text: **Attention:**Before generating a request, ensure that your current browser does not 
  have restrictions on the type of keys that are used for certificates. Some browsers limit 
  the use of specific key-types for security and compatibility reasons. 
  
  Also, consult your organization’s security policy to ensure that the key type you are 
  configuring is compliant. 
  
  Click**Generate Request**. 
  
  3. Save the generated request file. Until the signed certificate is installed, the Secure 
  Communications window shows that an outstanding certificate request exists. 
  
  **Attention:**If you must update a field in the certificate request, generate a new request 
  and submit it to signing by the proper certificate authority. However, this process 
  invalidates the previous certificate request and prevents the installation of the signed 
  certificate associated with the original request. 
  
  4. Submit the request to the certificate authority to receive a signed certificate. 
  
  5. When you receive the signed certificate, select**Update Certificate**on the Secure 
  Communications window again. 
  
  6. Click the folder icon to upload the signed certificate, as shown in Figure 4-38. Click 
  **Update**. 
  
  7. You are prompted to confirm the action. Click**Yes**to proceed. The signed certificate is 
  
  installed. Close the browser and wait approximately 2 minutes before reconnecting to the 
  management GUI. 
  
  **4.5.2 Generating a self-signed certificate**
  
  Complete the following steps to generate a self-signed certificate: 
  
  1. Select**Update Certificate**on the Secure Communications window. 
  
  2. Select**Self-signed certificate**and enter the details for the new certificate. Key type and 
  
  validity days are the only mandatory fields. Figure 4-39 shows some values as an 
  example. 
  
  **Attention:**Before creating a self-signed certificate, ensure that your browser does not 
  have restrictions on the type of keys that are used for certificates. Some browsers limit 
  the use of specific key-types for security and compatibility reasons. 
  
  Consult your organization’s security policy to ensure that the key type you are 
  configuring is compliant.
