Make The Bootcode Available; Establish Serial Communication With The Switch; Power-Cycle The Switch And Interrupt Self-Test - Symbol ES3000 Manual

2-4 ES3000 Advanced Concept Guide
The steps to upgrade the bootcode are
1. Make the bootcode available on a TFTP server.

2. Establish serial communication with the switch.

3. Power-cycle the switch and interrupt the self-test phase.
4. Download the bootcode file.
5. Install the bootcode.

2.3.1 Make the Bootcode Available

Symbol Technologies will make bootcode upgrades available through the Symbol support pages on
the web and, if needed, through other means of distribution. The PoE version of the ES3000 and the
non-PoE version of the ES3000 require, at this time, different versions of the bootcode.
After the bootcode is downloaded from Symbol Technologies, place the bootcode in the service
directory for any TFTP server on the same LAN as the ES3000 switch. There are many TFTP servers
available, some at no cost. The procedures in this section were tested using the Solar Winds TFTP
server for Windows, available at www.solarwinds.net.
2.3.2 Establish Serial Communication with the Switch
If needed, establish serial communication with the ES3000 switch. As stated above, the serial
communication is through a male DB9 connector on the front of the ES3000. The communication
parameters are 19200 baud, 8 data bits, no parity, one stop bit, hardware flow control.

2.3.3 Power-Cycle the Switch and Interrupt Self-Test

The bootcode upgrade can not be installed from the normal level of software on the ES3000. To install
new bootcode, power-cycle the switch. It will print out messages as it boots:
Booting...
Memory test......OK
Do not attempt to run PoE versions of the bootcode on
non-PoE versions of the switch or vice versa or the
switch may not be operable after the incorrect bootcode
is installed.
