This is what I got from Siemens. We double checked our 4000 in SONUS and found they did not change it. We are doing an upgrade at the end of the month so we only changed this yes. I have the info on all systems if anyone is interested.
Hicom 300, 9751-9006, HiPath 4000
The SONUS tables for the Hicom 300, 9751-9006 and HiPath 4000 products were updated in October 2006 with the new dates for the next 10 years. If the time does not automatically change on March 11, 2007, please enter a service ticket via Siemens Online (must be a registered user), or contact the Siemens Support Operations Center.
