Section 1: General Information

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 push­buttons, 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 fail­ure, 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)

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.

10 208528 REV F Operations Manual, 7RU SSPA Chassis

• 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 connect­or. Caution is required when working near this connector, the AC circuit breaker, or the inter­nal 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. EX­TREME CAUTION IS REQUIRED WHEN THE ENCLOSURE IS OPEN AND THE AMPLIFI­ER IS OPERATING. DO NOT TOUCH ANY OF THE CONNECTIONS ON THE RF MOD­ULES 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 pow­er.

• 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 recom­mended power density levels.

Operations Manual, 7RU SSPA Chassis 208528 REV F 11

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.

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.

20 208528 REV F Operations Manual, 7RU SSPA Chassis

2.2.12 Output Sample Port

The Output RF Sample Port, which is a type N female connector, is located to the right of the
J12 PS M&C connector on the rear panel. This port provides a -40 dBc coupled sample of the
RF output signal. A calibration sticker is located beneath the connector.

2.2.13 Power Switch

The rocker-type power switch is located near the center of the rear panel, beneath the (J2)
RF output.

2.2.14 DC Input Quick Connect Ports

Power to the 7RU SSPA Chassis is supplied by a separate power supply chassis (See Sec­tion 2.3). The power supply’s DC output is provided by cables permanently attached to the

Power Supply that connect to the SSPA’s internal bus-bar via a series of quick-disconnect
high current in-line connectors.

Simply connect the mating DC output cable quick-disconnect connectors to the positive and
negative power connecters at the rear of the chassis.

2.2.15 Removable Fan Assemblies

The exhaust fans on the rear panel are each secured by four (4) captive thumb screws. To
remove, loosen the screws and carefully remove the fan assembly from the chassis. Unplug
the fan power cord from the connector. Replace with part number L206332-2.

2.2.16 Removable Controller Card Assembly

The controller card assembly is located at the rear of the SSPA and includes the Switch (J3),
Serial Main (J4), Serial Local (J5), Programming (J6), Parallel I/O (J7), Link (J8) and Ethernet
(J9) ports.

To remove this card assembly, loosen the two restraining thumbscrews at the top left and
bottom right of the assembly. See Figure 2-7. Slide the assembly straight back from the
cavity, as shown in Figure 2-8. This exposes the SSPA module programming connectors.

Figure 2-7: Loosen the two retaining
thumbscrews.

Operations Manual, 7RU SSPA Chassis 208528 REV F 21

Figure 2-8: Remove the card to access
the programming connectors.

2.3 Redundant Power Supply Chassis

A separate power supply chassis is used to provide redundancy of the power supply to the
7RU SSPA chassis. The power supply is configured with a parallel set of modules. All of the
modules are active and share the load current supplied to the amplifier. The power supply
module current capacity is chosen such that at least one extra module is included over the
amplifier’s current requirement. This is to say that the power supply is n+1 redundant. The
amplifier will continue to operate normally in the presence of one power supply module fail­ure.

The power supply modules are all hot swappable from the front panel. Therefore, if there ever
is a power supply module failure, there is no need to remove the entire power supply chassis.
The failed module is simply removed via the front panel. The power supply module removal
can be performed with the system powered. This is to say that the modules are “hot swappa­ble”.

2.3.1 1RU (four-module) N+1 Redundant Power Supply

The 1RU power supply shelf can be mounted directly below and adjacent to the amplifier
chassis. The 1RU power supply chassis is configured as an N+1 redundant, hot swappable
power source utilizing four 2.5 kW power modules. In the event of a single power module fail­ure, the amplifier system will not fail.

2.3.1.1 AC Mains Connection

In keeping with the redundant architecture of the power supply, there are individual AC inputs
for each power supply module. DC Outputs are in a bus bar configuration. See Figure 2-9.

+ -

DC Outputs

Figure 2-9: 1RU Power Supply AC Line Inputs/Outputs

The standard 24V AC input configuration for the 2.5 kW power supply is 100-240 VAC single
phase, 47-63 Hz, 0.99 power factor per module. A separate AC input transformer could feed
each AC input.

The wiring identification is as follows:

• L1 - Brown

• Chassis Ground - Green/Yellow

• L2/N - Blue

2.3.1.2 DC Output Connection

The DC output is provided by eight (8) sets of cables attached to the Power Supply DC output
buss bars that connect to the SSPA via a series of quick-disconnect high current in-line
connectors.

