APC AP7900 Manual Do Utilizador

You can access the control console through Telnet or Secure SHell (SSH), 
depending on which is enabled. (An Administrator can enable these access 
methods through the 

 option of the 

 menu.) By default, 

Telnet is enabled. Enabling SSH automatically disables Telnet.

Telnet provides the basic security of 

authentication by user name and password, but not the high-security 
benefits of encryption. To use Telnet to access the control console from any 
computer on the same subnet:

1. At a command prompt, type 

telnet

 and the System IP address for 

the Rack PDU (when the PDU uses the default Telnet port of 23), and 
then press 

E

NTER

. For example: 

telnet 139.225.6.133

2. Enter the user name and password (by default, 

 and 

 for an 

Administrator, or 

 and 

 for a Device Manager).

If you use the high security of SSL for the 

Web interface, use Secure SHell (SSH) for access to the control console. 
SSH encrypts user names, passwords and transmitted data. 

The interface, user accounts, and user access rights are the same whether 
you access the control console through SSH or Telnet, but to use SSH, you 
must first configure SSH and have an SSH client program installed on your 
computer.

If the PDU uses a non-default port number (between 5000 
and 32768), you need to include a colon or a space 
(depending on your Telnet client) after the IP address and 
then enter the port number.
