Metered Rack PDU
17
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 control console:
1. From a computer on the same network as the Rack PDU, at a command prompt,
type telnet and the System 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 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.
2. Enter the user name and password (by default, apc and apc for an Administrator, or
device and apc for a Device Manager, which is the same user account as Device
User in the Web interface).
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.
Local access to the control console
For local access, use a computer connected by serial cable to the Rack PDU through
the serial port on the front panel of the unit.
1. Select a serial port at the local computer, and disable any service that uses that
port.
2. Use the supplied serial cable (APC part number 940-0144A) to connect the
selected port to the serial port on the front panel of the Rack PDU.
3. Run a terminal program (e.g., HyperTerminal), and configure the selected port for
9600 bps, 8 data bits, no parity, 1 stop bit, and no flow control.
4. Press
ENTER, and at the prompts, enter your user name and password.
