SAFETY PRECAUTIONS
There is always a danger present when using electronic equipment.
Unexpected high voltages can be present at unusual locations in defective
equipment and signal distribution systems. Become familiar with the
equipment that you are working with and observe the following safety
precautions.
• Every precaution has been taken in the design of your CRD 4900 to ensure
that it is as safe as possible. However, safe operation depends on you the
operator.
• Always be sure your equipment is in good working order. Ensure that all
points of connection are secure to the chassis.
• Never work alone when working in hazardous conditions. Always have
another person close by in case of an accident.
• Always refer to the manual for safe operation. If you have a question about
the application or operation call Sencore for assistance.
• WARNING – To reduce the risk of fire or electrical shock never allow your
equipment to be exposed to water, rain or high moisture environments. If
exposed to a liquid, remove power safely (at the breaker) and send your
equipment to be serviced by a qualified technician.
• To reduce the risk of shock the CRD 4900 must be securely connected
backplane in a frame that is connected to a mains socket outlet with a
protective earthing connection.
CAUTION – Danger of explosion if battery is incorrectly replaced. Replace only
with the same or equivalent type.
STATIC DISCHARGE
Throughout this chapter, please heed the following cautionary note:
ESD Susceptibility: Static discharge can cause serious damage to sensitive
semiconductor devices. Avoid handling circuit boards in high static environments such as
carpeted areas, and when wearing synthetic fiber clothing. Always exercise proper
grounding precautions when working on circuit boards and related equipment.

1.1 Product Introduction
The CRD 4900 is a modular chassis for Sencore’s line of professional receiver-
decoder cards. This 2RU chassis provides space for 10 hot-swappable cards while
also offering redundant power supplies.
Using separate internal 1Gbps network switch capabilities for both management and
MPEG/IP, the CRD 4900 simplifies installation by reducing the need for external
cabling and external IP switch ports. The internal genlock reference distribution also
allows full genlock synchronization to all cards in the chassis.
The Sencore card-based series of receiver decoders coupled with the new CRD
4900 chassis provides one of the most dense and simple options available for
customers looking to do mass decoding or turn-around of streams.
Supported AG Cards:
• AG 6000 4K UHD Receiver Decoder Card
• AG 5800 Advanced Receiver Decoder Card
• AG 4400 Receiver Decoder Card
• AG 2600 Receiver Card
1.2 Front Panel Overview
The CRD 4900 can be monitored from the front panel using the LCD screen, status
LEDs, and the SET button that are shown below. All hardware listed below comes
standard with the CRD 4900.

1.3 Rear Panel Overview
The CRD 4900 comes standard with all the hardware listed below except for the AG
card’s backplanes.
1. External Genlock Reference Input
2. Optional Dual Power Supplies
3. RJ45 Management Port
4. RJ45 MPEG-IP Port
5. AG Card Backplanes
Note: When changing AG Card Backplanes, only use screws of 1/4” length. Longer
screws can potentially cause damage to the backplane.
1.4 Cooling
The CRD 4900 is cooled via forced induction through the front of the CRD 4900
frame and exhausted through vents in the sides and rear of the chassis. The CRD
4900 is equipped with a temperature-controlled status indicator. If the external
temperature of the card exceeds 60° C a temperature alarm will be triggered, and
the description of the alarm will appear in the “Alarms” lists under the “Reporting” tab
in the web interface. Make sure provided blind plates are installed in empty slots to
ensure proper airflow for cooling.
1.5 Rack Information
The CRD 4900 is intended to be mounted in a standard 19” rack. It occupies 2RU of
rack space and the connections are all on the rear of the unit.

2.1 Rack Installation
To install the CRD 4900 into a rack use the following steps:
1. Determine the desired position in the rack for the CRD
4900 making sure that the air intake on the front of the
unit and the exhausts on the rear and sides of the unit
will not be obstructed.
2. Insert the rack mount clips into place over the mounting
holes in the rack.
3. Slide the CRD 4900 into position in the rack.
4. Secure the CRD 4900 to the rack by installing the four
supplied screws through the front mounting holes and
tightening.
2.2 Power Connection
Using the proper power connections is vital to the safe operation of the CRD 4900.
Only use the supplied 3-prong power connector or one with equal specifications.
NEVER tamper with or remove the 3
rd
– prong grounding pin. This could cause
damage to the CRD 4900, personnel, or property.
2.3 AC Power Connection
The CRD 4900 is intended for use at either 120V or 240V. The CRD 4900 comes
standard with one power supply unit, with a second optional power supply unit (PSU)
available for redundancy. To connect the power, use the following steps:
1. Locate the AC power supply unit and the AC power cord that was included with
the CRD 4900.
2. Open the frame door of the CRD 4900 by pressing and holding the door tabs that
are located at the front of the CRD 4900 and gently pull the door away from the
frame.
CRD 4900 – User Manual
Page 14 (38)
3. Insert the PSU in either PSU slots 1 or 2 as shown in the below picture.
4. Make sure that the PSU switch is turned on and close the frame door.
5. Make sure provided blind plates are installed in empty slots to ensure proper
airflow for cooling.
6. Locate a protected outlet (usually inside of the rack) to plug the male end of the
power cable into the female end located at the back of the CRD 4900.
2.4 Onboard Controls and LEDs
The CRD 4900 decoder card uses a combination of button controls and LED’s to
reboot or recover the card and provide local status information. Figure 1 shows these
controls and LEDs, and they are also briefly described in this section.

illuminates red when there is no power coming from one of the two PSUs.
The Power Status LED illuminates green when all installed PSUs are
provided correct power to the frame.
• Switch Controller Status LED: This illuminates red whenever an error in
the switch controller is currently active in the CRD 4900. Illuminates green
if the switch controller has no active errors.
Figure 2: View of Switch Controller controls
Mute Button:
