Installing the Switch 408
Sample Network Topologies
Note that because of the HP Auto-MDIX feature, all twisted-pair
connections between the switch and the MDI-X ports or MDI ports
on hubs, and the connections to the end nodes and the servers can be
through "straight-through" cables. You can also use "crossover"
cables for these connections. In either case, the Switch 408 automat-
ically adjusts to the type of cable used and to the type of device at the
other end of the connection.
The 100 Mbps connection to the server and any other 100 Mbps
connections must be through category 5 or better cable.
