Boot PROM Upgrade Wizard
Use the Boot PROM Upgrade Wizard to easily upgrade the boot PROM images on your network devices.
To access the wizard, select Tools > Wizards > Boot PROM Upgrade Wizard from the menu bar or click
on the toolbar.
There are certain steps you must perform before you can upgrade your boot PROM images. 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 Boot PROM Upgrade Wizard can also be used to downgrade boot PROM to a previous
revision. Downgrading boot PROM 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 boot PROM to an earlier version, it is recommended that you
use one of the following two procedures:
Downgrade the boot PROM on a network device using the Boot PROM 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 boot PROM image
being downloaded. This will reset the device.
or
•
Downgrade the boot PROM on a network device using the Boot PROM 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 boot PROM 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 boot PROM 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 boot PROM 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
operation. When selecting your devices, make sure that any device with SNMP context has access
to the required MIBs, or select the device with default context (switch mode).
