Application Notes

1. Full-duplex operation only applies to point-to-point access (such as

when a switch is attached to a workstation, server or another switch).
When the switch is connected to a hub, both devices must operate in
half-duplex mode.

2. When a switch is connected to a hub or any kind of shared media,

remember to turn off back pressure to prevent the attached port from
being frequently partitioned due to the jamming packets.

3. For network applications that require routing (such as when

interconnecting dissimilar network types or distinct VLANs), you may
have to attach the TigerStack 100 units directly to a router or Layer 3
switch (such as the SMC6724L3).
