3488.0. "decswitch900ee firmware corruption" by KYPROS::SYMEONIDES () Thu Apr 25 1996 14:46

Dear all,


	Trying to upgrade the firmware of the decswitch900ee, the switch
has never passed the self test again.


	The story goes like that..I have a PC with HUBWATCH for win V4.1
connected to the port 2 of the 900ee using a crossover cable. The switch is
placed on slot 1 of the hub900. The slot has been assigned with an IP address
as well as the 900ee.

	In order to perform firmware upgrade, I clicked the TFTP icon and
the HUBLOADER icon. I have noticed that the current version of the 900ee 
firmware was v1.1.0 and the latest was v1.1.1, so I clicked LOAD. 	

	I watched the TFTP counter starting from 0 up to a number xxxx and
then it stopped. At the moment where the counter stopped, the hubloader screen
was updated showing both current and latest versions v1.1.1. This means that
the upgrade has been completed successfully. On the other hand, the message
status box in the hubloader screen showed that the switch was about to reset.

	From that time and then the 900ee has never passed selftest. The leds
which were on, was that of the power indicator and that of the # which was 
blinking. The result was that I could no more communicate with the 900ee.
Is there a way of recovery ?

	
I would appreciate any help.

    Uhm could you be more specific with *which*  # led is blinking and
    the rate of the blinking. It's important as this may possibly indicate
    (as I suspect) that the # led blinking is the port 1 # led and may be
    the unit doing a bootp because of the possibly corrupted image.
    The more I hear of HUBloader failures with upgrading modules, the
    less faith I have in the HUBloader product. 
    The alternative way to have upgraded the 900EE would have been to try
    an in-band load via the 900EE's console (redirected from the MAM
    console screen), and then doing an interactive load from the 900EE
    console screen.

	In order to clear up things about the leds, here is their status
    after the upgrade.
    
    Power led			        	on
    
    Module OK led		       		off
    
    Port state led for port 1  			blinking green(once per 8 secs)
    Port state led for port 2-6			off
    
    Network port activity for port 1		off
    Network port activity for port 2-6    	off

    Ok this to me is a clear indication that the bridge did not complete
    writing the image to flash or the image CRC check failed.
    It's doing a bootp. You'll have to set up a node (if there isn't one
    already), to act as a bootp server. Once you've verified that you
    have a bootp server on your extended LAN. Then verify that the bootptab 
    file or whatever its equivalent is on a PC, is set up to load the 900EE 
    image to it. Connect a cable from the port 1 AUI port to your active 
    LAN which the TFTP server is on. This is the default port used for 
    the bootp load path. If all is set up on the node designated as the
    TFTP server, the 900EE presumably should load the image configured
    on the TFTP server for the 900EE.
