Daisy-chaining Hubs
Normally, to make a hub-to-hub connection you need to use a crossover cable. The daisy-chain port on the 140T hub is wired MDI so you can use a straight-through cable to connect the 140T to an MDI-X port on a hub or switch. When using the daisy-chain port, follow these guidelines:
•Only two hubs (ClassII) can be daisy-chained together.
•The maximum cable length connecting the hubs can’t exceed 5 meters.
100m (max) | 5m (max) | 100m (max) |
i | | i |
205m (max)
•Use a straight-through cable to connect from the daisy-chain port on one hub to any port on the other hub (except the daisy-chain port).
•Don’t connect daisy-chain ports together with a straight-through cable.
•Never daisy-chain a 140T hub with a 100Base-T Class I device (such as the Express 200 Series Stackable Hubs).

Daisy-chain Port
Do not use Port 1 and the Daisy-chain port at the same time. Port 1 and the daisy-chain port are the same logical port, except their pinouts are different.
It is also possible to connect from a daisy-chain port on a 140T to a daisy- chain port on another 140T. However, because the daisy-chain ports are wired the same (MDI) you will need to use a crossover cable just as if you were connecting two MDI-X ports together.
