4 Port In-Band OAM/IP managed switch




  • Two copper and two fibre Fast Ethernet ports.
  • Converts between 10/100Base-TX and 100Base-FX with SFP.
  • Can also be completely controlled and monitored from a centrally located managed rack.
  • Stand-alone IP Based, Web GUI, Telnet, SNMP management.
  • Supports OAM remote loopback to assist in diagnosing network problems.


FRM220-10/100AS-2 is an IEEE 802.3ah OAM compliant two copper to two fibre Fast Ethernet solution designed to make conversion between 10/100Base-TX and 100Base-FX with SFP. With stand-alone SNMP and Web-based management, the network administrator can monitor, configure and control the activity of each IEEE 802.3ah series card and remotely connected
OAM compliant converter. By offering IEEE 802.3ah OAM in-band management, this converter can also be completely controlled and monitored from a centrally located managed rack. Based on a powerful L2 switch architecture, this converter supports bandwidth control, duplex and speed configuration, VLAN tagging, Q-in-Q, QoS, Spanning tree as well as auto laser shutdown, link fault pass through, OAM loop back and dying gasp.
