40 Upgrading the Firmware
CHAPTER 2
Upgrading the Firmware
The NSG ships with firmware and the web client installed. However,
Harmonic periodically releases firmware updates. To find out if the
provided firmware meets your needs or must be updated, contact
Harmonic Technical Support.
To upgrade a number of NSG devices use the MCT (NSG Mass
Configuration Tool). Refer to the MCT Online Help for details.
You can also upgrade individual NSG devices manually, as described in
the following section.
Updating the Firmware
Before starting the upgrade process, verify the following:
■
There is a BOOTP and TFTP setup in your network.
■
You set an IP address to the NSG unit.
■
You obtained the new NSG firmware provided by Harmonic Technical
Support. Firmware may be provided via the NSG release CD or
downloaded from the Harmonic FTP site.
To upgrade the firmware, do the following:
1. Copy the new firmware file to a directory accessible by the TFTP
server.
2. Via the control panel or Web client, verify that the option BOOTP
Enable is selected.
3. Via the Web client, verify that the software update option is selected.
4. Via the control panel or Web client, reset the NSG unit.
5. To determine whether upgrade is completed successfully, wait for the
reboot process to complete. Via the control panel or Web client,
verify that the device reports the same version number as specified in
the release notes enclosed with the new firmware.
