As address, use the IP address of the Network Management Card 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 control console. SSH encrypts user names, passwords, and transmitted data.
The interface, user accounts, and user access rights are the same whether you access the control console
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.
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.
SNMPv3 only: For SNMP GETs, SETs, and 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.
NOTE: To use SNMPv3, you must have a MIB program that supports SNMPv3.
NOTE: The Network Management Card supports only MD5 authentication and DES encryption.
SNMPv1 and SNMPv3: To use StruxureWare Data Center Expert to manage the Network Management Card,
you must have SNMPv1 enabled in the unit interface. Read access allows InfraStruXure devices to receive
traps. Write access is required while you set the InfraStruXure device as a trap receiver.
To enable or disable SNMP access, you must be an Administrator. Select the Administration tab, select the
Network menu on the top menu bar, and use the access option under SNMPv1 or SNMPv3 on the left
navigation menu.
FTP/SCP
You can use FTP (enabled by default) or Secure CoPy (SCP) to transfer downloaded firmware to the Network
Management Card, or to access a copy of the event or data logs of the cooling unit. SCP provides the higher
security of encrypted data transmission and is enabled automatically when you enable SSH.
To use StruxureWare Data Center Expert to manage the Network Management Card, you must have the FTP
Server enabled in the Network Management Card. To enable or disable FTP Server access, you must be an
Administrator. On the Administration tab, select the Network menu on the top menu bar, and use the FTP
server option on the left navigation menu.
In the User Guide, see the following sections:
• To transfer firmware, see “File Transfers.”
• To retrieve a copy of the event or data log, see “Use FTP or SCP to retrieve log files.”
Modbus
Modbus lets you view the Network Management Card through the interface of your building management
system. The Modbus interface supports 2-wire RS-485, plus ground.
NOTE: Modbus can be configured to run at either 9600 or 19200 bps. It is already configured for 8 data bits, no
parity, and 1 stop bit, which are not changeable.
