1 • Introduction
Product features and benefits
Thank you for purchasing Patton Electronics Co. Model 6276 ForeFront Half-Pipe Chassis with CPCI 2U
backplane/midplane. The Model 6276 FireFront Half-Pipe Chassis is a modular 2U x 19 inch rackmount subrack-type CPCI packaging system.
The product offers a low cost, turnkey solution for customers desiring four 6U x 160mm slots in the least possible vertical rack space. The superior design also provides up to two power supply modules configured for
external DC or AC power input.
The rear of the chassis provides four 2U x 80mm slots for CPCI transition modules. Cooling is provided by
the specially designed plug-in fan tray module.
The Model 6276 ForeFront Half-Pipe Chassis complies with the PICMG 2.0 R3.0 CompactPCI Specification ,
and PICMG 2.5, ECTF H.110 (CT Bus) Specification (Rev. 1.0), making it an excellent choice for redundant,
fault tolerant applications.
What is CompactPCI?
CompactPCI (Compact Peripheral Component Interconnect) is a high-performance industrial computer platform based on the standard PCI electrical specification in rugged 3U or 2U Eurocard-style packaging, with a
high-quality 2mm metric pin and socket connector.
CompactPCI is an open specification supported by the PICMG (PCI Industrial Computer Manufacturers Group), which is a consortium of companies involved in utilizing PCI for embedded
applications.
Distinct advantages of CompactPCI (“CPCI”) include:
• Cost/time savings—Because it is electrically compatible with PCI, CPCI allows designers to tap into the
wealth of available hardware and software. CPCI provides a substantial reduction in engineering and manufacturing costs because off-the-shelf items can be shipped to meet your configuration needs and delivery
schedules.
• Rugged and reliable—The Eurocard-style packaging—which includes two-piece shielded connectors for
better reliability and vertical card orientation for better cooling—provides a robust system based on a subrack backplane architecture.
• Flexibility—CPCI allows either 32- or 64-bit PCI, plus offers an open architecture. Additional connectors
are defined for adding standard or proprietary buses or other needs. Hybrid CPCI systems allow bridging to
other buses or custom applications.
• Hot-swap capability—Boards can be hot-swapped without disrupting operation, a critical feature in real-
time and high-availability applications.
CompactPCI is rapidly becoming the backbone of today’s high-performance, embedded systems. It is ideally
suited for telecommunications, computer telephony, real-time machine control, industrial automation, realtime data acquisition, instrumentation, military systems and other applications requiring high speed computing and modular, robust packaging design.

Figure 3. Front view of chassis
Description of chassis rear side
The rear of the chassis is divided into two areas:
• A set of four 6U slots for ForeFront transition modules (see figure 2 on page 17). These modules typically con-
tain cable connections for I/O interfaces such as T1/E1 trunks, optical fiber trunks, DSL lines, Ethernet, etc.
• A set of 3U slots allocated for the following uses (see figure 4 on page 19):
- Power input module—either Patton Model 6112 (DC) or Patton Model 6117 (AC) (see figure 5 on
page 19). These modules provide power input to the power supplies in the front of the chassis (see
figure 2 on page 17). The input module provides input for both power supplies.
- Model 6103 Alarm Card (optional)—provides contact closure alarm relay outputs for external alarm
monitoring,

