Product Overview |
|
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 temperatures are expected
and compact size is a necessity. Both copper and fiber optic versions
are available.
The EISX 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 automatically
negotiates with its link partner the data rate to be 10 Mbps or
100 Mbps and either half- or full-duplex operation. If full-duplex is selected, the PAUSE flow control method can be selected. 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 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-MDIX ports are available on the EISX9-100T
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, 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. 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.
