Infoblox supports upgrading firmware on the following NIOS-X physical servers:

- Dell VEP-1425
- Dell VEP-1485
- B1-212

To update the firmware on your NIOS-X physical servers, do the following:

1. Go to the *[Dell official website](https://www.dell.com/support/home/en-us/product-support/product/dell-emc-networking-vep1445-vep1485/drivers)*.
2. On the **Drivers and Downloads** page, click the down arrow to expand the firmware updater section.
3. In the expanded section, click the **View full driver details** link.
4. On the firmware updater page, navigate to the **Firmware Images** section, and then click **Download**.
5. On the firmware updater EULA page, read the license agreement, and then click **Accept** at the bottom of the page. This will initiate the automatic download of the update file. The downloaded file will be saved in a .zip format. Other file formats are not supported.
6. You can now install the firmware upgrade script via the debug-cli or an USB flash drive.

# Applying Firmware Updates Using the debug-cli

1. Log in to the debug-cli.
2. Enter **help** at the command prompt and look for the **firmware** command option.
3. Enter **firmware apply** at the command prompt to run the firmware apply command. Note that if the firmware version is already up to date, you will see the following message on the debug-cli console after running the **firmware apply** command. Otherwise, the system will upgrade the firmware to the latest version.
4. Enter **firmware info** at the command prompt to check the current firmware version.

# Applying Firmware Updates Using a USB Flash Drive

1. Download the firmware script zip file on to a USB flash drive.
2. Insert the USB drive in to the hardware appliance.
3. All supported NIOS-X physical servers running the latest ISO package will auto-detect the firmware script and update the firmware automatically.
