15Rack ATS AP44xx Installation and Quick Start
Command Line Interface: Telnet and SSH
To access the command line interface, you can use either a local (serial) connection or a remote (Telnet
or SSHv2, depending on which is enabled) connection with a computer on the same network as the
Rack ATS. A Super User or Administrator can enable these access methods. Telnet is enabled by
default.
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 Rack ATS from any computer on the same
network:
1. At a command prompt, use the following command line, and then press
ENTER until the User
Name prompt appears (You may have to press
ENTER up to 3 times.):
telnet address
NOTE: For address, use the Rack ATS 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 User).
SSH for high-security access
If you use the high security of SSL for the web interface, use Secure SHell (SSH) to access the CLI. SSH
encrypts user names, passwords, and transmitted data. The interface, user accounts, and user access
rights are the same whether you access the CLI 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 Security Handbook or the User Manual on www.apc.com for more information on configuring
and using SSH.
SNMP
SNMPv1 only
After you add the PowerNet
®
MIB to a standard SNMP MIB browser, you can use that browser for SNMP
access to the Rack ATS. The default read community name is public; the default read/write community
name is private.
SNMPv3
NOTE: To use SNMPv3, you must have an MIB program that supports SNMPv3.
For SNMP GETs, SETs, and the trap receivers, SNMPv3 uses a system of user profiles to identify users.
An SNMPv3 user must have a user profile assigned in the MIB software program to perform GETs and
SETs, browse the MIB, and receive traps. The default settings are no authentication and no privacy.
