APC Understanding SNMP, FTP, SCP, and Modbus in Environmental Manager

Note: To use SNMPv3, you must have a

MIB program that supports SNMPv3.

The Main Module supports only MD5 authentication and DES encryption.

SNMPv1 and SNMPv3. To use InfraStruXure Central or InfraStruXure Manager to manage the Main Module on the public network of an InfraStruXure system, you must have SNMPv1 enabled in the unit interface. Read access allows InfraStruXure devices to receive traps from the Main Module. 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 and SCP

You can use FTP (enabled by default) or Secure CoPy (SCP) to transfer downloaded firmware to the Main Module, or to access a copy of the event or data logs of the Main Module. SCP provides the higher security of encrypted data transmission and is enabled automatically when you enable SSH.

To use InfraStruXure Manager to manage the Main Module, you must have FTP Server enabled in the Main Module interface. 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 Environmental Manager: Main Module 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

Modbus lets you view the Main Module 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.

To access the Modbus register map, go to the APC Web site, www.apc.com, and search for part number AP9340.
