Web access screen
Path: Configuration > Network > Web > Access
Use this option to configure the access method for the Web interface. (In order to activate any changes here,
you must reboot the NMC. See “Network on Control menu” on page 25).
You can enable access to this UI through either HTTP or HTTPS or through both, by using the Enable check
boxes. HTTP is disabled by default, and HTTPS is enabled by default. HTTPS encrypts user names,
passwords, and data during transmission; HTTP does not.
HTTPS also authenticates the NMC by digital certificate. See “Creating and Installing Digital Certificates” in the
Security Handbook available on the APC website to see how to use digital certificates.
For the ports, you can change the setting to any unused port for additional security; the range is 5000–32768.
You must then use a colon (:) in the address field of the browser to specify the port number. For example, for a
port number of 5000 and an IP address of 152.214.12.114:
http(s)://152.214.12.114:5000
Web SSL Certificate screen
Path: Configuration > Network > Web > SSL Certificate
Add, replace, or remove a security certificate. SSL (Secure Socket Layer) is a protocol used to encrypt data
between your browser and the web server.
The Status can be:
• Valid certificate: A valid certificate was installed or was generated by the NMC. Click on this link to
view the contents of the certificate.
• Certificate not installed: A certificate is not installed, or was installed by FTP or SCP to an incorrect
location. Using Add or Replace Certificate File installs the certificate to the correct location: /ssl on
the NMC.
• Generating: The NMC is generating a certificate because no valid certificate was found.
• Loading: A certificate is being activated on the NMC.
If you install an invalid certificate, or if no certificate is loaded while SSL is enabled, the NMC
generates a default certificate, a process which delays access to the interface for up to one minute.
You can use the default certificate for basic encryption-based security, but a security alert message
displays whenever you log on.
Add or Replace Certificate File: Browse to the certificate file created with the Security Wizard. See “Creating
and Installing Digital Certificates” in the Security Handbook on the APC website to see how to use digital
certificates created by the Security Wizard or generated by the NMC.
Remove: Delete the certificate. See screen text also.
