6—Using the S-4000 System
REAC Cable Length Extension
If necessary, the REAC cable length can be extended by placing an Ethernet switching hub in-line to
refresh the REAC signal. Multiple switching hubs can be used (up to four total), with a maximum cable
length of 100 meters between hubs. (Total cable length with four switching hubs: 500 meters.)
See Chapter 5 for a discussion about Ethernet cables. See the Appendices for a crossover cable
wiring diagram and Ethernet switching hub requirements.
Use Cat5e straight-through cables to connect REAC devices to the ports on the switching hub. If
multiple hubs are used, use Cat5e crossover or straight-through cables to connect hub-to-hub.

Some switching hubs have ports that allow the use of either crossover or straight-through
cables—they will detect the type of cable that’s connected and adjust the signal transfer
accordingly. Consult the documentation for the switching hub to determine what type of cables
can be used.
Using an Ethernet Switching Hub with Redundant REAC Connections
If an Ethernet switching hub with at least four ports is used in-line for cable length extension, the
S-4000S and S-4000H MAIN and BACKUP REAC ports can be connected to the ports on a single hub.
The proper signal negotiation will be handled within the switching hub. (See the diagram on the
following page.)
If you connect both the MAIN and BACKUP REAC ports to a single switching hub, you are
weakening the redundancy of the system somewhat—if the switching hub fails, both the MAIN
and BACKUP connections fail along with it. Therefore, in critical installations you may want to
consider using separate switching hubs for the MAIN and BACKUP REAC device connections.
