2662.0. "slot power problem" by SVCVAX::SMITT () Tue Aug 22 1995 12:21

    
    
    	Problem : I have a customer (Pratt and Whitney) who has many 
    		HUB 900's . The problem is that In slot 5 on several 
    		Hubs The customers DSRVZ-MA's lose power . The way the
    		problem is corrected is to reseat the option . This seems 
    		to be the only slot but did see slot 3 on one occasion .
    	
    		So far on one backplane I tried a new DSRVZ-MA .
    		tightend all nuts on bus bar on back and added stiffeners
    		on backplane . 	I also checked for the relay shorting out .
    		The problem still seems to exist . The temp in the cab
    		is at 39celsius 100F . The fans are turning .

	Hi - Are there any interesting messages logged on the LCD, the Error Log (menu item 5 in MAM 4.0.x), or the Event Log (menu item 8)? Once the module is reseated, how long does the hub remain in full operation? What does the DEChub 900 LCD say about how many watts of power are available? What other modules are in each hub? Is a DSRVZ-MA a 900 module or a 90 module? If the hubs have insufficient power, the hub will power down 900 series modules, starting from slot 1, until the remaining modules are within the power budget. 90 modules are not affected, however.

Hi -

Are there any interesting messages logged on the LCD,
the Error Log (menu item 5 in MAM 4.0.x), or the
Event Log (menu item 8)?

Once the module is reseated, how long does the hub
remain in full operation?

What does the DEChub 900 LCD say about how many watts
of power are available?  What other modules are in
each hub?  Is a DSRVZ-MA a 900 module or a 90 module?

If the hubs have insufficient power, the hub will
power down 900 series modules, starting from slot 1,
until the remaining modules are within the power
budget.  90 modules are not affected, however.
