Cause:
You must use the Root account user name and password to download the Essential Alerts Device Definition File (DDF) for the Rack Monitor 750. The Essential Alerts DDF is a secondary DDF used by DCE that defines the pre-configured alarms for which DCE will alert.

Resolution:
Use the Root account user name and password to download the DDF. The default user name is root. You set the password on first use. See the User Guide on www.apc.com for instructions to set or reset the Root password.
