Adtran AOS Upgrade

Adtran 924 IOS Upgrade

Start with saving the current configuration
904#copy run start

[edit]

Gather information of the unit you are working on
matrix#show version ADTRAN, Inc. OS version A1.04.00.E  !!!!!!!!!!!!!!omited!!!!!!!!!!!!!!!! Platform: Total Access 924 (2nd Gen), part number 4212924L1 !!!!!!!!!!!!!!omited!!!!!!!!!!!!!!!! (this tells me that the current version is A1.04.00E)

(this also tells me that I am working with a 924 non E 2nd generation unit)

[edit]

See if you have enough available memory for the new AOS or if you have to delete the current AOS and then upload the new AOS
924#sh flash 9966111 9212916-20A104.biz 10906 startup-config 10906 startup-config.bak 10121355 bytes used, 21519060 available, 31640415 total (in this case we have 21519060 bytes which is over 20MB of available space. this is more then enough of memory for the new AOS. On average a new AOS is about 1MB)

[edit]

TFTP the new AOS to the unit we are working on. While not having to delete the current AOS
924#copy tftp flash Address of remote host?74.1.111.59 [this is our TFTP server] Source filename?T900G2A-A2-03-00-SC-E.biz [this is the the AOS update for this particular unit] Destination filename? [T900G2A-A2-03-00-SC-E.biz] Initiating TFTP transfer...         Received 228352 bytes. Received 10042040 bytes. Transfer complete. 924# (complete and no error messages.)

[edit]

Verify the new AOS and move the current AOS as a backup all with one command in the configuration menu.
924#conf t 924(config)#boot system flash T900G2A-A2-03-00-SC-E.biz 9212916-20A104.biz verify Verifying images. Please wait... Primary image: T900G2A-A2-03-00-SC-E.biz Backup image: 9212916-20A104.biz 924(config)#end 924#

[edit]

Show version to make sure the new AOS will take effect on next reboot and the current AOS will become the backup.
924#show version !!!!!!!!!!!!!!omited!!!!!!!!!!!!!!!! Current system image file is "NONVOL:/9212916-20A104.biz" Primary boot system image file is "T900G2A-A2-03-00-SC-E.biz" Backup boot system image file is "9212916-20A104.biz"

Copy the running config to the unit again
