segments ethernet_4, ethernet_5 and ethernet_6 on the Enhanced TriChannel and ethernet_7 and ethernet_8 on the ShuntBus.

∙Method 2:

This method also uses 14 pins on the backplane to set up an Ethernet segment. In this method, each module attached to that Ethernet segment will use digital collision detection identical to that used in method 1. This means that the modules will send their slot-id in parallel over the backplane. However, to allow the management module to collect statistics about these modules, they send the slot-id and port-id in serial over a single pin on the backplane.

This method is used by the 8260 modules when connected to ethernet_1, ethernet_2, and ethernet_3 segments on the Enhanced TriChannel.

Method 2 is compatible with method 1. That is, modules using method 1 and 2 can be assigned to the same Ethernet LAN segment. Therefore, you may set up ethernet_1, thru ethernet_3 to consist of a mixture of the 8250 and/or 8260 Ethernet modules.

∙Method 3:

This method uses only four pins on the backplane to set up an Ethernet segment. In this method, each module will send its slot-id and port-id in serial over a single pin on the backplane. This information allows the management module to collect statistics about the modules and ports.

For collision detection, the modules using this method rely on an analog collision detection as described in 2.2.2, ªAnalog Collision Detectionº on page 19.

This method is used by the 8260 modules when connected to ethernet_4, ethernet_5, and ethernet_6 segments on the Enhanced TriChannel as well as ethernet_7 and ethernet_8 segments on the ShuntBus.

This method is not compatible with methods 1 and 2. Therefore, ethernet_4 thru ethernet_8 segments can consist of 8260 Ethernet modules only.

Table 2 gives a breakdown of the pins which are used by 8250 and 8260 Ethernet modules when using the above methods.
