The purpose of this post is to outline how to upgrade a Symbol 5×00 Wireless LAN switch. In the example provided we will upgrade a switch running v1.4.3.0-R12 to v2.1.1. This upgrade is a major upgrade in that it literally replaces the core operating system with Linux. The upgrade is done in two steps. The first step you upgrade to v2.1 and in the second step you upgrade to v2.1.1.
You’ll be using the CLI interface to perform the upgrade; there will be no need for the web Java GUI until after the upgrade is complete.

It’s advised to start out by backing up the switch configuration and then uploading that configuration to the TFTP server on the network. You’ll first need to delete the existing configuration file. (If the switch is a standby switch there is no need to backup the configuration file).

File: sw16-wireless-tlh.cfg copied successfully to 10.101.20.1
Once you’ve backed up the switch configuration you need to make room for the new image. Delete all the files from the flash memory. You can use the “dir” command and “del” command.

Now you can go ahead and download the new system image and accompanying files via FTP. I’ve already placed the system image on the FTP server. The following files will need to be downloaded from the FTP server (10.101.20.1); WS5000_v2.1.0.0-029R.sys.kdi, dominfo, PreUpgradeScript, WS5k_domfix.cfg. You can confirm that the file gets copied down by listing the directory contents using “dir”.

The next step is to execute the PreUpgradeScript and check if there is adequate space for the upgrade. You’ll need to enter “service mode” to execute the following commands. You can enter “service mode” by entering the command “service”. The password may either be “password” or the switch admin password.

Total Free Space on the System: 148 (in MB) OK. Required space to do the upgrade exists .. !!
If you receive the “OK” you can go ahead with the upgrade. It may be necessary (with Wireless LAN Switch 5000s) to run the “PreUpgradeScript freemem” prior to downloading the WS5000_v2.1.0.sys.kdi image. The 5000 switches only have 128Mb of flash space available.

Now you’ll need to wait.; it should take between 5 and 10 minutes for the switch to upgrade and reboot. After the switch has rebooted you can re-establish your telnet session;

You’re all done.
The only issue I’ve discovered is that you need to re-configure the SNMP community string and TIMEZONE on any upgraded switch.
Enjoy.