Connect the mating DC output cable quick-disconnect connectors to the positive and negative
power connecters at the rear of the chassis. See Figure 2-10.

Figure 2-10: DC Output Cable, Quick-Connect to Rear of Amplifier

2.3.1.3 Power Supply Alarm Connection

Each power supply module has an alarm output. The power supply alarms are monitored by
the SSPA’s monitor and control system. This provides for local and remote alarm reporting in
the event of a power supply module failure. The module alarm outputs are open-collector
signals with a low level = fault logic level. Under normal operation the alarm outputs are in a
high impedance state.

Using cable L202583-1, connect the Alarms Port of the 1RU Power Supply to Port J12 of the
accompanying 7RU SSPA Chassis.

2.3.1.4 Alarm Configuration at the SSPA Chassis

The power supply alarms may be monitored via the SSPA Chassis front panel menu. See
Section 3.1.2.

A failure of one of the power supply modules results in a minor fault, and the Power Supply
Fault indicator on the front panel of the SSPA Chassis will light and the System Information
screen on Page 2 of the Main menu will indicate a Power Supply Fault. To clear the fault, re­place the faulted power supply module.

Operations Manual, 7RU SSPA Chassis 208528 REV F 23

2.3.1.5 Power Supply Module Removal/Replacement

A failed module can be changed without ever taking the system out of service. Simply lift the
release knob and pull the extraction handle until the module slides from the shelf. Slide the
replacement module into the empty slot until the module is flush with the front of the shelf.

Figure 2-12: Dual 1RU Power Supply Option

Each power supply has a single phase, universal AC input ranging from 90-264 VAC, 47-63
Hz and is power factor corrected to 0.99.

2.3.2.1 AC Mains Connection

The power supply chassis has a dual feed AC architecture. Power
module slots 0 & 1 are supplied via AC Feed 1 and power module
slots 2 & 3 are supplied via AC Feed 2. The AC connections on the
shelf are made via rear accessed compression style terminal blocks.
See Figure 2-13.

Connect the first line/hot to L1, the second line or neutral to L2/N
and the AC ground to GND. These terminal blocks will accept up to
a maximum of 10 AWG wire, and should be torqued to 6 in-lbs

Terminal block

2.3.2.2 DC Output Connection

The DC output is provided by eight (8) sets of cables attached to the Power Supply DC output
buss bars that connect to the SSPA via a series of quick-disconnect high current in-line
connectors. As shown in Figure 2-12, the outputs of the 12V supply plug into the two (2) in­puts at the far left and far right of the amplifier.

2.3.2.3 Power Supply Alarm Connection

The power supply alarm cable used with the dual 1RU power supply option is L210747-1, and
connects between the Alarms Port of each of the power supplies and Port J12 of the 7RU
amplifier. The cable connectors are labeled for easy identification.

Operations Manual, 7RU SSPA Chassis 208528 REV F 25

2.4 Forward Power Detector

The Forward Power Detector module allows the user to introduce a sample of the unit or
system Forward RF power from the waveguide output. The detector box circuitry will measure
the amount of RF power present in the sample, with a dynamic range of 20 dB starting at the
maximum RF output. The following connections are required in order to monitor the output
power from the front panel menu of the SSPA chassis. See Figure 2-14.

Figure 2-14: Forward Power Detector Module

2.4.1 J40 Forward RF Sample In [SMA (F)]

A Forward RF Sample may be fed into port J40 of the detector box from a cross-guide
coupler on the RF output.

2.4.2 J44 RS-485 Connector [DB9 (F)] (209922)

This DB9 female connector serves as the primary RS-485 (2 or 4 wires) serial remote control
interface connector. The detector box is included in the serial chain along with the amplifiers
in the system.

2.4.3 Quick Connect Power

The Forward Power Detector module is powered via the J7 Parallel Port of the SSPA, when
operating a standalone unit. In system configurations, the Forward Power Detector module is
powered via a Detector Power Cable that also links to Port J7 between two or more units.

3.1.1 Sys Info Page 1

This is the amplifier main status information page. The page shows:

• Amplifier attenuation measured in dB ( Atten. (dB): XX.X) with accuracy of 0.1dB;

• Forward RF Power, measured in either dBm with resolution of 0.1dBm, or Watts

with a resolution of 0.1 Watts

• Alarms presence, "FAULT!" or "None" will be displayed depending on the state of
unit;

• Reflected RF Power, measured in either dB with resolution of 0.1dBm, or Watts
with a resolution of 0.1 Watts. Displays “N/A” if unavailable.

3.1.2 Sys Info Page 2

This page shows a variety of alarm states which may be present within the unit. Fault values
could be "Fault", "Normal" and "N/A"

• PS - power supply alarm, displays "Normal" if amplifier power supplies are normally
operational and "Fault" if one or more power supplies failed.

• LowRF - low RF fault;

• Fan - cooling system failures;

• Aux. - Auxiliary fault condition;

• VSWR - High Reflected power fault;

• BUC - Block Up converter fault.

If the fault condition doesn't apply to the amplifier configuration it will display "N/A" for "Not
Available".

3.1.3 Sys Info Page 3

This page displays miscellaneous information related to the redundancy operation and the
unit mute status.

• RFSW1 - state of RF switch 1, possible values - "Pos1" Pos2" "N/A", "Fault";

• RFSW2 - state of RF switch 2, possible values - "Pos1" Pos2" "N/A", "Fault";

• State - Unit online state, possible values "Online", "Standby";

• Mute - Amplifier mute state, possible values "Clear", "Set";

• Prior - Priority polarization select (1:2 Mode Only);

• PolSel - Current Polarization output (1:2 Mode Only)

3.1.4 Sys Info Page 4

This page displays various amplifier settings:

• Prtcl. - unit’s active remote control protocol. The value can be set to "Terminal", if
terminal mode protocol is currently active and "Normal" for string I/O type protocol.

• Baud - selected baud rate for remote control serial port. Selection: "2400", "4800",
"9600", "19200", "38400";

• Intrfc. - selected serial port interface. Selection: "RS232", "RS485".

Operations Manual, 7RU SSPA Chassis 208528 REV F 29

• Addrs. - Amplifier’s remote control network address. Value could be in range from 0
to 254. Note: address 255 is reserved for global calls and shouldn't be used for an
individual unit’s addressing.

• Buzzer - Audible alarm availability. Displays "Dis" if disabled; "Enb" if enabled.

• Latch - Fault latch option selection. Displays "Dis," if disabled; "Enb" if enabled.

3.1.5 Sys Info Page 5

Page 5 shows settings related to the Amplfier 1:1 Redundant System operation.

• Mode - indicates unit operational mode. Value can be set to "1:1" for 1:1
redundancy mode and "Stdaln" for stand alone mode;

• Stby. - shows unit standby state selection. "Hot" for hot standby operation (amplifier
retains unmuted state during standby period) and "Cold" for cold standby (unit
always mutes itself in standby mode and unmutes when switched back on-line).

• Ctrl. - shows amplifier control style. "Local" - both local and remote control are
supported and "Remote" when only remote control provided (keypad locked);

• Switch - indicates switching style. "Auto" for automatic fault tracking/switching and
"Manual" if redundancy switching is provided by operator.

• Unit - redundancy topological factor. "HPA1" for unit connected to RF switch ports 1
or 4 (Online Position 1 of the RF switch). "HPA2" for unit connected to RF switch
ports 2 or 3 (Online Position 2 of the RF switch).

3.1.6 Sys Info Page 6

This page shows the status of the unit’s internal power supplies

• PS1(V) - main power supply 1 output voltage with resolution of 0.1V. Normal output
voltage should be in range of 11 to 13 V.

• PS2(V) - main power supply 2 output voltage.

• Boost1(V) - booster power supply 1 output voltage with resolution of 0.1V. Normal

range 24 to 30 V (typical 28V);

• Boost2(V) - booster power supply 2 output voltage.

• DC (A) - total DC current draw by RF modules from main power supply. Value

varies depending on the power level of the unit. If the amplifier is muted, current
normally drops to within the 0 to 5 A range.

3.1.7 Sys Info Page 7

This page shows RF module related faults and conditions.

• Regulator - RF module regulator low voltage fault. Values - "Fault" or "Normal";

• DC Current - low DC current fault. Values -"Fault" or "Normal";

• Temperature - high temperature fault. Values - "Fault" or "Normal";

• Temp.(C) - internal RF module plate temperature in Celsius.
