How to Access a Configured Rack PDU
14 Switched Rack PDU Installation and Quick Start
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 high-security
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
E NTER
:
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 high-security access.
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.
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.

See the User’s Guide for more information on configuring
and using SSH.
Note
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
SNMP option of the Network menu.