Electromagnetic compatibility (EMC)
The Model 6276 ForeFront Half-Pipe is designed to provide the highest levels EMC performance—in terms of
both interference and susceptibility. The chassis has the following design features to mitigate the effects of electromagnetic interference (EMI):
• All gaskets, contacts, and contact surfaces are electrically conductive.
• The mating surfaces of the EMC chassis and the EMC plug-in unit front panels and/or optional EMC filler
panels are also conductive by use of gaskets/strips.
• All chassis and plug-in contact surfaces are connected to a common chassis ground.
Electromagnetic compatibility (EMC) 19
Model 6276 User Guide 2 • Chassis specifications
Mating EMC gaskets and strips are used on the chassis, front panels of boards, and optional filler panels. An
EMC gasket is attached to the bottom of the chassis (front view), and an EMC strip is attached to the top.
Plug-in boards have the corresponding mates on the opposite side (see figure 6).
Figure 6. EMC strip and gasket on chassis and cards
The EMC strip on the left side of the board mates with the EMC gasket attached to the chassis when it is
plugged into the first slot. Each board mates together with corresponding gaskets/strips.
In addition, all metal components of the subrack are surface treated and conductive. Top, bottom, sides and
rear EMC covers provide mechanical protection and EMC shielding on the subrack. Retaining clips ensure
conductive connection.
The chassis contains an optional frame ground to signal ground jumper. By default, in all ForeFront Half-Pipe
products, this jumper is not installed. This means that frame ground (the electrical potential of the chassis shell
itself and all panels, screws, etc. that are connected to it) is electrically isolated from the signal ground (the electrical potential corresponding to “0 volts” with respect to the power supplies and cards in the chassis). Patton
Electronics recommends that this isolation be maintained, in order to improve the EMC characteristics of the
system and the integrity of the two distinct grounds.
See the chapter on installation and maintenance for further information on the jumper settings.
Electrostatic discharge (ESD) protection
The 6276 ForeFront Half-Pipe chassis provides ESD protection in compliance with IEEE 1101.10. ESD contacts are embedded inside and in the front section of card guides for making early as possible contact with a
discharge strip on one or both, the upper and/or lower edge of the plug-in board/module. Only one card guide
per slot (both front and rear) contain ESD clips. The ESD clip in the card guide is connected to the chassis
GND (ground).

Model 6276 User Guide 3 • System architecture
CompactPCI form factor
CompactPCI is flexible in the mechanical and connector area, using a passive backplane and plug-in daughterboards. The architecture is based on the IEC 1101.10 and 1101.11 Eurocard standard for the fixed 160mm
depth (for front boards), but allows for two board heights:
• 3U—100 mm high
• 2U—233.35 mm high
This variety enables a wider variety of applications and industries. 3U, which is the minimum for CompactPCI
as it accommodates the full 64-bit CompactPCI bus, is popular for embedded industrial automation applications, while 2U provides additional board real estate for more complex applications. 2U also provides more
connectors for rear-panel I/O often needed in telecom products.
Eurocard boards offer a long list of advantages:
• Extensive board keying capabilities so that boards can only be plugged into appropriate slots
• Card guides for solid rear backplane connectors alignment
• Injector/ejector handles
• EMC compliance that minimizes electromagnetic interference
CompactPCI boards are inserted at the front of the chassis—which provides maximum configuration flexibility—with options for I/O connections to either the front and/or rear of the card. The cards are firmly held in
position by their connector, card guides on both sides, and a face plate which solidly screws into the card cage.
CompactPCI form factor 26
Model 6276 User Guide 3 • System architecture
Board front panels
CompactPCI boards provide a front panel interface that is consistent with Eurocard packaging and compliant
with IEEE 1101.10 (EMC panels). Ejector/injector handles are used on the boards
(see figure 9). Filler panels
do not require handles.
Figure 9. Front panel—6U front-entry card
Transition boards
There are two types of boards:
• Front-entry boards (described in section “Board front panels” on page 27)
• Rear-entry boards for rear-panel I/O
The front-entry boards may route I/O through the backplane. Backplanes that enable rear I/O are called often
midplanes because the legs of the backplane connector’s pins stick through the board to become pins for rear-

Model 6276 User Guide 3 • System architecture
panel interconnections. An illustration of the front-entry board and rear-panel I/O board interface with the
backplane/midplane is shown in figure 10.
Figure 10. Front/rear boards and backplane interface
Rear-panel I/O boards are either 3U or 6U in width and are typically 80mm in depth. Other depths are
allowed depending on the application requirements. The 2U chassis provides an 80mm transition module section. This section provides four 6U x 80mm slots for cPCI transition modules.
All front-entry board features (handles, keying, alignment pin, EMC, etc.) are also utilized on the rear-entry
boards. The rear-panel I/O transition boards are “in-line” with the front-entry boards. This means that the
front panels of rear-panel I/O transition boards are reversed (mirrored) from the front boards. The top handles
are on the bottom and vice versa. The slot keying holes and hole labels in both the card guides and front panels
are upside down compared to the front boards and card guides.
The same connector pin labeling sequence is used on the rear I/O transition boards as on the front boards,
with the position numbers going from bottom to top. This is a mirror image of the front board’s layout orientation. Using the same 1-for-1 pin mapping sequence eliminates confusion and I/O signal pin mapping problems. For example, pin A3 is the same on the front boards, on the rear I/O transition board, and on the
backplane.
CompactPCI form factor 28
Model 6276 User Guide 3 • System architecture
Rear-panel I/O transition boards may have active components in some applications. Power can be applied
either through the I/O pins from the front board, or from the normal power and ground pins defined as part of
the J1/P1 and J2/P2 connector pin assignments.
Pin and socket connectors
The connection between boards and backplane is through a two-piece, 2 mm connector. Backplanes use male
(pin) connectors and plug-in boards use female (socket) connectors. This pin and socket connector offers
greater reliability, particularly when subject to shock, vibration, or temperature variations.
These pin and socket connectors provide:
• Faster propagation times
• Reduced reflection at the bus/connector interface
• Lower noise
• Better impedance matching
• Higher mechanical stability
The connector is a 235-pin device, arranged in 47 rows of 5 pins, with a total of 220 pins (15 pins are lost to
the keying area). The connector is shielded and devotes a large number of pins to ground. This reduces reflections, increases EMI immunity in noisy environments, and reduces ground bounce.
The fixed or male connector on the backplane is numbered P1-P5, starting at the bottom. The corresponding
female connectors are also numbered from the bottom up as follows:
• 6U cards—J1-J5 (see figure 11)
Figure 11. J1 through J5 connectors on the 6U card
Pin and socket connectors 29
Model 6276 User Guide 3 • System architecture
3U and 6U cards use a single 220 pin connector for all power, ground, and all 32- and 64-bit PCI signals. This
connector consists of two halves—the lower half (110 pins) is called J1/P1 and the upper half (also 110 pins) is
called J2/P2. Twenty pins are reserved for future use. The connector is divided in J1/P1, a 25-row connector
that includes voltage keying, and J2/P2, a 22-row connector without keying. The 2U card can have up to four
additional connectors with a total of 315 pins, which can be used for a variety of purposes.
A system CPU uses J1 and J2, but 32-bit peripherals cards only need to use J1 for full CompactPCI functionality. J3 through J5 on 2U cards can be user-defined I/O. Optional buses, such as the CT H.110 bus, use the
J4 position.
J1/P1 & J2/P2 connectors
The CompactPCI bus spans the J1/P1 & J2/P2 connectors, with 32-bit PCI implemented on J1/P1 and full
64-bit PCI implemented on J2/P2 on the Model 6276 Midplane. J1/P1 is always devoted to 32-bit PCI in
CompactPCI systems, however, use of J2/P2 for 64-bit PCI can be optional. For instance, J2/P2 may be
defined for user I/O, or sub-buses like the CT H.110 bus. J2 is always used on system slot boards to provide
arbitration and clock signals for peripheral boards.
J3/P3 through J5/P5 connector
J3/P3 through J5/P5 connectors, available only in 2U systems, are generally defined for user I/O. However,
sub-bus interconnects (for example, CT H.110 bus) can be configured on the J4/P4 connector.
Reserved pins
There are bused and non-bused reserved pins as noted below:
• The BRSVPxxx signals SHALL be bused between connectors and are reserved for future CompactPCI def-
inition.
• The RSV signals are non-bused signals that shall be reserved for future CompactPCI definition.
Power pins
The 2U Model 6276 Backplane/Midplane has a selectable signaling environment. All connectors on the 2U
Model 6276 Backplane/Midplane provide pins for +5V, +3.3V, +12V and -12V operating power. In addition,
there are power pins labeled +V(I/O). The V(I/O) power pins on the connector are used to power the buffers
on the peripheral boards, allowing a card to be designed to work in either interface.
In a ForeFront environment, the V(I/O) pins must always be configured for 3.3 VDC. This is selected by a
strap on the mid-plane.
Backplane architecture
Patton Electronics Company, 2U Model 6276 Backplane/Midplane provides one CompactPCI bus segment.
The cPCI bus segment is composed of four 6U board locations (at 33 MHz) with 20.32 mm (0.8 inch) board
center-to-center spacing. The 6U cards are stacked horizontally in the 2U model, however, the special design provides vertical convection cooling with the installed plug-in fan tray module (See Fan Tray Assembly on page 22).
Backplane architecture 30
Model 6276 User Guide 3 • System architecture
There are also two 3U x 160mm slots on the front right side, called the “Power Bay”, to mount Patton Power
Supply Modules configured for external DC or AC power input.
A rear view of the 2U Model 6276 is shown in figure 12.
Figure 12. Rear view of chassis showing the midplane/backplane
There are two user-configurable straps and a DIP switch located in the rear 3U area of the chassis.
• VIO signaling—This strap (using J1, J2, J3) sets the V I/O signaling voltage to 3.3 or 5 VDC. For all
ForeFront applications, this should be set to 3.3v. Do not change it from this setting.
• Frame ground/signal ground—This strap (using J4, J5) allows the user to electrically connect frame
ground (FG) to signal ground (SG). By default, these signals are electrically isolated. Patton Electronics rec-

ommends that this configuration be maintained. However, in certain specific circumstances, users may wish
to connect these two potentials by installing a jumper between J4 and J5.
• Shelf Geographic Address (SGA)—S1 has a DIP switch that enables the user to configure the shelf enu-
meration feature, used for multi-shelf CompactPCI systems. The SGA effectively becomes a chassis identification code, which is used to uniquely identify the chassis in a multi-chassis environment. This is
currently not used in most ForeFront applications, as most cards/devices are uniquely identified by an IP
address, which is manually configured for each device in the system.
Slot designation
Consistent with CompactPCI specifications, the cPCI bus segment consists of one system slot, and three
peripheral slots. The system slot is located in the first slot, or bottom slot in the 2U model.
The system slot provides arbitration, clock distribution, and reset functions for all boards on the segment. The
system slot performs system initalization by managing each local board’s IDSEL signal. The peripheral slots
may contain simple boards, intelligent slaves, or PCI bus masters.
CompactPCI defines slot numbering based on the concept of physical and logical slots. Physical backplane
slots are designated 1, 2, 3, through N, where N is the number of slots. Physical slot numbering starts at the
bottom slot on the 2U Model 6276 Backplane/Midplane.
Logical slot numbers are defined by the IDSEL signal and associated address used to select the slot. Logical
numbers are used in the nomenclature to define the physical outline of a connector on a bus segment. Logical
and physical slot numbers may not always coincide.
Backplane power distribution
Power is distributed in a CompactPCI system via the backplane. The backplane provides standard direct current (DC) supply voltages as specified in table 5 below:
Table 5. Power specifications
Mnemonic Description Nominal Value Tolerance
5 V +5 VDC 5.0 V ±5%
3.3 V +3.3 VDC 3.3 V ±5%

create a safety hazard. The double ground lug meets NEBS and will accept Amp part
# 606209-1. NEBS requires a double lug on DC chassis to ensure that the ground
connection will not rotate and become loose.
The dual frame ground lugs on DC interfaces must be used to connect the chassis to earth ground. Failure to do this will cause excessive RF emissions and
could possibly create a safety hazard.
WARNING
Front panel keying for power supplies
Power supply keying options have been registered with PICMG. Since power supplies use a different type of
connector than other CompactPCI slots, there is no possibility of mating problems with 2mm connectors. The
power supply key options are independent of the 2mm application card keys, and may duplicate key codes that
are used for different purposes elsewhere in the system.
Specific front panel keying is defined to prevent damaging an AC power supply inserted into a backplane wired
for DC and vice versa.
Hot-swap capability
Hot-swapping is the capability of removing and replacing components without turning off the system. Hot-swap
capability is becoming increasingly important in systems requiring continuous operation at some level. Because
boot times of many popular operating systems are long, the hot-swap capability is crucial for high-end PC servers,
and even more so for telecommunication systems, such as base stations, where board-level exchanges must be
made without any downtime. CompactPCI supports dynamic configuration to allow hot removal/insertion of
boards without interrupting backplane transactions or disturbing DC voltages in the power system.
The hot-swap feature is implemented on the CPCI boards, not on the backplane. The backplane remains passive. Therefore, CompactPCI boards either are or are not hot-swappable.
Signal lines must be precharged to 1V before being plugged into the backplane to maintain ongoing bus transactions. Also, power must be ramped up or down in a controlled manner to allow the power supply to adjust to
Hot-swap capability 33
Model 6276 User Guide 3 • System architecture
the change in load. The power supply, ground and signal pins on the connectors are staged to allow sequencing, so as to not disturb the operation of the surrounding boards in the bus. The three levels of sequencing are:
• Short pins for BD_SEL#
• Medium pins for signals
• Long pins for power/ground
The system uses two levels of sequencing so that power/ground is made first/broken last. The short pin
(BD_SEL#) connection is made only when the board is firmly seated, which signals the control circuitry to
power up any high-current devices. Conversely, BD_SEL# breaks first to provide early warning to the
control circuitry.

