APC AP7900 Manual Do Utilizador

Authentication of the server (in this case, the Rack PDU) occurs each time 
a connection is made from the browser to the server. The browser checks to 
be sure that the server’s certificate is signed by a Certificate Authority 
known to the browser. For this authentication to occur:

• Each Switched Rack PDU with SSL enabled must have a server 

certificate on the Rack PDU itself.

• Any browser that is used to access the Rack PDU’s Web interface 

must contain the CA root certificate that signed the server certificate.

If authentication fails, the browser prompts you on whether to continue 
despite the fact that it cannot authenticate the server. 

If your network does not require the authentication provided by digital 
certificates, you can use the default certificate that the Rack PDU generates 
automatically. The default certificate’s digital signature will not be 
recognized by browsers, but a default certificate enables you to use SSL for 
the encryption of transmitted user names, passwords, and data. (If you use 
the default certificate, the browser prompts you to agree to unauthenticated 
access before it logs you on to the Web interface of the Rack PDU.) 

An SSH host key authenticates the identity 

of the server (the Switched Rack PDU) each time an SSH client contacts 
the Rack PDU. Each Switched Rack PDU with SSH enabled must have an 
SSH host key on the Rack PDU itself.

Use the APC Security Wizard to create the following components of an SSL 
and SSH security system:

• The server certificate for the Switched Rack PDU, if you want the 

benefits of authentication that such a certificate provides.You can 
create either of the following types of server certificate:
