1.0 Introduction
This section provides the general information for the Teledyne Paradise Datacom 7-Rack Unit
Solid State Power Amplifier (SSPA) Chassis. This includes a description of the unit and safety
precautions.
1.1 Description
The Teledyne Paradise Datacom 7RU Rack-Mountable SSPA Chassis employs a modular
design, which allows quick and easy replacement in the event of a catastrophic failure of one
of the SSPA components. These modular assemblies include: hot-swappable SSPA modules;
front and rear fan trays; and a rear panel controller card.
The indoor rack mounted unit contains an internal microprocessor which allows for full
monitoring and control from the front panel’s 2x40 Vacuum Florescent Display and push-
buttons, or via a remote serial (RS-232 or RS-485) or parallel connector.
The microprocessor monitors various voltages, currents and temperatures within the unit for a
full fault analysis. The user also has the ability to select additional faults related to the RF
output level, an optional reflected power level and operating temperature.
An internal attenuator allows up to 20.0 dB of attenuation to be applied to the RF signal.
Temperature compensation limits the amplifier’s output response from varying significantly
over the operating temperature. Also, the system contains input and output sample ports.
The power supply for the 7RU SSPA Chassis is a separate 3RU Power Supply Chassis,
which houses three power supply modules. Only two of these modules are required to power
the SSPA, therefore the third module is redundant. In the event of a power supply module fail-
ure, the amplifier system will not fail.
1.2 Specifications
Refer to the specification sheet in Appendix C for complete specifications.
1.3 Equipment Supplied
The following equipment is supplied with each unit:
• High Power SSPA Chassis RM (7 RU high)
• Power Supply Chassis (3 RU high) (standard)

1.5 Rack Mounting
The SSPA Chassis is designed to fit in a standard 19” wide EIA rack. The unit is 7 rack units
or 10.47 inches (266 mm) high by 33.75 inches (857.3 mm) deep (including connectors and
bus bar), and weighs 180 pounds (82 kg). The power supply chassis is 3 rack units or 5.25
inches (133.4 mm) high by 20.42 inches (518.7 mm) deep, and weighs 50 pounds (23 kg)
with all three power supply modules installed.
1.6 Shipment

1.7 Safety Considerations
Potential safety hazards exist unless proper precautions are observed when working with this
unit. To ensure safe operation, the user must follow the information, cautions and warnings
provided in this manual as well as the warning labels placed on the unit itself.
1.7.1 High Voltage Hazards
High Voltage for the purpose of this section is any voltage in excess of 30
volts. Voltages above this value can be hazardous and even lethal under
certain circumstances. Care should be taken when working with devices that
operate at high voltage.
• All probes and tools that contact the equipment should be properly insulated to prevent
the operator from coming in contact with the voltage.
• The work area should be secure and free from non-essential items.
• Operators should never work alone on high voltage devices. There should always be an-
other person present in the same work area to assist in the event of an emergency.

Operations Manual, 7RU SSPA Chassis 208528 REV F 11
• Operators should be familiar with procedures to employ in the event of an emergency, i.e.,
remove all power, CPR, etc.
An AC powered unit will have 115 VAC or 230 VAC entering through the AC power connect-
or. Caution is required when working near this connector, the AC circuit breaker, or the inter-
nal power supply.
1.7.2 High Current Hazards
Many high power devices are capable of producing large surges of current.
This is true at all voltages, but needs to be emphasized for low voltage
devices. Low voltage devices provide security from high voltage hazards, but
also require higher current to provide the same power. High current can
cause severe injury from burns and explosion. The following precautions
should be taken on devices capable of discharging high current:
• Remove all conductive personal items (rings, watches, medals, etc.)
• The work area should be secure and free of non-essential items.
• Wear safety glasses and protective clothing.
• Operators should never work alone on high risk devices. There should always be another
person present in the same work area to assist in the event of an emergency.
• Operators should be familiar with procedures to employ in the event of an emergency, i.e.,
remove all power, CPR, etc.
Large DC currents are generated to operate the RF Module inside of the enclosure. EX-
TREME CAUTION IS REQUIRED WHEN THE ENCLOSURE IS OPEN AND THE AMPLIFI-
ER IS OPERATING. DO NOT TOUCH ANY OF THE CONNECTIONS ON THE RF MOD-
ULES WHEN THE AMPLIFIER IS OPERATING. CURRENTS IN EXCESS OF 60 AMPERES
MAY EXIST ON ANY ONE CONNECTOR.
1.7.3 RF Transmission Hazards
RF transmissions at high power levels may cause eyesight damage and skin
burns. Prolonged exposure to high levels of RF energy has been linked to a
variety of health issues. Please use the following precautions with high
levels of RF power.
• Always terminate the RF input and output connector prior to applying prime AC input pow-
er.
• Never look directly into the RF output waveguide
• Maintain a suitable distance from the source of the transmission such that the power
density is below recommended guidelines in ANSI/IEEE C95.1. The power density
specified in ANSI/IEEE C95.1-1992 is 10 mW/cm2. These requirements adhere to OSHA
Standard 1910.97.
When a safe distance is not practical, RF shielding should be used to achieve the recom-
mended power density levels.

