Switched Rack PDU
132
– The server certificate that you upload to the Rack PDU enables SSL
to authenticate that data are being received from and sent to the
correct Rack PDU. This provides an extra level of security beyond
the encryption of the user name, password, and transmitted data.
– The browser matches the digital signature on the server certificate
that you uploaded to the Rack PDU with the signature on the CA
root certificate that is already in the browser’s certificate cache to
provide additional protection from unauthorized access.
• Disadvantages:
– Setup requires the extra step of requesting a signed root certificate
from a Certificate Authority.
– An external Certificate Authority may charge a fee for providing
signed certificates.
