2 Digital Cinema Server Recommended Operating
Conditions
Listed below are the recommended operation conditions for Doremi digital cinema servers:
1. AC power to the unit should be feed through UPS, greater than or equal to 600VA per player,
which provides a logical signal that shows the power failure.
2. To properly shutdown the server, do the following:
• Go to Menu/Logout and click on Logout.
• Click on the Shutdown button.
3. Ensure that AC ground lines are CE/UL rated (for ohm resistance) for the server & projector
power connections.
4. Ground voltage difference from cinema player to projector should not exceed 1Vac/dc to
minimize ground current circulations through dual link HD-SDI lines (measurement done
between both chassis grounds with dual link & AES disconnected).
5. Ground voltage difference from cinema player to audio processor should not exceed 1Vac-dc
to minimize ground current circulations through AES/EBU lines (measurement done between
both chassis grounds with dual link & AES disconnected).
6. Installation of the cinema player in a typical protected rack enclosure to avoid physical shocks
and vibrations during player/disk operation.
7. Ambient air temperature at front and rear of cinema player should not exceed 35°C (95°F)
when operating unit.
8. Operating ambient humidity should be between 10% and 85% Non-Condensing.
