How to Upgrade Firmware
Use the Firmware Upgrade Wizard to easily upgrade the firmware images on your network devices. The
wizard gives you the flexibility of performing an immediate upgrade or scheduling the upgrade to take place
at a later time. If you schedule the upgrade, the wizard will automatically perform the upgrade at the
scheduled time, and then alert you that the upgraded devices need to be reset via the Reset Wizard.

Preparing to Upgrade
There are certain steps you must perform before you can upgrade your firmware. The steps vary depending on
whether you are using a mapped file transfer server (as configured in the Services for NetSight Server view of
the Options window) or an alternate remote file transfer server (as configured in the Alternate Firmware
Servers view in the Options window) to perform the upgrade.
If you are using a mapped file transfer server:
You must have a TFTP or FTP server configured and running to perform the download operation. See
TFTP Server Setup or FTP Server Setup for instructions.
•
Set the file transfer method for the devices you wish to upgrade. See How to Set a File Transfer
Method for instructions.
•
Store the firmware images that you want to download in the default tftpboot\firmware\images
directory or a specified alternative firmware directory. See TFTP Server Setup or FTP Server Setup
for instructions on changing your firmware directory.
•
Discover your firmware images and display them in the Firmware Mgmt tab. See Firmware
Discovery for instructions.
•
If you are using an alternate remote file transfer server:
You must have the alternate server configured and running to perform the download operation. See
Configuring the Alternate Server for instructions.
•
Set the file transfer method for the devices you wish to upgrade. See How to Set a File Transfer
Method for instructions.
•
Store the firmware images that you want to download in a specified alternative firmware directory.•
Create firmware records to associate with the alternate server and add them to the Inventory Manager
database. In addition, you must assign the firmware record to the appropriate product families or
device types. See Creating and Assigning Firmware Records for instructions.
•
Specify which alternate server a device will use when performing firmware downloads. See Setting
the Firmware Server for instructions.
•
NOTE: The Firmware Upgrade Wizard can also be used to downgrade firmware to a previous revision.
Downgrading firmware is inherently risky due to possible feature differences between revisions.
