Prepare and Connect Communication Cable Wiring
The option modular connector CN1 port 1 and port 2 act as a switch to allow for
flexibility in cabling topology. Users may employ a traditional star network topology
using either CN1 port 1 or CN1 port 2 on the option. Alternatively, a daisy-chained
approach may be employed by using both CN1 port 1 and CN1 port 2. The daisy-chained
approach reduces the requirements of switch ports. A ring topology is also possible. RSTP
is available to be used in a ring topology.
