SNMP Support - SNMP (Simple Network Management Protocol) is a protocol defined by the Internet community. The EMM acts as an agent in an SNMP managed environment responding to SNMP requests and generating SNMP traps.

Inband and Out-of-Band Download - TheEMM provides both inband and out-of-band download features. An inband download is performed via TFTP (Trivial File Transfer Protocol). The out-of-band download is performed using Xmodem software and a connection to the RS-232 serial port on the front panel of the EMM.

Telnet Support - The Telnet command enables you to log in remotely to any EMM on the network and manage it from a remote EMM. You can also manage an EMM from a workstation with Telnet support.

ONline Backplane Architecture

The 3Com unique backplane architecture provides you with the power and flexibility to create multiple Ethernet, Token Ring, FDDI networks in one ONline System Concentrator. This backplane architecture allows the following networks to run in a single ONline System Concentrator:

three separate Ethernet networks and one isolated network

seven backplane Token Ring networks and one isolated network

four FDDI networks and one isolated network

Figure 1-3 illustrates how Ethernet, Token Ring, and FDDI networks coexist on the concentrator backplane. Note in Figure 1-3 that Ethernet networks and paths correspond. That is, Ethernet_1 network is always allocated to Ethernet path 1, Ethernet_2 network is always allocated to Ethernet path 2, and Ethernet_3 network is always allocated to Ethernet path 3.
