• A standard straight-through UTP cable (MDI to MDI-X, as shown in
F
igure 2-8) is customarily used for connection to a workstation adapter
card or transceiver.

• A crossover cable or adapter must be used for directly connecting an
MDI-X port on a hub to an MDI-X port on another device. Configuring
your 100-series hub as an MDI device will avoid the need for a
nonstandard crossover cable.
Verifying Your Installation
After you have completed all necessary installation steps for your 100-series
hubs, verify that the installation was successful by checking hub and module
LEDs, port connections, and adherence to all relevant configuration guidelines.
The verification process works best when your stack meets these criteria:
• Cable connections are in place.
• All hubs and modules are installed.
NOTE: Bay Networks recommends that you use the MDI-X/MDI button
to set the 100-series hub port 1 to MDI and use a standard RJ-45 patch
cable to connect directly to the MDI-X port on another device, rather
than using a crossover cable.
