Performing a Boot ROM Upgrade on an AOS Unit

[#1]

Introduction

Some ADTRAN Operation System (AOS) products require the boot ROM to be a minimum revision to run the latest firmware.  The minimum boot ROM requirements are listed in the firmware release notes, which can be obtained from ADTRAN’s website.  If you require a Boot ROM upgrade, please contact ADTRAN Technical Support (support@adtran.com or 888-423-8726) to obtain a boot ROM file.

The following steps outline upgrading the boot ROM on an AOS product.

Copy the Boot ROM to the AOS Unit

In order to copy the boot ROM file to the AOS unit, you can upload the image via the web GUI Firmware page, or by using a TFTP server as shown below (TFTP servers can be downloaded free from the Internet).

1. You will first need to setup a TFTP server on a computer or server on the same network as the AOS device.  Copy the boot ROM to the same directory the TFTP server uses to host files.  (Typically, the boot ROM file naming convention is NXXXXB-boot-NN-NN-NN.biz).

Type the following commands to transfer the boot ROM file to the AOS unit:

# copy tftp flash 

Address of remote host? 10.10.10.2

Source filename? N1534v2B-boot-17.08.01.00.biz

Destination filename? [N1534v2B-boot-17.08.01.00.biz]

Transfer complete.

Flashing the Boot ROM

1. First, verify the proper file is stored on the AOS unit’s flash by typing the show flash command.  Then, to flash the boot ROM, type copy <filename> boot. This command has to be run at the enable prompt.
   

# show flash

2.  To verify the boot ROM was loaded properly, issue the show version command.  In the command output, the Boot ROM version will be listed as Boot ROM version NN.NN.NN.NN.  The AOS unit will need to be reloaded/rebooted for the change to take effect.
