1UPS Network Management Card 2 User’s Guide
Command Line Interface (CLI)
How To Log On
Overview
To access the command line interface, you can use either a local, serial connection, or a remote connection
(Telnet or SSH) with a computer on the same network as the Network Management Card (NMC).
Use case-sensitive user name and password entries to log on (by default, apc and apc for a Super User, or
device and apc for a Device User). A Read-Only User cannot access the command line interface.
See the UPS Network Management Card 2 User’s Guide (for AP9630, AP9631) for more information on these
options.
If you cannot remember your user name or password, see “How to Recover from a Lost Password”
in the User’s Guide.
Remote access to the command line interface
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 Configuration menu, select
Network - Console.
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 that has access to network on which the NMC is installed, at a command prompt, type
telnet and the IP address for the NMC (for example, telnet 139.225.6.133, when the NMC
uses the default Telnet port of 23), and press
ENTER.
If the NMC 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 don’t 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 a Super User, or device and apc 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.
