CPS3200U Upstream System – 23” Product Manual CPS3200U
1 Introduction
Overview
The CPS3200U is the premier upstream dc/dc converter for line powering FTTN networks. The 3200U contains 16 dc/dc
converter/limiter cards in a dense 2 RU shelf. Each card contains a pair of independent -48 Vdc input to ±190 Vdc
output converters with each output safety limited to 100VA. In addition, each output terminal is safety Ground Fault
protected. The cards are fully connectorized and insulator shielded, inrush current protected and completely hot
swappable, making card addition to in-service shelves in the field an easy, one step process. The converter card shelf is
completely front access, with all -48V input and RJ21 output connections made on connectors in front of the midmount shelf brackets. The alarm and communications connections are also on the front of the shelf.
The CPS3200U converter shelf meets the applicable requirements of these North American product standards:
UL60950-21, UL60950-1, Telcordia GR-3108-CORE, GR-1089-CORE, GR-487-CORE (converter shelf), and GR-063-CORE.
Summary
The CPS3200U Upstream System delivers power over telephone lines. The primary application is enabling the delivery of
video bandwidth data rates to residences over twisted pairs by allowing placement of powered electronics at an
acceptable distance from the residence.
48 Vdc Input, ±190 Vdc Output Converter/Limiter System distributes battery backed up power from existing -48V
battery backed up sites like Central Offices and Remote terminals to reliably power electronics near the home. It does
this by converting the -48V to a UL60950-21 safety approved + and – 190V current limited and ground fault protected
source. Each front access shelf provides 32 channels.

2 Product Description
Figure 1 Block Diagram -48V Fed CPS3200U Shelf
Basic block diagram of single converter shelf System
Operation
Power comes in as -48V and is distributed in an A and B redundant fashion to each of the converter cards and the
alarm card. There are two +/-190V circuits on each converter card. The circuits both boost the voltage and limit the
current as prescribed by UL60950-21 and GR-1089-CORE.
Warning: Ground faults or short circuits on the output do not permanently disconnect the output. The converter circuit
tests the line every 4 seconds and will re-energize if the wiring fault is cleared.
A serial communication bus links each converter to an alarm card at the end of each shelf.
The alarm card provides major and minor form C contacts, manages the converters and relays information to a Lineage
Power CPS6000 family controller using Galaxy Protocol over an RS485 bus. Up to 24 shelves can be controlled and
monitored by one CPS6000 family controller. The CPS6000 controller is WEB and SNMP capable.
Configurations
32 circuit, front access +/-190V shelves come in two configurations - airflow from bottom to top and airflow from top to
bottom. A single IP drop can be used to manage up to 24 shelves or 768 circuits.

Installation Category
CPS3200U output circuits are suitable for connection to telephone lines that are equipped with primary lightning
protectors consistent with UL 497. The user must provide protection on each copper pair to a level corresponding to a
CommScope 3C*EW Gas tube primary protector or equivalent gas tube protector [For example: 3C3EW provides the
part in a red color]. This protector has a voltage breakdown range of 265-465 Volts and an impulse spark over range of
<265-700 Volts. The 5-Pin protector must be marked as a “special circuit” consistent with the marking protocol in the
users network. Protectors are provided by the telco customer.
Network equipment and components along the powering circuit shall have suitable insulation resistance at 200 Vdc
from each conductor to ground and a total insulation resistance suitable for 400 Vdc from line to line.

Max = Absolute Maximum Rating

These are maximum situations with each circuit loaded to 100W. No actual or engineered application would load
every circuit to this level. In the absence of detailed information about the network we would recommend using the
typical dissipation value of 21 Watts for most applications with 30W per card for highly loaded networks.

Precautions
When working on or using this type of equipment, the following precautions should be noted:
• This unit must be installed, serviced, and operated only by skilled and qualified personnel who have the necessary
knowledge and practical experience with electrical equipment and who understand the hazards that can arise
when working on this type of equipment.
• The equipment could be powered by multiple dc inputs. Ensure that the appropriate circuit protection device for
each dc input is disconnected before servicing the equipment. Do not disconnect permanent bonding provisions
unless all dc inputs are disconnected.
• DC inputs may be connected in parallel to power the dc-dc converters. Disconnecting one dc input will not
necessarily remove power from the bus. Make sure all battery power sources are also disconnected and/or follow
safety procedures while working on any equipment that contains hazardous energy/voltage.
• Hazardous energy and voltages are present in the unit and on the interface cables that can shock or cause
serious injury. Follow all safety warnings and practices when servicing this equipment. When equipped with
QS982A modules, hazardous voltages (+/-190Vdc) will be present on the output connectors and associated
interconnection cables.
In addition to proper job training and safety procedures, the following are some basic precautions that should always
be used:
• Use only properly insulated tools.
• Remove all metallic objects (key chains, glasses, rings, watches, or other jewelry).
• Wear safety glasses. Fuses can produce sparks. High energy levels on buses and distribution components can
produce severe arcing.
• Do not rely on simple volt meter tests to determine if the +/-190V output circuit is off line. Physically break the
circuit by removing the associated QS982A converter before touching the +/-190V RFT-V circuit. Confirmationtest each circuit for 5 seconds before touching. In some line fault modes, power is cycled on every 4 seconds. The
presence of a fault may make it difficult to determine if the circuit is online. Always physically break the circuit.
• Lock out and tag circuit breakers/fuses when possible to prevent accidental turn on.
• Be aware of potential hazards before servicing equipment.
• Identify exposed hazardous electrical potentials on connectors, wiring, etc. (note the condition of these circuits,
especially wiring).
• Use care when removing or replacing covers; avoid contacting circuits.

Installing the Baffle
Purpose: Redirect air coming into, and objects falling down toward, the FTTN shelf. Follow the steps in the table below to
attach a baffle above the FTTN shelves for all CO or customer premise applications. The baffle has two purposes: 1)
redirect air toward the back isle so that components located below the FTTN shelves will not over heat, and 2) Keep
objects from falling into the FTTN shelf. The baffle can either be fixed at a height above the Fan Shelf to allow for three
CPS3200U Shelves or be removed and reattached every time a CPS3200U shelf is added.
Note: There are two to airflow options provided for different applications: Airflow direction optimized for CO
deployments provided by the FTTN fan shelf is downward. Airflow direction for OSP applications is bottom to top. Baffles
should be oriented to direct cold air from the aisle through the converter shelf and out the back of the rack. A filter is
available and should be utilized in high contaminant areas with proper filter maintenance.

CPS3200U Upstream System – 23” Product Manual CPS3200U
Appendix A: Operating Temperature
Measurement and Vertical Spacing
Overview
The CPS3200U has been designed for mounting in relay racks or in equipment cabinets. It is designed for use with user
provided vertical airflow cooling of at least 175 linear feet per minute over the entire flow cross-section of the shelf.
Equipment may be placed on top of the CPS3200U provided airflow is not impeded or sufficient spacing is provided. A
1U Baffle is required above the highest converter shelf; this baffle provides sufficient vertical spacing. Direct the airflow
into a 3 inch minimum space. If the spacing is less than 3 inch spacing application specific testing is required.
Operating Temperature
The CPS3200U is rated to work to 65 C in stacks of two shelves in outdoor cabinets without baffles. Note: in outdoor
cabinets where the air entering the second shelf may be heated above 65C inlet temperature, additional airflow beyond
the 175 linear feet per minute is required. These cases require an engineered solution.
In Central Office environments when baffles are required for safety reasons, a three shelf system is rated to operate in
55C environments.
Baffles and Fan Trays
For Central Office applications, baffles are used between every set of three Converter shelves. Fan Shelves are required
for every set of three Converter shelves. No more than 6 shelves may be located in a particular frame. Slot covers must
be used on all empty slots when more than one shelf is being cooled by a particular airflow device.
Always mount converter shelves above the fan tray that cools them.
When mounting fan trays with converter shelves, leave no space between the top of a fan tray and the converter shelf
above it. The QS930A Fan Shelf draws air down through whatever equipment is located directly above it. If a gap is left
above a fan tray, air will be drawn into the fan tray from the aisles rather than from the converter shelf above the fan
tray. This will result in service effecting problems due to insufficient cooling air flowing through the active converters.
The QS931A Fan Shelf forces air up through whatever equipment is located directly above it. If a gap is left above a fan
tray, air will escape into the aisles rather than flowing into the converter shelf above the fan tray. This will result in
service effecting problems due to insufficient cooling air flowing through the active converters.
When mounting converter shelves always mount a converter shelf immediately above a fan shelf, or above a converter
shelf stacked on a fan shelf. Any gaps between converter shelves, or absence of slot covers, can cause service effecting
problems.
Note: All unpopulated converter slots must be filled with slot fillers. For example the figure below shows a shelf with
operational converters in the first two slots and slot fillers in the remaining 14 slots:

