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 InfraStruXure Central or InfraStruXure Manager to manage the
Network Management Card, you must have SNMPv1 enabled in the interface of the cooling unit. Read
access allows InfraStruXure devices to receive traps from the cooling unit. 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 InfraStruXure Manager to manage the Network Management Card, you must have 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’s 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
Use Modbus to view the Network Management Card through the interface of your building management
system. It is read-only.
The Modbus interface supports 2-wire RS-485, plus ground.
Note: Modbus can be configured to run at either 9600 or 19200 bps.
