Appendix C: Replacing / Upgrading Your SD Card
In some instances you may want to upgrade or replace your SD card. For example:
 You have purchased the ISY’s Networking Module and need more storage for the
internal web server.
 You are experiencing a blinking ERR light which could indicated a bad SD card.
The ISY supports up to a 16GB SD card.
Once your SD card is replaced, you will need to re-load the firmware onto your ISY as
well as restore your configuration from a backup. Please be sure to have a good
backup before attempting an SD card upgrade.
Newer ISY
Newer ISYs have an externally accessible SD card. Simply unplug all cables from your
ISY, pull out the old SD card, and insert the new SD card. You will also need to reload
the firmware onto your ISY. Proceed to the paragraph labeled “Reloading The ISY
Firmware and Restoring From Backup”.
Older ISY
Older ISY’s have internal SD cards, so the unit must be taken apart for the SD card to
be replaced. Please proceed with caution, and only if you feel comfortable taking apart
your ISY.
There are 4 screws holding on the cover to the ISY. Remove those screws, and simply
slide the cover off. Once off you will see 4 screws holding the ISY’s circuit board to the
bottom of the ISY’s case. Simply unscrew all four screws, remove the ISY’s circuit
board with caution, and replace the SD card.
