12COREBUILDER 6000 INTELLIGENT SWITCHING SOFTWARE REVISION 8.2.0
To verify that you have an LMM+ module and not an LMM module installed:
1Check that the module’s ejector tab is labeled “LMM+”
2Determine the revision of your LMM+. From the top level of the Administration Console, enter:

To upgrade your LMM or LMM+, see “Upgrading Your LMM or LMM+” on page 4.
HSI Switch Engine
You can combine the Fast Ethernet Switching Module (FESM) and FDDI Switching Module (FSM) into a multiboard high-speed interconnect (HSI) switch engine. An HSI switch engine is a combined set of FSMs or FESMs which, when inserted into the HSI bus according to specific configuration rules, operates as a single switch. Multiple FSMs and FESMs in a single HSI switch engine bridge the combined set of external ports on all modules in that switch engine. Additionally, as you add a new module to an existing HSI switch engine, the system automatically adds configuration information for the existing HSI switch engine to the new module. You must manually configure any port-specific information, however.
Ability to Administer Fast Ethernet Ports
New menus on the Administer menu allow you to administer Fast Ethernet ports on the Fast Ethernet Switching Module (FESM) and the Tri-Media Module (TMM-FE). You can now configure Fast Ethernet ports to support:
■Full-duplex operation
■Intelligent flow management (IFM)
Full-duplex operation. By default, FESM and TMM Fast Ethernet ports operate in half-duplex mode. In this mode, data flows through the port in only one direction at a time. If you change this operating mode to full-duplex, the port transmits and receives data through two separate channels.
