APC UPS Network Management Card 2 AP9630 - Manual (Page 20)

16 Installation Manual
Telnet and SSH
You can access the command line interface through Telnet or Secure SHell
(SSH), depending on which is enabled. To enable these access methods, select
the Administration tab, the Network menu on the top menu bar, and the
access option under Console on the left navigation menu. By default, Telnet is
enabled. Enabling SSH automatically disables Telnet.
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
E NTER :
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’s Guide for more information on configuring and
using SSH.
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.
