1.4(6c) 1.5(2) 1.5(4) 1.5(7c) 2.0(3d)

Description (partial)

Unable to SSH/HTTP to the CIMC of the C-series server, however the CIMC can be pinged.  Also will notice the fans in the server running at a higher rate.

Generic OS installed on the server is not affected.  Only out-of-band management.


If the affected device is an APIC running 1.0(4q) and higher, this may cause an issue where the APIC software is unable to read system-product-name and system-serial-number from SPROM. . This is sometimes seen during a planned upgrade from versions before 1.0(4q) to versions higher than 1.0(4q).

The timing of this can be variable, but it has been seen to occur after approximately 60 days.
