Firmware Upgrade Wizard
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.
To access the wizard, select Tools > Wizards > Firmware Upgrade Wizard from the menu bar or click
on the toolbar.
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. For instructions, see Preparing to Upgrade.
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.
Restoring configurations from different firmware revisions carries the same risk. Should you need
to downgrade your firmware to an earlier version, it is recommended that you use one of the
following two procedures:
Downgrade the firmware on a network device using the Firmware Upgrade Wizard. Do
not proceed to the Reset Devices portion of the wizard, instead select [Finish]. Restore an
archived configuration that was previously created with the firmware image being
downloaded. This will reset the device.

•
Downgrade the firmware on a network device using the Firmware Upgrade Wizard.
Complete the downgrade using the wizard Reset Devices screens. Clear NVRAM on the
device and reconfigure the network configuration parameters of the device using the local
console.
•
In addition, when downgrading firmware on SNMPv3 devices, it is possible that Inventory
Manager will lose contact with the device. SNMPv3 adds a level of difficulty to downgrade
operations, because counters and timers related to security features of SNMPv3 may get out of
sync. Following the downgrade, you will need to restart Inventory Manager to re−establish
contact with the device.
CAUTION: Prior to upgrading firmware on a device, it is recommended that you archive the latest
configuration for the device being upgraded. This will aid you in downgrading should you
choose to do so.
Device Selection Window
Use this window to select the devices to include in the firmware upgrade operation.
NOTE: If you have multiple tree nodes representing the same device but with varying SNMP contexts,
keep in mind that not all device contexts will provide access to the MIBs required to perform the
