APC Fan SNMP and Modbus Operations for ACSC100 Model

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 Central or 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.

The Modbus register map is also available on the APC Web site, www.apc.com.
