Manufacturer's product description
D-Link's new DE-1824 series of
stackable 10BASE-T hubs offer two distinguished
features: video display of statistics and diagnostic
information, and segmentation of a network from a
management station. These hubs are scalable and
manageable to fully support expansion and complexity for
departmental growth. Up to 8 hubs may be daisy-chained
together, with 7 client hubs sharing an SNMP management
agent of a master hub. The daisy-chain cable is the
inexpensive twisted-pair cable and may be stretched up
to 100 meters to permit users to place the hubs in the
same stack in different rooms. The D-Link hubs can also
be easily segmented anytime to prevent the network from
being overloaded. What makes the D-Link hubs different
from other vendors' is their vacuum fluorescent display
(VFD) that shows comprehensive system status and network
traffic statistics. In appearance, the D-Link hubs look
more like a sleek stereo/video set than a piece of
network wiring equipment. In contrast to other hubs,
which use LED lights to indicate a limited number of
status and activities, the D-Link hubs are equipped with
a large VFD screen that displays distinctively an
extensive array of information, including bandwidth
utilization, collision ratio, Runt occurrences, FCS
packets and alignment errors. To prevent performance
degradation at peak traffic times, the administrator can
separate the network into smaller, independent segments.
This operation is made easy from a management station
and involves a simple point and click of the mouse on a
stack of hub front panels' bitmap on the screen. There
is no need for the administrator to actually go to the
equipment rack and disconnect the cables that
daisy-chain the stack together. After segmenting off the
network, all connected stations remain manageable
through the same management agent residing in one master
hub; there is no need to add any extra master hubs. When
peak traffic traffic recedes, the administrator can
re-connect the previously disconnected segments, again
by pointing and clicking on the mouse. |
