16. Upgrading VMR/NPS Firmware
When new, improved versions of the VMR/NPS firmware become available, either the
Firmware Upgrade Utility (recommended) or the "Upgrade Firmware" function (Text
Interface only) can be used to update the unit. The following section describes the
procedure for updating the VMR/NPS unit using the Firmware Upgrade Utility or the
Upgrade Firmware function.
16.1. WMU Enterprise Management Software (Recommended)
The preferred method for updating VMR/NPS units is via the WMU Enterprise
Management Software that is included with the unit. 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:
http://www.wti.com/t-product-manuals.aspx
Note that in order to use the WMU software, the firmware version for the VMR/NPS must
be at least v1.48 or higher. When upgrading older VMR/NPS units that feature pre v1.48
firmware, 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:
ftp://wtiftp.wti.com/pub/TechSupport/Firmware/Upgrade_Utility/
Please refer to the documentation included in the zip file for further instructions.
16.2. The Upgrade Firmware Function (Alternate Method)
The Upgrade Firmware function provides an alternative method for updating the VMR
firmware. Updates can be uploaded via FTP or SFTP protocols.
Notes:
• The FTP/SFTP servers can only be started via the Text Interface.
• All other ports will remain active during the firmware upgrade procedure.
• If the upgrade includes new parameters or features not included in the
previous firmware version, these new parameters will be set to their default
values.
• The upgrade procedure will require approximately 15 minutes.
1. Obtain the update file. Firmware modifications can either be mailed to the
customer, or downloaded from WTI. Place the upgrade CDR in your disk drive or
copy the file to your hard drive.
2. Access Text Interface command mode via Serial Port, Telnet or SSH client session,
using a username/password and port that permit Administrator level commands.
