Support for the Fast Ethernet Switching Module (FESM)

The Fast Ethernet Switching Module (FESM) provides high-function switching of traffic among Fast Ethernet workstations and subnetworks over the multigigabit high-speed interconnect (HSI) bus of the CoreBuilder 6000 system.

The FESM module is available in two configurations:

■Eight 100BASE-TX ports using RJ-45 connectors

These ports support connections to unshielded twisted pair (UTP) Category

5media.

■Six 100BASE-FX ports using SC connectors

These ports support connections to multimode fiber media.

The FESM automatically learns the MAC-layer addresses of workstations on attached subnetworks and forwards packets to their appropriate destinations. When used with CoreBuilder Extended Switching software, the FESM also supports routing between attached subnetworks. In addition, the FESM fully complies with the IEEE 802.1d bridging standard.

The FESM requires CoreBuilder 6000 software revision 8.2.0 or greater. This software, in turn, requires that one of the following LMM+ versions be installed in system slot 1:

■Revision 1.21 or greater of the revision 1 LMM+

■Revision 2.12 or greater of the revision 2 LMM+

CAUTION: If you attempt to run CoreBuilder system software 8.2.0 on an earlier revision of the LMM+, the system fails to reboot automatically when you turn it on.
