2x 10/100/1000Base-T and 2x 100/1000Base-X SFP OAM/IP GbE Managed Switch



Incredibly flexible four port OSI Layer 2 Ethernet switch and media converter with two dual-rate Ethernet fibre ports.

  • Supports local / remote IEEE 802.3ah OAM / IP In-band management.
  • Configurable as 2 converters or 4 port switch
  • Supports bandwidth control, speed configuration, VLAN tagging, Q-in-Q, QoS,  jumbo frames
  • Sophisticated management features
  • Standalone or rackmount


FRM220A-1000EAS/X is a four port OSI Layer 2 Ethernet switch and media converter with two Dual-Rate Ethernet fibre ports (100Base/1000Base-X) and two copper Ethernet ports (10/100/1000Base-T). designed to make conversion between 10/100/1000Base-T(X) and 100/1000Base-X with SFP.  With embedded SNMP and Web-based management, the network administrator can monitor, configure and control the activity of each card and remotely connected OAM compliant converter.

The Layer 2 switch technologies include tag based VLAN, port trunking, fibre redundancy, 802.1D Spanning Tree Protocol, 802.3x Flow Control and ingress/egress bandwidth control per port.  Other features include duplex and speed configuration, Q-in-Q, QoS, jumbo frames as well as auto laser shutdown, link fault pass through, OAM loop back and dying gasp.This card may also be controlled and monitored via an NMC in a managed chassis.

Management Features

1000EAS/X has its own embedded processor which can be used to configure the device for stand-alone operation. When placed in a stand-alone chassis, this device supports a text based Telnet terminal with an easy to use menu system for configuration. The embedded HTTP server provides an easy to use GUI (Graphical User Interface) with any web browser. SNMP is also supported in the stand-alone operation.

When using network management software and our proprietary MIB file specifically for the 1000EAS/X, all settings can be performed, performance monitoring realized and alarm traps received. When placed in a managed chassis, such as our FRM220-CH20 with NMC (Network Management Controller) card, the 1000EAS/X card is configured and monitored through the chassis NMC via console, Telnet, Web HTTP or SNMP.
1.    Stand-alone in CH01M 1-slot or CH02M 2-slot – Serial Terminal for initial setup
2.    Stand-alone – IP settings allow management by Telnet, Web or SNMP
3.    Rack management - When placed in NMC managed rack, all other settings can be overridden by the NMC management.

Port  Rate Limiting

The FRM220A-1000EAS/X provides per port ingress and egress rate limiting. For bandwidth settings, IRL or ingress rate limit refers to limiting any packets coming into that switch port, while ERL or egress rate limit refers to limiting packets leaving that port. When rate limiting is applied, ERL will use pause commands (802.3X) when the desired rate limit is exceeded, while any IRL setting will cause packets to be dropped when the limit is exceeded. This is an important point when doing the rate limit settings.

It is preferable to set ERL at each port for the path that requires limiting so that flow control can help connected devices cope with the limiting. If IRL is employed, a connected device which has its packets dropped without flow control, will continue to send packets at its full rate. Also, since the packets are dropped, the application layer must deal with the packet loss by timing out. First choose the granularity of 64K, 1M or 10M. Then key the ‘n’ value. In the above example, granularity has been set at 1M. The n value of 25 results in 25M rate limit. The same setting rates can be applied to the egress direction.

SFP and D/D Functions

Digital diagnostics SFP report

 Modern optical SFP transceivers support digital diagnostics monitoring (DD) functions adhering to industry-standard SFF-8472. This optional feature in SFP's, also known as digital optical monitoring (DOM), gives the user the ability to monitor real-time parameters of the SFP, such as optical output power, optical input power, temperature, etc. The FRM220-NMC management card provides access to this feature through a web interface .
