Rack ATS AP44xx Installation and Quick Start14
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 for basic access
Telnet provides the basic security of authentication by user name and password, but not the
high-security benefits of encryption. Telnet is disabled by default.
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
E NTER 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 the Super User).
NOTE: You will be prompted to change the password on first use.
SSH for high-security access
If you use the high security of SSL for the Web UI, 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. SSH is enabled by default.
See the Security Handbook or the User Guide on www.apc.com for more information on configuring
and using SSH.
SNMP
SNMP is disabled by default. You must be an Administrator or Super User to enable or disable SNMP
access. Go to Configuration > Network > SNMPv1 or SNMPv3 > Access in the Web UI, or use the
SNMP or SNMPv3 commands in the CLI. See the User Guide on www.apc.com for more information.
To use StruxureWare Data Center Expert or EcoStruxure to manage the Rack ATS, you must have
SNMPv1 or SNMPv3 enabled in the unit interface. For SNMPv1, Read access allows StruxureWare
devices to receive traps from the Rack ATS. Write access is required while you set the StruxureWare
device as a trap receiver. See your StruxureWare Data Center Expert or EcoStruxure IT documentation
for detailed instructions.
All user names, passwords, and community names for SNMPv1 are transferred over the network as
plain text. If your network requires the high security of encryption, disable SNMPv1 access and use
SNMPv3 instead.
SNMPv1
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 community name used as an identifier when SNMPv1 traps are sent to this
trap receiver. You can set a read community name and a read/write community name.
