Installation:

WTI Centralized Management Software (WMU), is the preferred method for installing firmware updates on WTI devices.  The WMU software allows you to manage firmware updates for multiple WTI units from a single interface. 

For a description of the process for managing firmware updates via the WMU, please refer to the WMU user's guide, which can be downloaded from the WTI User's Guide Archive at:

https://www.wti.com/pages/manuals-documentation

Note that in order to use the WMU software, the existing firmware version for the WTI Device(s) must conform to the following standards:

•	Console Server Products (DSM, CPM, REM, TSM and RSM Series):  Firmware Version v6.23 or higher.  
•	Switched PDU Products (VMR, NBB, NPS, RPC and CCM Series):  Firmware Version 1.48 or higher.
•	Data Fallback Switch Products (AFS Series):  Firmware Version 2.30

When upgrading older units that are running firmware versions that are earlier than the standards listed above, it is recommended to use the WTI Firmware Upgrade Utility.  A zip file that contains the installation files and other documentation for the WTI Firmware Upgrade Utility can be downloaded from WTI's FTP server, located at:

https://ftp.wti.com/pub/TechSupport/Firmware/Upgrade_Utility/

Please refer to the documentation included in the zip file for further instructions.

In addition to the WMU and WTI Firmware Upgrade Utility, the /UF command can also be used to install firmware upgrades.  For more information on the /UF command, please refer to the user’s guide for your WTI device.
