3Com 5101M-MGT installation and operation guide Ethernet Backplane Combination Reference Chart

As shown in Table 1-1, Ethernet_3 is the best Ethernet network selection to use in a mixed protocol environment because it affects the least amount of Token Ring and FDDI network paths.

Table 1-1. Ethernet Backplane Combination Reference Chart

Ethernet Paths		Token Ring Paths	FDDI Paths
Ethernet 1 removes	Token Ring 1		FDDI 1
	Token Ring 2		FDDI 2
	Token Ring 3		FDDI 3
	Token Ring 4
	Token Ring 5
	Token Ring 6
Ethernet 2 removes	Token Ring 7		FDDI 4
	Token Ring 8		FDDI 5
	Token Ring 9		FDDI 6
	Token Ring 10
	Token Ring 11
Ethernet 3 removes	Token Ring 13		FDDI 7
	Token Ring 14		FDDI 8
