Multi-Ring Out Capability

Any port of the module may be conﬁgured as a ring-out port through

management software. In this conﬁguration a stand-alone passive concentrator

(such as an IBM 8228) may be added to the ring as shown in Figure 2-5. This

allows for a star-wired network with the SmartSwitch 9000 at the center. Consult

the

SmartSwitch 9000 Local Management Guide

for information on conﬁguring the

ports.
