2098.0. "valid FDDI config?" by NETRIX::"[email protected]" (Ton Dekker) Mon Mar 13 1995 05:07

Hi,

We are confused about the following FDDI/ DEChub900 config.
I think the main point is: can the A or B port of a 900 EF function as 
an M-port.
The picture looks like this:


backplane 			===================
 side:				||		 ||
				|| B	       A ||     ||B
			+----------+           +----------+
			| DECswitch|	       | PEswitch |
			|  900 EF  |	       |  900 TX  |
			+----------+           +----------+
			A ||
frontpanel		  ||
side			  ||
			  || S-port
		   +---------+
		   | DEFEA   |
		   |  SAS !! |
		   +---------+


Will this work or do we have to wait for a newer firmware release?
There is no need at all for a dual ring (is this setup)

Regards, Ton (who-is-looking-forward-to-the-ultimate-answer)

    A-S or B-S connections are fine.  But, you end up with a single
    ring and you lose the built in redundancy of the dual ring.

     Not sure what newer firmware release you're referring to?

re. 1

Bill,

the firmware question was suppost to mean only in case the S-port 
would NOT connect yet to the A or B port.
since you state that it WILL connect this question is not applicable.
