I have a 4020 switch module in the back of a H-Class IBM BladeCentre. It's a new device and it came with 6.2.2b firmware and I need to downgrade it to 5.3.1a. I ran the upgrade procedure to take it to 6.1.0 which worked fine - however now I cannot log onto the device -non of the supposed default userid and passwords get me back onto the box .
Are there any known issues for password corruption going down to 6.1.0 ? and if not - what is the password recovery procedure for a 4020 I/O module switch.
Many thanks for your help all !

All username and password you listed here are incorrect.
For Blade Switch, is the corect username and pwd as below.
or see this DOC

Hi, my appologies, I should have added those to my list of passwords I'd tried and that didn't work. Are there any others and also, is it a known issue - password corruption ?
The links don't seem to mention password recovery for and I/O module blade ?
Many thanks for your advice so far.

this is not a pwd corruption during FOS Downgrade, probable a default password for USERID account was changed.
You need to login as
USERID and the current pwd.
--->>>The links don't seem to mention password recovery...
they don't ask for password recovery in the original threads.
for password recovery see this DOC here.
For serial port you need to use the Chassis Serial Port.

Thanks for the document link, I have a call open with IBM to get me console access to the I/O modules, as it currently only appears to work for the Blades in the chassis.
As to the password issue - I'm the admin and I can confirm the passwords were not set before these I/O mods were downgraded. These mods are brand new and I tested all the logon ID's before starting the downgrade. Also, just to prove this to myself, I tested the default passwords on the second new Brocade I/O module I have in this chassis, they worked fine. I then did the down grade from 6.2.2 to 6.1.0, tried to log on to the second blade and it locked me out.
There is something going on in the downgrade and I don't think it's as simple as a forgotten password.

With regard to getting console access to the 4020 via the H Class chassis I saw one of the Brocade experts on this forum on another post reply to a similar question with the following ?
"Is correct 4020 don't have a external Serial Port, you must connect trough the BladeCenter Serial Port, reboot and select in Boot menu Slot option in order to boot into the appropriate Blade/Blade slot..."
Can anyone on this forum expand on this and detail the process around rebooting the H Class and what menu's you're presented with that allow console access to the 4020.
