Fast Ethernet Workgroup Design
Port Count
The first device in the stack, whether an intelligent SEHI100TX-22 or
non-intelligent SEH100TX-22, will provide connections for up to 22 Fast Ethernet
stations. For every additional 22 Fast Ethernet stations or fraction thereof, the
Network Designer must add one SEH100TX-22 to the stack.
non-intelligent SEH100TX-22, will provide connections for up to 22 Fast Ethernet
stations. For every additional 22 Fast Ethernet stations or fraction thereof, the
Network Designer must add one SEH100TX-22 to the stack.
The maximum number of ports that can be supported in this fashion is 110. In
order to support more connections, the user-configurable EPIM slots on the
SEHI100TX-22 and SEH100TX-22 will have to be used. If the EPIM slots are all
used, the Fast Ethernet stack will reach its limitation of 119 users. Any Fast
Ethernet workgroup containing more than 119 stations will require the creation of
another workgroup to support the full user count.

Design Example
A travel agency sales department is looking to replace its current Ethernet
network with a Fast Ethernet network in order to gain higher throughput and
faster access to shared resources such as the two departmental file servers and the
order entry system. The department also plans to add twenty sales
representatives to the current network in the coming fiscal quarter.
