Contemporary Control Systems EIDX Managed Automation Switches User Manual

EIDX_M Series

A Line of Managed Ethernet Switching Hubs

INSTALLATION GUIDE

INTRODUCTION

The EIDX_M Series of managed Industrial Ethernet switches provides the user
with a sophisticated instrument with several advanced features for the
discriminating network professional. Each of the 8 models in the series operates
in extended temperatures while offering a choice of mounting, port count, media
and support.

To optimise speed and throughput, some functions are automatically negotiated:

Each twisted-pair port automatically optimises its data rate to 10 Mbps or 100
Mbps. The data rate of fibre ports is fixed at 100 Mbps.

Each port negotiates flow control — supporting the PAUSE fun ction for full­duplex links, and using the backpressure scheme for half-duplex segments.

All units offer non-blocking wire-speed operation with a maximum data rate of
148,810 frames per second for 100 Mbps Ethernet on all ports at full duplex.
Copper ports are wired MDI-X (internal crossover) for attaching NICs via straight­through cables.

All units support SNMP and offer these advanced f e a tures:

RapidRing™ high-speed redundancy (link loss recovery under 300 ms)
VLANs to limit broadcast/multicast domains and improve performance
Trunking to allow high-bandwidth redundant backbones
QoS message priority for either port-based or MAC-based priority
Programmable fault relay to indicate the loss or addition of a link
Auto-MDIX for all copper ports enabled/ disabled by software control

All units operate from low-voltage AC/DC sources — and redundant power
connections are available for backup considerations. They come with the ability
for either DIN rail or panel mounting. The front panel features LED indicators
for power and CPU status — and link status, activity and data rate of each port.
