Q: How do you connect two 100Base-T Hubs together?
The connection method depends on whether the Fast Ethernet hub is a Class I or Class II hub.
- For the HP Advancestack 100Base-T Hub-8txe and the HP ProCurve Switch 100Base-T Hub 8, which are Class II hubs, plug a straight-through cable from the MDI port on one hub to the MDI-X port on the other hub.
- For the HP Advancestack 100Base-T Hub-12tx and the HP Advancestack 100Base-T Hub-12txm, which are Class I hubs, only one single repeater is allowed. These hubs, however, can be stacked to allow up to five of these hubs in a stack.
Q: How do I connect a Fast Ethernet Hub to a 10Base-T Hub?
The HP Advancestack 100Base-T Hub-8txe and the HP ProCurve Switch 100Base-T Hub 8 can only be directly connected to another Class II 100Base-T hub or to a switch. To connect them to a 10Base-T hub, either use a switch in between, or connect them to the HP ProCurve Switch 10/100 Hub 12 or HP ProCurve Switch 10/100 Hub 24 which are both Class II hubs that autosense the speed of each port to be either 10Mbps or 100Mbps.
For the HP Advancestack 100Base-T Hub-12tx and the HP Advancestack 100Base-T Hub-12txm, insert an optional HP Switch Port Module into one of the hubs. From the port on that module, you connect a Category 5 cable (or fiber-optic cable) to the 10Base-T hub.
Q: How far apart can I keep my hubs?
