Option Description
access To activate changes to any of these selections, log off from the PDU:
• Disable: Disables access to the Web interface. (You must use the command line interface to re-
enable access. Select Network and Web/SSL/TLS. Then for HTTP, select Access and Enabled.
For HTTPS access, also select Web/SSL and Enabled.)
• Enable HTTP (the default): Enables Hypertext Transfer Protocol (HTTP), which provides Web
access by user name and password, but does not encrypt user names, passwords, and data during
transmission.
• Enable HTTPS: Enables Hypertext Transfer Protocol (HTTPS) over Secure Sockets Layer
(SSL). SSL encrypts user names, passwords, and data during transmission, and authenticates the
PDU by digital certificate. When HTTPS is enabled, your browser displays a small lock icon.
See “Creating and Installing Digital Certificates” in the Security Handbook on the APC Web site,
www.apc.com, to choose among the several methods for using digital certificates.
HTTP Port: The TCP/IP port (80 by default) used to communicate by HTTP with the PDU.
HTTPS Port: The TCP/IP port (443 by default) used to communicate by HTTPS with the PDU.
For either of these ports, you can change the port setting to any unused port from 5000 to 32768
for additional security. Users 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://152.214.12.114:5000
https://152.214.12.114:5000
ssl cipher
suites
Enable or disable any of the SSL encryption ciphers and hash algorithms:
• DES: A block cipher that provides authentication by Secure Hash Algorithm.
• RC4_MD5 (enabled by default): A stream cipher that provides authentication by MD5 hash
algorithm.
• RC4_SHA (enabled by default): A stream cipher that provides authentication by Secure Hash
Algorithm.
• 3DES: A block cipher that provides authentication by Secure Hash Algorithm.
ssl certificate Add, replace, or remove a security certificate.
Status:
• 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, /
sec on the PDU.
• Generating: The PDU is generating a certificate because no valid certificate was found.
• Loading: A certificate is being activated on the PDU.
• Valid certificate: A valid certificate was installed or was generated by the PDU. Click on this
link to view the certificate’s contents.
If you install an invalid certificate, or if no certificate is loaded when you enable SSL, the
PDU generates a default certificate, a process which delays access to the interface for up to
five minutes. 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: Enter or browse to the certificate file created with the Security
Wizard.
See “Creating and Installing Digital Certificates” in the Security Handbook on the APC Web site,
www.apc.com, to choose a method for using digital certificates created by the Security Wizard or
generated by the PDU.
Remove: Delete the current certificate.
