Option Description
access To activate changes to any of these selections, log off from the Rack PDU:
• Disable: Disables access to the Web interface. (To re-enable access, log in to the command line
interface, then type the command http -S enable. For HTTPS access, type https -S
enable.)
• 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
Rack 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, available at
www.apc.com.
HTTP Port: The TCP/IP port (80 by default) used to communicate by HTTP with the Rack
PDU.
HTTPS Port: The TCP/IP port (443 by default) used to communicate by HTTPS with the Rack
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
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,
/ssl on the Rack PDU.
• Generating: The Rack PDU is generating a certificate because no valid certificate was found.
• Loading: A certificate is being activated on the Rack PDU.
• Valid certificate: A valid certificate was installed or was generated by the Rack PDU. Click on
this link to view the contents of the certificate.
If you install an invalid certificate, or if no certificate is loaded when you enable
SSL, the
Rack PDU 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: Enter or browse to the certificate file created with the
Security Wizard.
See “Creating and Installing Digital Certificates” in the Security Handbook, available at
www.apc.com, to choose a method for using digital certificates created by the Security Wizard or
generated by the Rack PDU.
Remove: Delete the current certificate.
