8. Click the Upload button. A status bar, which shows the progress of the
upload, appears in the Firmware Loader window (figure 5-8). The firmware
upload to the switcher may take several minutes.
Figure 5-8 — Firmware Loader status indicator bar, switcher reset, and
firmware update
Once the status bar has progressed fully from left to right, the firmware loader
utility resets the switcher (figure 5-8).
If the firmware loader utility exits before the status bar has progressed
completely across the indicator window, try using a control cable with only
pins 2, 3, and 5 connected. If necessary, modify the cable by removing pins or
cutting wires.
9. When prompted, confirm that the firmware version displayed in the firmware
loader is correct. Click Ok in the Firmware Update prompt window.
10. Click the Exit button to exit the firmware loader utility.
The firmware loader utility increases the serial port's baud rate to 115,200 to
speed up the upload process. Occasionally, the firmware loader may be unable
to return the serial port to its earlier baud rate, in which case communications
with the switcher may not be possible. If you are no longer able to
communicate with the switcher after the firmware upload completes, see
"Selecting the rear panel Remote port protocol and baud rate" in chapter 3,
"Operation", on page 3-37.
