How to Access a Configured Rack PDU
Telnet/SSH | 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 Telnet/SSH option of the Network  | 
  | menu. By default, Telnet is enabled. Enabling SSH automatically  | 
  | disables Telnet.  | 
  | Telnet for basic access. Telnet provides the basic security of  | 
  | authentication by user name and password, but not the   | 
  | benefits of encryption. To use Telnet to access a Rack PDU’s control  | 
  | console from any computer on the same subnet:  | 
  | 1. At a command prompt, use the following command line, and press  | 
  | ENTER:  | 
  | telnet address  | 
  | As address, use the Rack PDU’s IP address or DNS name (if  | 
  | configured).  | 
  | 2. Enter the user name and password (by default, apc and apc for an  | 
  | Administrator, or device and apc for a Device Manager).  | 
  | SSH 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.  | 
  | See the User’s Guide for more information on configuring  | 
  | and using SSH.  |

SNMP | After you add the PowerNet MIB to a standard SNMP MIB browser,  | 
  | you can use that browser for SNMP access to the Rack PDU. The  | 
  | default read community name is public; the default read/write  | 
  | community name is private.  | 
  | If you enable SSL and SSH, disable SNMP. Allowing SNMP  | 
  | access compromises the high security environment of SSL  | 
  | and SSH. Administrators can disable SNMP using the  | 
  | Note SNMP option of the Network menu.  |
