2.2 Ethernet Segments on the Backplane

The 8260 allows you to set up a maximum of 6 Ethernet (ethernet_1 thru 6) segments on the Enhanced TriChannel and two Ethernet segments (ethernet_7 and 8) on the ShuntBus. ethernet_1 thru 3 can consist of 8250 and/or 8260 Ethernet modules, whereas ethernet_4 thru 8 can consist of 8260 Ethernet modules only.

Each Ethernet segment on the backplane uses a number of pins on the backplane which is referred to as an Ethernet Path in this document. There are

8Ethernet paths (ethernet_path_1 thru 8) on and 8260. ethernet_path_1 thru 6 are on the Enhanced TriChannel whereas ethernet_path_7 and 8 are on the ShuntBus.

Ethernet_path_1 thru 3 use 14 pins each to set up an Ethernet segment while ethernet_path_4 thru 8 use 4 pins each.

The Ethernet segments on the Enhanced TriChannel use the same pins on the backplane as are used by the token-ring and/or FDDI segments. Therefore, simultaneous configuration of other types of networks (such as FDDI and/or token-ring) on your hub′s Enhanced TriChannel will impact the number of Ethernet networks available for use. However, the two Ethernet segments on the ShuntBus have dedicated pins on the backplane and will not be impacted by the configuration of other segment types (that is, token-ring and/or FDDI) on the ShuntBus.

Each Ethernet segment on the 8260 utilizes one of the Ethernet paths on the backplane regardless of the number of Ethernet modules which constitute that segment. You can choose the Ethernet network (hence the Ethernet path used by your module) using the following management command:
