Digital Cinema Server Power Ratings

• AC Input: 100-240V~, 6-3A, 60-50Hz
Maximum Power Consumption: 300W

•

WARNING: MULTIPLE SOURCES OF SUPPLY; DISCONNECT ALL SOURCES BEFORE
SERVICING.

Digital Cinema Server Rack Mount and Thermal Information

• Maximum operating ambient temperature is 35°C.

• Never restrict the air flow through the devices’ fan or vents.

• When installing equipment into a rack, distribute the units evenly. Otherwise hazardous

conditions may be created by an uneven weight distribution.

• Connect the unit only to a properly rated supply circuit. Reliable earthing (grounding) of rack-
mounted equipment should be maintained

PROTECTING YOURSELF AND THE Digital Cinema Server

Never touch the AC plug with wet hands.
Always disconnect the Digital Cinema Server from the power supply by pulling on the plug, not the cord.

Version 1.0

Allow only a DTS Digital Cinema dealer or qualified professional engineer to repair or reassemble the
Digital Cinema Server. Apart from voiding the warranty, unauthorized engineers might touch live internal
parts and receive a serious electric shock.

Do not put, or allow anyone to put, any object, especially metal objects into the Digital Cinema Server.
Use only an AC power supply. Never use a DC power supply.
If water or any other liquid is spilled into or onto the Digital Cinema Server, disconnect the power and call

your DTS Digital Cinema dealer.
Make sure the unit is well ventilated and away from direct sunlight. To avoid damage to internal circuitry,

as well as the external finish, keep the Digital Cinema Server away from sources of direct heat (heater
vents, stoves, radiators, etc.)

Avoid using flammable aerosols, etc. near the Digital Cinema Server. They may damage the surface and
may ignite. Do not use denatured alcohol, paint thinner, or similar chemicals to clean the Digital Cinema
Server. They will damage the finish.

Modification of this equipment is dangerous and can result in the functions of the Digital Cinema Server
being impaired. Never attempt to modify the equipment in any way.

In order to ensure optimum performance of your Digital Cinema Server, select the setup location carefully
and make sure the equipment is used properly. Avoid setting up the Digital Cinema Server in the
following locations:

1. In a humid or dusty environment.

2. In a room with poor ventilation.

3. On a surface which is not level.

4. Inside a moving vehicle where it will be subject to vibration.

5. In an extremely hot or cold environment.

Removable Drives Warning

Removal of the hot swappable hard drives allows access to pins and traces supplying power to the hard
drive backplane. These are considered as energy hazards.

REMOVAL OF HARD DRIVES MAY ONLY BE PERFORMED BY TRAINED SERVICE PERSONNEL.

With regards to the energy hazard warning and removable drives,

2 Digital Cinema Server Recommended Operating

Conditions

Listed below are the recommended operation conditions for the Digital Cinema Server:

1. AC power to Digital Cinema Server should be feed through UPS, >=600VA per player, which
provides a logical signal that shows the power failure.

2. To shutdown properly the Digital Cinema Server, do the following:

• Go to “Menu/Logout” – click on “Logout”

• Then, click on the “Shutdown” button

3. Ensure that AC ground lines are CE/UL rated (for ohm resistance) for Digital Cinema 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 1Vac­dc to minimize ground current circulations through AES/EBU lines (Measurement done
between both chassis grounds with dual link & AES disconnected).

6. Installation of 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,

8. Operating ambient humidity should be between 10% and 85% Non-Condensing.

below –

make sure to recall the order of the hard disk drives (which one was on the
top, which one was in the middle and which one was on the bottom) in order to put them
back at the same location after cleaning.

Caution: Make sure to re-position each Hard Disk Drive in its previous place or

otherwise the RAID might get corrupted.

To take the hard disk drive out, just press the blue button to release the handle and then

5.1.3 2U Fans and Dolphin Fan Shock Mounts Visual Inspection

2U fans and Dolphin fan might be mounted on the rear panel using shock mounts (each shock
mount replaces a screw) as presented below:

First gap Second gap

Figure 19: Fan Shock Mount

Check that the fans are properly shock-mounted

by visual inspection only:

1. by looking at the rear panel: you should NOT see any first shock mount gap - see
picture (a) below - and

2. by verifying from the top of the unit that the fans are parallel to the chassis, as
presented in the picture (b) below:

(a) (b)

Figure 20: 2U Fan Shock Mounts Visual Inspection – Correct Installation

Caution: Do NOT take out the fans from the shock mounts (visual

inspection only).

If one shock mount is not properly attached, use your fingers to fix them as illustrated below:

Pull gently on the shock mounts

with your fingers

Figure 21: 2U Fan Shock Mounts Re-attachment Example

In case shock mounts need to be replaced, please refer to document called “Digital Cinema
Server Fan Shock Mounts Installation Procedure” (document number D2K.DP.000223.DRM) to
find additional guidance.

5.1.4 Noise from Fans and Rattling

Power on the unit while on the desk with the lid opened.
Listen to the noise (if any) coming from fans.
If such noise is coming from fans, the corresponding fan can be located by removing one by one

the fan connectors. When the connector corresponding to the noisy fan is removed, the noise
should stop.

One fan’s connector
removed

Figure 22: Fan’s Connector Removal

Then replace the fan with a fan having the same Part Number.
In this case, please refer to document called “Digital Cinema Server Fan Shock Mounts

Installation Procedure” (document number D2K.DP.000223.DRM) to find additional guidance
about how to shock mount new fans.

Note: If a fan rattles (or vibrates), you should replace it to avoid damage to the hard drives.
