Installation Manual
Command Line Interface access - Telnet, SSH and Dial-in Access
You can access the command line interface through Telnet or Secure SHell (SSH),
depending on which is enabled. To enable these access methods, use the NMC 2
Web interface. By default, Telnet is enabled.
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 of the Network Management Card from
any computer on the same subnet:
1. At a command prompt, use the following command line, and press
ENTER:
telnet address
As address, use the Network Management Card’s 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) 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.
See the User Guide for more information on configuring and using
SSH.
Dial-in access via a modem (AP9635 only). You can use a modem to dial in
to the command line interface of the AP9635 NMC for Out of Band Management of
the UPS, when standard Internet access is not available. Once connected, the
interface, user accounts and user access rights are the same as Telnet or SSH access.
See the Command Line Interface Guide for more information on
configuring the AP9635 NMC modem for Out of Band Management
access, available on the Network Management Card Utility CD and on
the APC Web site, www.apc.com.
Simple Network Management Protocol (SNMP)
SNMPv1 only. After you add the PowerNet
®
MIB to a standard SNMP MIB
browser, you can use that browser to access the Network Management Card. All
user names, passwords, and community names for SNMP are transferred over the
network as plain text. The default read community name is public; the default read/
write community name is private.
