APC AP89XX Manuel D’Utilisation

You can use the command line interface to view the status of and configure and manage the Rack PDU 

(and any connected Rack PDUs if using the Network Port Sharing Feature). In addition, the command 
line interface enables you to create scripts for automated operation. An Administrator has full access to 
the command line interface, a Device user and Outlet User have limited access, and a Read-Only user is 
completely restricted.

You can configure all parameters of a Rack PDU (including those for which there are not specific CLI 

commands) by using the CLI to transfer an INI file to the Rack PDU. The CLI uses XMODEM to 
perform the transfer. However, you cannot read the current INI file through XMODEM. 

To access the command line interface, you can use either a local (serial) connection or a remote (Telnet 
or SSH) connection with a computer on the same network as the Rack PDU.

You can access the command line interface through Telnet or SSH. Telnet is enabled by default. Enabling 

SSH disables Telnet.

To enable or disable these access methods, use the Web interface. On the Administration tab, select 
Network on the top menu bar, and then the access option under Console on the left navigation menu.

Telnet provides the basic security of authentication byuser name and 

password, but not the high security benifits of encryption.

To use Telnet to access the command line interface:

1. From a computer that has access to the network on which the Rack PDU is installed, at a 

command prompt, type 

telnet

 and the IP address for the Rack PDU (for example, 

telnet 

139.225.6.133

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

ENTER

.

If the Rack PDU uses a non-default port number (from 5000 to 32768), you must include a colon 
or a space, depending on your Telnet cliet, between the IP address (or DNS name) and the port 
number. (These are commands for general usage. Some clients do not allow you to specify the 
port as an argument and some types of Linux might want extra commands).

2. Enter the user name and password (by default, apc and apc for an Administrator, or device and 

apc for a Device User).

If you use the high security of SSL for the Web interface, use SSH for 

access to the command line interface. SSH encrypts user names, passwords, and transmitted data. The 
interface, user accounts, and user access rights are the same whether you access the command line 
interface through SSH or Telnet, but to use SSH, you must first configure SSH and have an SSH client 
program installed on your computer.
