Cannot log into HP 7506 via console

[DanielSchulze]

Hi,

I am currently locked out of our core which consists of two 7506 chassis linked via IRF.  I can log in via SSH occasionally but very few commands can be used before it locks my session and everntually I run out of VTY connections.  This happens whether I log in via a Lan interface or the OOB Mgmt interface.  I have tried to reset the VTY connections while logged in.  The command takes, but the VTY user does not reset.  

I cannot connect via console.  I have read the manual and configured baud rate/vt100/etc...  I have tried putty as well as alternatives.  We also purchased the console cable model listed in the manual with no luck.

thanks
DS
