The EICP series of compact switching hubs from Contemporary Controls fills the need for those industrial and commercial applications requiring a small footprint and a temperature range between 0° to +60°C. Copper and fibre versions are available in this product line.
The EICP segments the Ethernet LAN into multiple collision domains. It acts as a 'bridge' between data links - creating a larger network diameter than possible with repeating hubs. Each twisted-pair port senses the capabilities of the device at the far end of its link, then automatically optimises the data rate to 10 or 100 Mbps and duplex operation to half or full. Full-duplex negotiation implements the PAUSE method of flow control. Half-duplex links use backpressure for flow control.
The switch learns port assignments by reading Ethernet frames and logs source addresses into a table that can hold over 4000 addresses. With this information, it improves throughput by restricting traffic to only those ports party to a data exchange - while other data is simultaneously exchanged on other ports. Store-and-forward operation of frames is implemented using 256 KB of built-in memory.
Only standard straight-through cables are needed to connect copper ports to NICs or another hub. Eight auto-MDI/X ports are available on the EICP9-100T for attaching local devices, or for use as an uplink port. The ninth port has a conventional MDI/X port and a MDI port that can be used as an uplink port. This allows cascading to another hub without the need of a crossover cable. In addition to one power LED, eachport has an LED showing link/activity/data rate.
The unit is shipped with a DIN-rail clip installed. If direct mounting to a sub-panel is desired, a panel mounting bracket can be installed. The EICP series can be powered from wide-range, low-voltage AC or DC power sources. Redundant power connections are provided for back-up.
