Ethernet Workgroup Design

6-15

Ethernet

As the network will be using UTP cabling, the SEHI-22FL can be removed from
the selection field.

Since growth is expected to be minimal, the Network Designer turns to examine
the products that can be used in standalone mode. Considering the remaining
field of devices, this reduces the choices available to the SEHI-22/32 and
SEHI-24/34. Both of these devices are designed to be the base of a stack of
stackable hubs. Recall that stackable products can all function without being part
of a stack, a capability which has greatly reduced the list of Ethernet products that
are standalone repeaters only.

When comparing the port count of the SEHI-24/34, which has the highest port
count, to the total station count of the proposed network, the Network Designer
notices that the SEHI-24 alone does not meet the total required number of stations
(27). While it would be possible to purchase a second SEHI device to handle the
remaining stations and provide a jumper cable to link the two devices together,
the Network Designer can link a stackable product, the SEH-22, to the SEHI-24
