Materials:
1. Laptop or other computer with RS-232 serial I/O port
2. Serial cable with DB9 male end and mating connector for the above

3. Communications software capable of XMODEM uploads
4. PC ServerSwitch 2x16 software update file
Flash Update Steps:
1. Download the FLASH file for the 2x16 from the Lightwave FTP site to
your Laptop or computer.
2. Connect the computer's serial port to the CONTROL IN port of the
PC ServerSwitch 2x16. [If the unit had been cascaded with other
units, the cascade connections must be broken. Each 2x16 unit must
be updated individually.]
3. Start the communications software. Configure the communications
parameters to 38,400 baud, 8 data bits, no parity, 1 stop bit, and DTE
(38.4K 8N1 DTE). Select the correct serial port (i.e., COM1) as the
I/O port if not already selected.
4. Access the 2x16's System Setup menu by pressing Cntl-Cntl on
any attached keyboard, or pressing the Scroll Lock key twice.
5. From the System Setup System Setup System Setup System Setup menu, press the <F1> <F1> <F1> <F1> key to access the
defaults/flash update menu. Press the F F F F key to start the FLASH
update mode of the PC ServerSwitch 2x16. To interrupt the FLASH
update mode, turn the 2x16 power off and back on.
6. Begin uploading the flash update binary file from the computer
attached to the CONTROL IN port to the PC ServerSwitch 2x16.
Once the
F F F F key has been pressed, the PC ServerSwitch 2x16 sends
a message through the serial port prompting the Terminal program to
send the binary update file.
7. The user selects the Flash file on the computer. It is assumed that
the file transfer begins, although there is no visible confirmation
through the user's computer screen that the flash update has begun.
After about two minutes, the file upload (from PC to 2x16) is
completed. If no response after 5 minutes, you must start over.
