Secure Connection Failed With HP BL460c Blades in a C7000

I recently picked up some used blade servers on ebay. The problem was though the onboard administrator on the C7000 recognized them, neither Firefox nor IE could manage the web component of the blade as the certificate was long expired and from an untrusted CA (HP's self signed CA.)

The error message was:

*my ilo site* uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. (Error code: sec_error_unknown_issuer)

Adding an exception for the certificate failed. I found this link:

Mozilla's support site

Basically, you close firefox, delete cert8.db and start firefox again. After that, add the exception.
