JDS Uniphase RS-232 specification

Appendix F – Performing a Firmware Update on the Web Xpander

**Note: This applies only to firmware versions prior to v1.6 July 16, 2003 (See Appendix G for updating firmware versions 1.6 and later)

The firmware is the software that runs embedded within the Web Xpander. Periodically, a new version of the firmware may be made available either to address issues found in a prior version or to provide new features and functionality.

To perform a firmware update on the Web Xpander, the following items are required:

•Rabbit Programming Ribbon Cable – Available from Rabbit Semiconductor. See the JDS Technologies web site (on the Web Xpander Download page) for more information.

•Rabbit Firmware Utility (RFU) – Available on the Web Xpander CDROM and the JDS Technologies web site (on the Web Xpander Download page).

•Latest Web Xpander Firmware – Available on the JDS Technologies web site (on the Web Xpander Download page).

•Latest Web Xpander Labeler - Available on the JDS Technologies web site (on the Web Xpander Download page).

In preparation for the firmware update, make sure you have successfully installed both the Firmware Utility and the latest version of the Web Xpander Labeler application. Both of these applications will appear on your Start menu in the Web Xpander folder.

The Web Xpander firmware is transferred via the Rabbit Programming ribbon cable. One end of this cable has a 9-pin serial connector (DB9) which connects to your PC com port. It may be easiest to temporarily replace the cable that is used by WinEVM with the programming cable. The other end of the cable has two 10-pin connectors, one marked “PROG” and the other “DIAG”. Connect the end marked “PROG” to the Web Xpander Rabbit sub-assembly board as shown in the figure on the next page.

*** IMPORTANT ***

It is very important to properly connect this cable to the Web Xpander. One side of the cable is marked with a red stripe. This stripe indicates Pin 1 and must align with the correct pin on the Rabbit sub-assembly board. Looking at the Web Xpander, you’ll notice a smaller circuit board (the Rabbit sub-assembly board) that contains the ethernet connector. In the corner of this board, you’ll see a 10-pin connector (2 rows of 5 pins). The pin closest to the corner of this sub-assembly is marked with a white triangle to indicate Pin 1. Carefully attach the programming cable making sure that all 10 pins slide smoothly into the connector.
