Ring Speed
The module defaults to a 16Mbps ring speed on all rings. This may be changed
though local management.
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 MMAC-Plus at the center. Consult the
MMAC-Plus Local Management Guide
for information on configuring the ports.
