APC ACRP100 User Manual

Use the options under Web on the left navigation menu to configure the following:

access

To activate changes to any of the following access selections, log off from and back on to the 
cooling unit:
• Disable: Disables all access to the Web interface. (You must use the control console to re-

enable access to the Web interface. Select Network and Web/SSL/TLS. Then for HTTP 

access, select Access and Enabled, and 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 over Secure Sockets Layer (HTTPS) to 

provide Web access. Secure Sockets Layer (SSL) encrypts user names, passwords, and data 

during transmission, and provides authentication of the cooling unit by digital certificate.

See “Creating and Installing Digital Certificates” in the Security Handbook on the 
Utility CD to choose among the several methods for using digital certificates.

When HTTPS is enabled, your browser displays a lock icon, usually at the bottom 
of the screen: 

HTTP Port: Identifies the TCP/IP port used for communication by HTTP with the 
cooling unit. The default is 80.

HTTPS Port: Identifies the TCP/IP port used for communication by HTTPS with 
the cooling unit. The default is 443.

You can change either port setting to the number of any unused port from 5000 to 32768 to 
enhance the protection provided by User Name and Password settings. You must then use a 
colon (:) in the address field of the browser to specify the non-default port number. For 
example, for port 5000 and the cooling unit IP address of 152.214.12.114, you would use one of 
these Web addresses:

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, providing 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.
