MISCELLANEOUS NOTES

There are three other ring interface modules available: fiber optic, 4Mbps STP only software configurable, and 4/16Mbps STP only software configurable. These additional modules have no hardware configurable options, and are therefore not illustrated. Connections between the ring interface module and the mother card are identical for every version of module.
