Page 12: Attaching The Token Ring Cable To Aconcentrator
To attach the TRFOT-3 to a token ring concentrator that supports Shielded Twisted Pair (STP), use the DB9 to DB9 cable supplied with the unit. If you want to attach the TRFOT-3 to a concentrator that does not have a DB9 connector, you need an adapter cable. Cabletron offers cables that adapt to RJ45 and MIC style connectors. - Page 13 Note: Perform the following steps only if the device attached to the TRFOT-3 is a Cabletron device, for example the TRFMIM-32/36/38. If you attach a non-Cabletron device to the TRFOT-3, the FO Link LED may not light, even though a good link may exist.
