiber Ports L2 management switch. The gigabit port also provide the fat pipe to the server or backbone connectivity for boosting the total system performance. Additional 2 optional Mini-GBIC (SFP) ports allows future expanding to alternate transmission media like optical fiber for the long-distance communication to the server, storage or other switches that providing superior performance with exceptional value.

The switch can be managed through RS-232 serial port via directly connection, or through Ethernet port using Telnet or Web-based management utility associated with SNMP agent. With SNMP agent, the network administrator can logon the switch to monitor, configure and control each port from remote site so it improves the network efficiency.

In addition, the switch features comprehensive and useful function such as QoS (Quality of Service), Spanning Tree, VLAN, Port Trunking, Bandwidth Control, Port Security, SNMP/RMON and IGMP Snooping capability via the intelligent management software utility.

UGS5224-RMGE provides 24 PoE PSE switch ports and complies with IEEE802.3af standard. Its advanced auto-sensing algorithm enable providing power devices (PD) discovery, classification, current limit, and other necessary functions. It also supports high safety with short circuit protection and power-out auto-detection to PD. It is also fully rack-mountable unit that is easy to integrate into network rack cabinet.