CPS3200U Shelf Alarm Card State Table
This section shows Alarm and LED response for the Alarm Card LEDs and Relays.
The CPS3200U shelf contains a pair of A bus feeds and a pair of B bus feeds. The use of dual A and B feeds is to not
exceed the 48 AMPS L2 input current per feed. The A bus feeds are designated A
(left side) and 9-16 (right side) respectively. The B bus feeds are also designated in an identical fashion. The alarm card
monitors the -48v on each of these four feeds, and asserts alarms and indicators as follows:

Alarm Relay: E – Energized relay in non-alarm state; D – De-energized relay in alarm state
Alarm Card Logical Operation of LEDs and Alarm Relays
The Alarm Card contains a pair of form C relays to provide shelf PMN and PMJ isolated closures. The relays are
energized, from both the A & B input bus, in their non-alarmed state, such that these relays will revert to the alarm state
if both A and B input fail. The relay circuit interfaces to a pair of parallel buses connected to each of the 16
Converter/Limiter Cards. Each Converter has an open collector output on the bus, and pulls the bus low to chassis
ground when it is asserting an alarm. The PMN/PMJ circuit on the Alarm card recognizes the bus state change and
denergizes the relay. The alarm card separately monitors both the PNM and PMJ bus. When the PMN bus is active
(pulled low), the Alarm card asserts a PMN relay and lights the ALM LED Yellow. When the PMJ bus is active (pulled low),
the Alarm card asserts a PMJ relay and lights the ALM LED Red. While an active PMJ is present the Alarm Card ignores
the state of the PMN bus (and does not assert a PNM relay/LED action). This IS necessary since the same LED is used for
both Minor (Yellow) and Major (Red) visual indication.
The Alarm Card also monitors the -48V dc inputs and asserts PNM/PMJ for conditions as described in the earlier section
dealing with input voltage monitoring.
The Alarm Card also monitors the two fan tray alarms. When either of the two fan tray alarms is active, the Alarm Card
asserts a PMN relay and Yellow ALM LED. When both of the fan tray alarms are active, the Alarm Card shall assert a PMJ
relay and Red ALM LED.

Revision History
Issue Comments
9 2013 December Corrected typos, restored Specification of Output Voltage, added weights for fan shelf and baffle,
updated figures showing converter shelf output side, updated figures showing baffle and filter holder installation,
and added section for Maintenance – Filter Cleaning.
8 2013 July Rebranding, minor reformatting, and minor updates.
7 2008 January Rebranding.
6 2007 December Clarifications: Page 5, added ‘converter shelf’ after GR487. Page 9, Dissipation clarifications. Page
10, Listed specific protector. Page 13, The return conductor of the -48V shall be terminated in the ground window,
(held at frame ground potential). Page 13, The telecommunication line cable, carrying the +/-190V between the
equipment and the primary protectors, shall be minimum 26 AWG, and rated minimum 200V. Page 13, Airflow must
be provided at a rate of 175 lfm across the entire cross section of the shelf for operation in environments up to 65 C,
when measured at the inlet of the warmest converter shelf. Page 13, For multi-shelf systems (up to 3), this equipment
has been evaluated for continuous use in ambient temperature from -40°C to 50°C when used with the QS982A
converters. Page 28, added: Otherwise all alarm cards should be left in their factory default state of address 0,0. Skip
this step if no QS941 will be present in the system. Page 28, added text and changed picture to show angle required
to remove alarm card. Page 38, Measurement from the exterior of the CPS3200U shelf to the cabinet or building
ground bus should indicate a resistance of less than 10 Ohms. Page 56, cleaned up some of the tense grammatical
errors.
Changes: Pages 7 and 9: L1 and 2 currents. Page 13, changed J1 to TB1. Page 49, Step 12 “J6” changed to “P6.”
Page 65, changed outdoor applications to 2 shelf system configurations between fan shelves. The operating
temperature section now reads:
The CPS3200U is rated to work to 65 C in stacks of two shelves in outdoor cabinets without baffles. Note: in outdoor
cabinets where the air entering the second shelf may be heated above 65C inlet temperature, additional airflow
beyond the 175 linear feet per minute is required. These cases require an engineered solution.
In Central Office environments when baffles are required for safety reasons, a three shelf system is rated to operate
in 55C environments.
5 2007 March References to multi-shelf configurations removed. Network inspection added.
4 2006 September Added transitional statements to improve flow. Added note on grounding practice for best EMI
performance to output connector pin out description. Added Ethernet present confirmation procedure.
3 2006 June Removed -190V items including rear access converter shelf. Clarified sections to support
downward airflow as standard configuration for fan tray. Corrected drawings.
2 Reformatted sections. Corrected shelf depth in reference information.
1 Draft with focus on installing Bulk fed shelves. Pictures added.
