Extron electronic manual Firmware Upgrade Installation, USP 405 Appendix

Firmware Upgrade Installation

In some cases the USP 405’s firmware may require replacement with an updated version. There are four user-replaceable firmware chips: U60 — the main microcontroller, U24, U67 and U68. Both U67 and U68 are replaced as a pair. The numbers are printed on the circuit board. We recommend that you send the unit in to Extron for service and updates.

CAUTION

Changes to firmware must be performed by authorized service personnel only. Some USP 405 firmware updates must be performed at the Extron factory.

Follow these steps to replace firmware in the USP 405:

1.Disconnect the AC power cord from the USP 405 to remove power from the unit.

To prevent electric shock, always unplug the USP 405 from the AC power source before opening the enclosure.

2.Remove the USP 405 from the rack or furniture.

3.Remove the cover of the USP (the top half of the enclosure) by removing the screws, then lifting the cover straight up.

Remove (13) screws from top and sides.

Lift cover straight up.

Removing the USP 405 cover

CAUTION

Do not touch any switches or other electronic components inside the USP 405. Doing so could damage the unit. 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.

4.Locate the firmware chip(s) to be replaced on the circuit board, as shown in the following picture.
