This section provides detailed instructions for replacing a failed power supply in the Synergy 1 control

may be indicated by the PANEL LED on the control panel.
Synergy 1 — Power Fail LEDs
When the PANEL LED is lit, it indicates that there is a fault with the primary or secondary power
supply for the Synergy control panel.
Replacing the Control Panel Power Supply
Use the following procedure to replace a Synergy 1 control panel power supply.
1. Power off the control panel power switches. If a redundant power supply is installed,
ensure that both switches are turned off.
2. Check the fuses. Each switch has an associated fuse holder that corresponds to the
proper power supply. The fuse rating is printed on the panel surface.
• If the fuse is blown, spare fuses are available in the spare parts kit, or from Ross
Video Technical Support.
• If the fuse is intact, replace it in the holder and continue with the next step.
3. Check that the main breaker for your AC supply has not tripped:
• If the breaker has tripped, reset it to restore power.
• If the breaker is intact, please continue with the next step.
4. Unplug all AC power cords from the AC outlets.
5. In order to gain access to the Synergy 1 panel power supplies, you must be able to lift the
cover of the control panel off the base. To do this:
• Gently flip the control panel onto its side on a clean, flat, static free surface.
• Locate the eleven screws on the underside of the tub, loosen and remove them, and
set them aside in a safe place.
• Gently place the panel back down on its base.
6. For this next step, ensure you have telephone books, or a similar thick, sturdy object
available with which to support the control panel cover.
• Raise the cover and slide the telephone books under the rear area of the side panels
to keep it raised and secure while you work.
• Ensure you have enough workspace to access the power supplies.
• Position a work light in the control panel tub, if necessary.
