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 the command line interface:
1. From a computer on the same network as the Rack PDU, 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 client, 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 arguement and some may
require extra commands.)
2. Enter the user name and password (by default, admin and admin for an
Administrator, or device and device for a Device User).
SSH for high-security access. 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.
If you cannot remember your user name or password, see
Recovering from a Lost Password.
