5. In the Choose file dialog
box, locate and select
the firmware file you
downloaded to
C:\Program Files\Extron
\Firmware\System_5_IP

, and click the Open
button.
6. Click on the Web page’s Upload button to upload the firmware into the
switcher. It takes a while to load all the files into the switcher. You will not
see any on-screen indication when the upload has finished. Once the
firmware upload is completed, all the front panel buttons (if applicable) on
the System 5 IP and on any connected optional SCPs light/flash as the
switcher performs a reset.
7. If desired, you can now use the Global Configurator program to restore a
configuration from a previously saved file.
Updating FPGA Firmware
On rare occasions it may be necessary to upgrade the switcher’s field-
programmable gate array (FPGA) firmware. An Extron Applications Engineer can
help you determine if an FPGA update is needed.
Determining the FPGA version
To determine which version of FPGA firmware the switcher has, use
HyperTerminal to send the 32Q SIS command to the switcher.
Replacing the FPGA chip
The user-replaceable 8-pin FPGA chip is U8. It must be physically removed and
replaced. It cannot be updated via RS-232 or IP communication.
CAUTION Changes to firmware must be performed by authorized service personnel
only.
Follow these steps to replace firmware in the System 5 IP.
1. Disconnect the AC power cord from the System 5 IP to remove power from
the unit.
To prevent electric shock, always unplug the switcher from the AC power
source before opening the enclosure.
2. Remove the switcher from the rack, wall or furniture.
3. Remove the cover of the switcher (the top half of the enclosure) by removing
the screws, then lifting the cover straight up. You might need to remove
attached mounting brackets before lifting the cover.
CAUTION Do not touch any electronic components inside the switcher. Doing so
could damage the switcher. Electrostatic discharge (ESD) can damage IC
chips even though you cannot feel it. You must be electrically grounded
before proceeding with firmware replacement. A grounding wrist strap is
recommended.
