Using the Utility
Before You Begin
Before you begin the upgrade, verify that you can provide a proper connection to the UPS as follows:
S
If you are upgrading the UPS firmware through an RS-232 or USB port, connect only to the
UPS you intend to upgrade—even if you are using a multi-port PC. A single connection
ensures that the upgrade utility communicates only with the UPS that you intend to upgrade.
S
If you are using an Ethernet interface to upgrade the UPS firmware, verify the NMC IP
Address and SNMP Read Community values for the UPS you intend to upgrade. Correctly
entering these values ensures that the upgrade utility will know which UPS to upgrade, even
if there are several UPSs online at the same time.
NOTE:
Because the Dell UPS Upgrade Software utility receives UPS information through Simple Network
Management Protocol (SNMP), SNMP must be enabled to use the Dell Network Management Card as an
Ethernet interface to upgrade the UPS. Refer to the Dell Network Management Card (NMC) User's Guide for
more information.
NOTE:
You can use the Connect button on the Dell UPS Upgrade Software window to display UPS details and
verify that you are connected to the correct UPS before you begin upgrading the UPS firmware.
AC input must be available and within the UPS operating range to begin the upgrade.
