Serial Digital Interface (SDI) Card Installation
The optional SDI input and output cards may be installed in the USP 405 if it
does not already have an input or output for a serial digital interface signal. We
recommend that you send the unit to Extron for service and updates. The
following picture shows the USP 405 with both input and output SDI cards
installed.
Changes to electronic components must be performed by authorized
service personnel only.
Follow these steps to install an SDI card in the USP 405:
1. Disconnect the AC power cord from the USP 405 to remove power.
To prevent electric shock, always unplug the USP from the AC power
source before opening the enclosure.
2. Remove the USP from the rack or furniture.
3. Remove the cover of the USP 405 (the top half of the enclosure) by removing
the screws, then lifting the cover straight up. See the top cover removal
diagram in the previous “Firmware Upgrade Installation” section.

CAUTION Do not touch any switches or other electronic components inside the
USP 405. Doing so could damage the USP. Electrostatic discharge
(ESD) can damage IC chips even though you cannot feel it. You must be
electrically grounded before proceeding with any electronic component
replacement. A grounding wrist strap is recommended.
