The purpose of this post is to outline how to upgrade a Symbol 5x00 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.

Symbol Wireless Switch WS 5000 Series.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).

sw16r-wireless> del sw16-wireless.cfgNow 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”.

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.

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