C.2.5.3 Connecting Adapters with Token Ring Pinouts to Cabletron Switches

Like switches, some adapters use different pin assignments than those men- tioned before. Connecting one of these adapters to a Cabletron Switch would require the connections to be mapped as follows:

•Pin 3 to pin 1 in both directions.

•Pin 4 to pin 7 in both directions.

•Pin 5 to pin 8 in both directions.

•Pin 6 to pin 2 in both directions.

Alternative	Pin	Pin	Cabletron Switch
adapter	1	1	RX+
	2	2	RX-
TX+	3	3
RX+	4	4
RX-	5	5
TX-	6	6	TX+
	7	7
			TX-
	8	8

NOTE: The cable used in the connections shown in sections 2 and 3 above must be either a UTP-3 or UTP-5 bidirectional crossover cable, with 8-pin male RJ-45 modular connectors at each end.
