1237.0. "Installation problem" by EEMELI::RUOTILA () Mon Feb 14 1994 05:50

    
    
    	Hi,
    
    
    	We have tried to connect DECbridge620 and DECconcentrator 500
    	together using one BN24B-30 cable, but no luck.
    
    	We connected the BN24B-cable from bridges A port to
        concentrators B port, not working. Then we tried with concentrators
    	M port to bridges A or B port, but no luck. 
    
    	DECbridge 620 is running v1.3 and the FI-modules LED looks like
    	this.
    			FI BAD     OFF
    
    			1	   OFF Not transmitting or receiving valid
    				   data
    
    			FWD1	   Blink, FDDI port in broken state
    
      
    	The looback test goes fine with port B but not with port A. OK, we
        changed the FI-module, but no luck. The FI-LEDs looks exactly same
        after we changed the module.
        The cable have been tested by electric torch.
    
    	Here comes installation data.
    
    		DECconcentrator 500    DEFCN-BD, REV A01
    				       DEFCN-MB, REV A02
    				       DEFCN-HA, REV A01
    
    		DECbridge 620	V1.3   DEFEB-LB, REV B01
    				       FI-MODULE,REV A03	
    
    	Any help would be very appreciated. What could be the next step we
        should take.
