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.
