EISX9-100T
Industrial Ethernet 10/100 Mbps Miniature Switching Hub
Installation Guide
The EISX9-100T segments the Ethernet LAN into nine collision domains. It
acts as a "bridge" between data links—creating a larger network diameter
than possible with repeating hubs. Each port automatically negotiates its
data rate to 10 Mbps or 100 Mbps and controls data flow with the PAUSE
function in full-duplex or the backpressure method in half-duplex.
The switch provides preamble regeneration with symmetry and amplitude
compensation—retiming signals to eliminate jitter. Digital pre-emphasis
compensates for inherent signal strength roll-off. Link integrity is monitored,
verifying that a working adapter or hub is on the distant end of a segment.
The switch learns port assignments by reading Ethernet frames and logs
source addresses on a table which 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 is implemented and broadcast,
multicast, or unicast transmissions are received by all ports.
The switch has nine normal ports for attaching local devices. A special
uplink port (9X) allows cascading two hubs with no need of a crossover
cable. In addition to one power LED, each port has an LED which shows
link/activity/data rate.
The unit mounts on TS35 DIN-rail, can operate from a wide range of low-
voltage AC or DC power and offers redundant power connections.
Designed for Industrial Ethernet applications, the switch
complies with EMC immunity and emissions compatibility
standards for industrial environments.
