– Broadcast and Unknown Server (BUS): A BUS handles broadcast
data sent by a LAN emulation client, all multicast data, and data sent
by a LAN emulation client before the ATM address has been resolved.
Figure 7–1 shows an ATM network with two emulated LANs. Hosts A and B
are LECs on ELAN1. Hosts C, D, and E are LECs on ELAN2. The LECS, the
LES, and the BUS are server functions resident on the ATM switch (even
though they are shown separately).

Use LAN emulation over ATM in a TruCluster Server cluster for client
system access (Memory Channel is the cluster interconnect).
7.2 Installing ATM Adapters
_____________________ Warning _____________________
Some fiber optic equipment can emit laser light that can injure
your eyes. Never look into an optical fiber or connector port.
Always assume the cable is connected to a light source.
______________________ Note _______________________
Do not touch the ends of the fiber optics cable. The oils from your
skin can cause an optical power loss.
