Rack Mounting
Refer to instructions packaged with the Rack Mount Hardware Kit for specific installation
information.
Note: If you plan to use digital audio, be sure to change the configuration of the Analog/Digital
Audio Jumpers inside the unit before mounting the Image Server in a rack. The jumpers are factory
set to the Analog audio position. For more information about changing the jumpers, see
Analog/Digital Audio Selection on page 106.
There are four adhesive-backed rubber feet on the Image Server, which may be removed when
rack mounting the unit.
Generally, the Image Server will be mounted in a 19” rack enclosure having 10-32 tapped holes.
The Image Server can be adapted to rack enclosures having untapped round or square holes by
using the nuts and washers included with the mounting kit.
Cables attached to the rear of the Image Server should be supported by the rack mounting rails.
Do not support substantial cable weight from the Image Server.
Keep the air vent slots on the sides of the Image Server free of obstructions.
Remove the front panel to expose the rack screw slots. Fasten the Image Server into the rack using
10-32 flat-head Phillips screws (provided). Replace the front panel. Tighten the front panel access
screws.
Important Information on Equipment Cooling
When many pieces of equipment are mounted in an equipment rack, a considerable amount of
heat may be produced, which must be removed efficiently. Further, a lower operating temperature
will make equipment operate more reliably, and it will last longer. In the extreme case, excessive
temperatures cause rapid equipment failure, and damage which can be difficult to repair.
Heat in an equipment rack should be removed by forced air. This is often accomplished by
blowers installed in the top of the rack, venting into the room. An alternative is to draw hot air
from the top of the rack into an air-conditioning return duct, and not vent it into the equipment
room; cold air should be ducted into the bottom of the rack.
The optimum air temperature for cooling electronic equipment is 25° C (72° F). When many
pieces of equipment are contributing to the heat load, a substantial air-flow will be needed, and the
inlet temperature may need to be lower.
Check These Points
• Are all ventilation holes in the Image Server free of obstruction?
• Can blowers or HVAC system adequately remove heat from the equipment rack?
• Have you measured the actual temperature inside the rack? Do this near the top.
• Verify that the HVAC system is not on a timer that can shut off on weekends or holidays.
• What procedures are in place to protect the equipment when the HVAC system fails?