12 208528 REV F Operations Manual, 7RU SSPA Chassis
1.7.4 Electrical Discharge Hazards
An electric spark can not only create ESD reliability problems, it can also
cause serious safety hazards. The following precautions should be followed
when there is a risk of electrical discharge:
• Follow all ESD guidelines
• Remove all flammable material and solvents from the area.
• All probes and tools that contact the equipment should be properly insulated to prevent
electrical discharge.
• The work area should be secure and free from non-essential items.
• Operators should never work alone on hazardous equipment. There should always be an-
other person present in the same work area to assist in the event of an emergency.
• Operators should be familiar with procedures to employ in the event of an emergency, i.e.,
remove all power, CPR, etc.
1.7.5 Tipping Hazard
Always load equipment into a rack from the bottom up so that it will not become top-heavy
and tip over. Deploy your rack's anti-tilt bar to prevent the rack from tipping during equipment
installation.
The 7RU SSPA chassis is designed to be installed within a rack cabinet
which is placed on a level surface. Any attempt to install the unit into a
cabinet on an uneven surface, or to improperly load equipment into the rack
cabinet beginning at the top, may cause the cabinet to tip over, which may
result in bodily injury.

2.1.3.2 Access to Removable SSPA Modules
The 7RU chassis houses four SSPA module/heatsink assemblies behind the front panel. The
a system of rack slides allows the module/heatsink assemblies to be removed from the ampli-
fier chassis for maintenance.
A faulted module may be removed from the chassis without taking the amplifier offline. To
identify the faulted module, press the Main Menu key on the front panel, select 1.SysInfo
and press the Enter key. Press the Down Arrow (▼) key seven (7) times to view the opera-
tion condition of Module1, Module2, Module3 and Module4. Figure 2-5 shows the location of
each module.
With the front panel removed, uncouple the RF In connector from the faulted module, lift and
turn the compression latches on either side of the module assembly, and slide the unit out of
the enclosure by releasing the slide locks on either side of the module assembly. See Figure
2-5.
A new module/heatsink assembly may be inserted in place of the one removed. Insert the
replacement module/heatsink assembly into the rack slide. Carefully slide the assembly back
into the enclosure. To ensure the module/heatsink assembly is properly seated, lock the
compression latches and gently tug on the handles. The assembly should not slide forward.
Re-couple the RF In connector. Some system phase adjustment may be necessary to ensure
optimum power output. See Section 4.3 for a description of proper system phase adjustment.

2.2.8 Link Port (J8) [DB9(F)]
The 9-pin male connector J8 Link Port is used to link a SSPA with other units in a redundant
system in order to pass online/standby status information between them. Leave unconnected
unless specified otherwise.
2.2.9 Ethernet Port (J9) [RJ45]
This is a RJ45 connector with integrated magnetics and LEDs. This port becomes the primary
remote control interface when the Interface option is selected to “IPNet” as described in
Section 7.6.1.2. This feature allows the user to connect the SSPA to a 10/100 Base-T Local
Area Network and have full-featured Monitor & Control functions through a web interface. See
Table 2-4 for Ethernet port pin outs.
Note: IP address, Gateway address, Subnet mask, IP port and IP Lock
address needs to be properly selected prior to first use (see Appendix A
for details).
LED lamps on the connector indicate network status. A steady Green light indicates a valid
Ethernet link; a Yellow LED flashes during any data transfer activity (on both Transmit and
Receive paths).
2.2.10 Power Supply M&C (J12)
The DB9 connector is connected to the 3RU power supply chassis. The SSPA monitors the
status of the power supply chassis and alarms in the event of a power supply module failure.
Due to the nature of the N+1 redundant power supply, a failure will not take the amplifier off
the air.
2.2.11 Input Sample Port (Optional)
An optional RF input sample port is located to the left of the J1 RF Input connector on the rear
panel. This port provides a -10 dBc coupled sample of the RF input signal. It is a type N
female connector.
