2093.0. "Legal FDDI Config?" by ANGLIN::CLAYTON (Merlin Clayton (314)947-6763) Fri Mar 10 1995 15:02

I would like to do a sanity check of the following config. 

Assume the Gigaswitch as the FDDI main concentrator. Therefore the primary
ring connection will be to the gigaswitch.

The DH900 MS on top will be the intermediate hub, and the 900 hubs on each 
floor will be the horizontal hub.  The customer requires FDDI to every hub.

So, is the following config Valid?   ... the best approach?


			900 MS B A C K P L A N E

			|======FDDI======|
			|B		A|
		----------		----------
		| 900 MX |		| 900 EF |
		|  Conc  |		| Switch |
		----------		----------
		A|  M|M|M| 		        |B
		 |   | | |			|
	---------+   | | | 			+----------
	Primary	     | | |			 Primary
	 Ring	     | | | 			  Ring
		     | | |
		     | | |
		     | | |
		     | | |
		     | | |FDDI
		     | | +---A-900EF Sw (1)
		     | |       900TM Rptr (n)	 	(3rd fl)
		     | |       900TM Srvr (n)
		     | |
		     | |  FDDI
		     | +-----A-900EF Sw (1)
		     |         900TM Rptr (n)	 	(2nd fl)
		     |         900TM Srvr (n)
		     |
		     |	  FDDI
		     +-------A-900EF Sw (1)
		    	       900TM Rptr (n)	 	(1st fl)
			       900TM Srvr (n)


	Can the M port of the concentrator be connected to the A port
	of the 900EF switch?

	This is a dual ring on the backplanes with a tree structure 
	off the front bezel of the concentrator to the remote hubs.

Any ideas will be appreciated>
