A major bug in the microcode revision 08C3/A-Z when connecting from a HCS or any SSL secured connection like SNM2 to an AMS2x00 system.
A controller outage would be the effect.
Switch secure (SSL) connections in HCS,SNM2 etc. to none-secure!
Should a controller outage occure a „Dummy-Replacement of this controller should clear this problem.
Omit this MC-Level in any case!
Either stay beyond or upgrade to 08C3/D or any later Version where this bug is patched.
