9F426-02 Module Specific Information

•SAC (Single Attached Concentrator) Station that accesses the main ring through another concentrator and, in turn, allows the connection of more devices. SACs provide the same connections as DACs, without attaching to the dual ring.

•NAC (Null Attached Concentrator) Isolated concentrator; concentrator not connected to an FDDI ring.

While the map is updated, for example, during a ring topology change, the screen may show ??-??-??-??-??-?? to illustrate an undetermined address.

NOTE

The Ring Map display stops at the first occurrence of an undetermined address, and does not display any known information beyond this point.

To view details of a listed ring map address, use the arrow keys to highlight that address and press the Return key. The Ring Map Node Screen (9F426-02 FDDI Switch Module), Figure 4, appears.

Ring Map Screen Commands

RETURN

Closes the Ring Map Screen, and returns you to the FNB Configuration Menu.

SCROLL DOWN 1

Allows you to rotate the station addresses in the ring, one clockwise position.

SCROLL UP 1

Allows you to rotate the station addresses in the ring, one counterclockwise position.

NOTE

When the ring map contains only one station, the Scroll Up 1 and Scroll Down 1 commands do not appear.
