NN47250-500 (320657-F Version 02.01)
Upgrading an individual switch using the CLI
1 Save the configuration, using the save config command.
2 Back up the switch, using the backup system command.
3 Copy the new system image onto a TFTP server.
For example, log on to http://www.nortel.com/support using a web browser on your TFTP server and
download the image onto the server.
4 Copy the new system image file from the TFTP server into a boot partition in the switch’s nonvolatile
storage.
You can copy the image file only into the boot partition that was not used for the most recent restart. For
example, if the currently running image was booted from partition 0, you can copy the new image only
into partition 1.
5 Set the boot partition to the one with the upgrade image for the next restart.
To verify that the new image file is installed, type show boot.
6 Reboot the software.
To restart a WSS and reboot the software, type the following command:
reset system [force]
When you restart the WSS, the switch boots using the new WSS Software image. The switch also sends the AP version
of the new boot image to APs and restarts the APs. After an AP restarts, it checks the version of the new AP boot image
to make sure the boot image is newer than the boot image currently installed on the AP. If the boot image is newer, the
AP completes installation of its new boot image by copying the boot image into the AP’s flash memory, which takes
about 30 seconds, then restarts again. The upgrade of the AP is complete after the second restart.
Upgrade scenario
To upgrade 2382 from WSS Software Version 5.0 to WSS Software Version 6.0, type the following commands.
WSS# save config
success: configuration saved.
WSS# backup system tftp://172.16.0.10/sysa_bak
success: sent 13628 bytes in 0.150 seconds [ 90853 bytes/sec]
success: received 13628 bytes in 0.146 seconds [ 93342 bytes/sec]
success: backup complete.
WSS# copy tftp://172.16.0.10/NT504105.001 boot1:NT504105.001
.........................................success: received 7441834 bytes in 106.899 seconds [ 69615 bytes/sec]
WSS# set boot partition boot1
Note. This example copies the image file into boot partition 1. On your switch, copy the
image file into the boot partition that was not used the last time the switch was restarted.
For example, if the switch booted from boot partition 1, copy the new image into boot
partition 0. To see boot partition information, type the show boot command.
