The EISX series of compact switching hubs answers the call for those industrial and commercial applications requiring a small footprint and extended temperature range from -40° to +75°C. This series is ideal for situations where outdoor temperatues are expected and compact size is a necessity. Both copper and fiber optic versions are available.
The EISX segments the Ethernet LAN into nine collision domains. It acts as a bridge between data linkscreating a larger network diameter than possible with repeating hubs. Each port automatically negotiates with its link partner the data rate to be 10 Mbps or 100 Mbps and either half- or fullduplex operation. 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 which can hold over 4,000 addresses. With this information, it improves throughput by restricting traffic to only those ports party to a data exchangewhile 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 NIMs or another hub. Nine normal (MDI-X) ports are available on the EISX9-100T for attaching local devices, but the ninth port also offers an uplink (MDI) jack to be used for cascading to another hub without the need of a crossover cable. In addition to one power LED, each port has an LED showing Link/Activity/Data Rate by color: Green for 100 Mbps and Yellow for 10 Mbps. Flashing indicates port activity.
The unit is shipped with a DIN-rail clip installed. If direct mounting to a sub-panel is desired, an optional panel mounting bracket, shipped with the product, can be installed after removing the DIN-rail clip. The EISX can be powered from either wide-range, low voltage AC or DC power sources. Redundant power connections are provided to accommodate back-up power schemes.
This product is available in three models. The EISX9-100T offers nine twisted-pair ports. The EISX9-100T/FT has eight twisted-pair ports and one multimode (1300 nm) port with ST connectors. The EISX9-100T/FC is identical except it uses SC connectors.
