Appendix A
Firmware Upgrade Using an External Server
A.1 Upgrading the Firmware of a Single Device
NOTE: To upgrade from any version older than version 2.4.1 to version 2.4.1 and higher, you should use
MCT. MCT allows a smooth and problem-free process. To upgrade, you can use either MCT Pro or MCT Lite
which fully supports the NSG firmware upgrade feature. MCT Lite is provided by Harmonic free of charge.
To take advantage of other MCT features, purchase MCT Pro.
A.1.1 Before Upgrading
Before upgrading, prepare the following:
• HTTP Server - Firmware upgrade of NSG 9000-6G is based on HTTP download and
requires an HTTP server. Installing and configuring an HTTP server is a one time
procedure. For instructions on how to install and configure an HTTP server, see Upgrade
Server Installation and Configuration on page 140.
• Firmware package - Obtain the new firmware zipped files from Harmonic's FTP site. New
firmware packages are distributed as self-extracting ZIP archives. Starting from firmware
version 2.4.1, the NSG firmware distribution includes two separate self-extracting
archives that are separately executed:
Main firmware archive - when executed, this file extracts the firmware package to a
folder which is named the same as the version number (e.g. 2.4.1.13-1), under the
X:\HTTPROOT\Harmonic\NSG9K6G\X.Y.Z.BB-1 where x.y.z.bb-1 represents unique
identification of the package, for instance 2.4.1.13-1. x.y.z are identical to the official
name of the release.
NSG-Upgrade archive - this archive, which is much smaller in size, holds various
software components that the NSG utilizes during the upgrade process. It must be
extracted separately from the main archive. When executed, this file extracts its
content to a folder named HTTPROOT\Harmonic\NSG9K6G\nsg-upgrade x.y.z-1
where x.y.z-1 represents version identification information, for example nsg-upgrade
1.0.6-1.
A.2 Upgrading Procedure
NOTE: In case the device is working in an EdgeCluster mode, refer, before you start upgrading, to
3.17.3 EdgeCluster Maintenance on page 72.
1. Make sure that you have either the Apache or the IIS HTTP server installed and
configured on your firmware repository server machine. See Upgrade Server Installation and
Configuration on page 140
2. Obtain the new firmware zipped files from Harmonic's FTP site.
3. Browse to the firmware files and double click the main firmware archive:
NSG9K-6G_X.Y.Z.BB-1.exe where x.y.z.bb-1represents version identification number.
The following message appears:
This self-extracting archive mounts the NSG9000-6G Firmware
package on your PC.
4. Click OK.
