RM940CC RM940 CONDUCTION COOLED 10/100TX ETHERNET HUB
The GE Fanuc EmbEdded Systems family RM940 semi-managed switches are designed to address three needs:
- State of the art Ethernet switch fabric
- Implementation in form factors appropriate for embedded and quasi-embedded applications (e.g., VMEbus, Compact PCI (CPCI) and custom)
- Economical solution for implementing Layer-2 Ethernet interconnections
GE Fanuc Embedded Systems achieves these goals by integrating advanced chip sets (for high performance switching functions) with numerous media front ends (e.g., BNC, fiber and copper). A benefit of this approach is that both hardware (e.g., media types, form factor) and software feature sets may be readily tailored to meet special needs within the context of the commercial off-the-shelf (COTS) model to which GE Fanuc Embedded Systems adheres.
1.1 Features
The RM940, RM940C, RM941, and RM942 provide high performance, configurable, 10/100Mbit Ethernet switch solutions in a VMEbus or CPCI form factor. All have identical switching and configuration capabilities. The differences are in I/O access (front/rear or fiber/copper) and environmental attributes (RM940 is conduction cooled and rated for wider temperature range). Features include:
- Eight 10/100Mbit Ethernet ports
- Each port auto-negotiating supports full-duplex or half-duplex operation (copper only)
Note: The RM942 is 100BaseFX and runs at 100Mbits only
- Level-2 switching fabric connecting ports
- Full wire speed operation on all 8 ports
- No setup or operator interaction is required to enable basic switching capabilities
- Media Access Controller (MAC) address learning forwards incoming packets only to port with destination address
- Virtual local area network (VLAN) and Quality of Service (QoS) support options
- Support options configured via non-volatile serial read-only memory (SROM) for automatic power on setup
