Installing the D9859 Transcoder
Rack Mounted
The D9859 transcoder is a 1U unit with connector access at the rear panel. The
transcoder is intended for mounting in a standard 19" rack with minimum 1U
spacing between units to allow adequate ventilation/air flow.
The D9859 transcoder is vented from front to back. Multiple units can be stacked in a
rack, provided that adequate cooling is available.
Cooling
The D9859 transcoder is cooled by the use of internal fans. The air intake is from the
front and the air outlet is on the rear.
Note: Adequate cooling must be provided equaling 110 W (maximum) at 25°C per
unit to avoid overheating.
CAUTION:
The inlet air temperature must not exceed 50°C/122°F at any time.
Grounding
You must ensure that the unit is properly connected to ground in order to meet
safety and EMC requirements. Before any other connection is made, the unit must be
connected to a protected ground terminal as described below:
Via the three wire power cord of the AC power supply. This connection is
mandatory.
In addition, via the protective ground terminal on the rear panel of the unit. This
connection provides additional protection of the equipment.
Mounting the D9859 Transcoder to a Rack
1
Mount L-brackets in the rack to support each D9859 transcoder to be installed.
2
Place the transcoder in its position in the rack.
3
Mount the transcoder securely to the rack by securing the mounting flanges to
the rack using the four screws provided.
4
Make sure the air outlet holes on the back of the transcoder are not obstructed to
allow air flow from the front to the back of the chassis.
