1188.0. "DECbridge900 fails diags." by BIGUN::WULFF () Wed Jul 06 1994 09:05

    Hi,
    
    I have some weird problems that I cannot understand. Below is a error
    log dump of the DECbridge900 that may explain these problems.
    
    I updated a DECbridge900MX and the DEChub900 with the latest firmware
    and updated Hubwatch to V3.
    
    I then proceded to have fun by creating LANs (ethernet and fddi) and
    switched the DECbridge900MX bridge ports including the FDDI (both port
    A and B) to the backplane channels channels.
    
    I don't remember removing the DECbridge900 from the backplane without
    power but is possible.
    
    What I discovered was that sometime later was that the DECbridge900
    would fail its diagnostics whenever power was removed from the hub or
    if the bridge was removed and reinserted immediately.
    
    	Diagnostic failure would be,
    	
    	. Power light on.
    	. Fans flat out.
    	. No 1 left light flashing amber
    	. PHY port A and B flashing.
    
    Hubwatch LAN interconnect displays unknown module with FDDI links.
    Remove DECbridge900 and refresh Hubwatch and LAN interconnect then
    displays empty slot with FDDI links.
    
    If I don't put the module immediately back and leave it out for 10-15
    minutes then insert it will pass self test the module is then known to
    Hubwatch and the FDDI links will disappear.
    
    I have included the console information on the DEChub and DECbridge900.
    The error log on the DECbridge has errors and may explain these
    problems.

1188.1Need more info.....NACAD2::BATTERSBYWed Jul 06 1994 11:097
    Hi Ole. We need some additional information.
    
    1. When the failure occurs, what is the Module_OK LED doing?
    2. When the failure occurs, what color are the flashing PHY Port LEDs?
    3. Can the problem be re-created?

    Bob,

>    1. When the failure occurs, what is the Module_OK LED doing?
	
	The OK light is not on.

>    2. When the failure occurs, what color are the flashing PHY Port LEDs?

	Green.

>    3. Can the problem be re-created?

	Yes, if the following is true.

	It almost appears to be heat sensitive. All I need to do is run the 	
	module (DECbridge900) for some time remove and immediately install it 	
	back in the hub and it will fail. Leave it out of the hub for some time 
	and then install it back and it will pass diags. I have reset all 	
	modules back to factory settings and reloaded the firmware. 

	When the module passses diags I have confirmed that all the front panel 
	ports work including the FDDI port. I can switch the ports between the 	
	backplane and the front with hubwatch. I have not verified that the 	
	FDDI works on the backplane but I have verified that port 2 works ok.

	No, if the following is true. 
	
	I have not used another hub and another decbridge and followed the same 
	sequence. I am not game to as this a customer installation.

What does the error log show. Are the CRC errors some thing to be concerned
about?

Thanks,
1188.3Heat sensitive?BIGUN::WULFFWed Jul 06 1994 22:0010
I did some more testing which suggests that the module is heat sensitive.

I tried again this morning and this is what I found.

Remove power from the DECbridge900MX for a few seconds the bridge fails diags.

Remove the module from the hub for 20 minutes and reinstall module and it then
passes.

Regards Ole.
1188.49 Second WindowLEVERS::DRAGONThu Jul 07 1994 09:0610
    
    Ole,
    
    	You might want to try removing power for less than 9 seconds and
        then again for greater than 9 seconds. The MAM takes about 9
        seconds to recalculate power. This may provide more clues as to
        the problem.
    
    Just a thought,
    Bob
1188.5Bridge needs to be returned and analyzed....NACAD2::BATTERSBYThu Jul 07 1994 14:224
    Ole, I'll be contacting you off line. I think we ought to get 
    that bridge back here for analysis.