The Model 6276 Mid-plane & Chassis can be easily configured according to your system requirements. Due to
the broad application possibilities, the following checklist is provided as a quick set-up guideline.
1. Connect frame ground/signal ground (FG/SG)—You may opt to connect the FG/SG for EMC consider-
ations and noise reduction, via power lugs, located at the rear, right-side of the backplane. This is an
optional configuration that is not recommended for most users; the factory default is “no connect”.
2. Assign shelf address—For multi-shelf systems, each sub-rack bus segment can be assigned a shelf address
via the S1 header, located at the rear, left-side of the backplane.
3. Install 2U chassis on rack—the chassis front mounting flanges should be securely fastened to the rack
with screws.
4. Install power supply modules—For N+1 power operation, install up to two Patton power supply modules
at the front of the chassis.
5. Install cards—Plug the system application card(s) in the 6U slot(s) at the front of the 2U chassis. Plug
alarm card in the left-hand slot at the back of the chassis, and plug transition cards in remaining slots, if
needed.
The interconnecting cables shall be acceptable for external use
and shall be rated for the proper application with respect to voltage, current, anticipated temperature, flammability, and

Power cable installation
This section describes installing the power and ground cables.
Installing the power cables—AC unit
This section describes installing the power cables into the IEC-320 connectors on the Model 6276 power supply. Do not connect the remaining end of the power cables to the power outlet at this time. Do the following:
1. Install a power cable into an IEC-320 connector (see figure 13). The AC main socket outlet shall be within
3 meters of the equipment and shall be easily accessible.
Figure 13. IEC-320 connector and grounding stud locations
To avoid the risk of injury from electric shock, the power cords connected to
the IEC-320 connectors must be grounded power cords.
WARNING
2. Rotate the power cable retainer clip (see figure 13) so it secures the power cable plug in the
IEC-320 connector.
Installing the power cables—DC unit
This section describes installing the power cables into the DC power input module. Do not connect the
remaining end of the power cables to the DC power source at this time. The Model 6276 DC power supply
module comes with two power input terminal blocks (J1 and J2). The Model 6276 can draw power from
sources connected to either of these terminal blocks (inputs are diode-ORed and combined to provide for
redundant power input). Although the power supply module is designed to operate normally with one power
source, users may want to connect two independent power sources, one to each terminal block, to provide
uninterrupted operation in the event of one source failure.
Use AWG 18 copper conductors for the DC supply.
CAUTION
1. Connect the earth ground of the DC source to the grounding stud on the Model 6276 chassis as described
in section “Grounding the Model 6276—AC and DC units” on page 38.

2. Strip back the insulation on each of the supply wires approximately 1/4 inch.
3. Insert the stripped end of the positive lead into the “+DC input” of the terminal block. Tighten the screw
until the power lead is firmly fastened. Repeat the procedure for the negative lead, using the “-DC input”
of the terminal block. Make sure that there is no exposed wire.
Figure 14. DC connector, -DC and +DC input view
4. Repeat steps 1 through 3 to install the remaining DC power connection.
Grounding the Model 6276—AC and DC units
Do the following:
1. Assemble a ground wire using #10 AWG wire with green-colored insulation and two ring terminals. Make
the wire long enough to reach one of the following ground sources:
– The building ground rod (generally located at the site’s main service entrance)
– A sprinkler system pipe
– A cold-water pipe
– Building structural steel
To avoid the risk of personal injury, the distance between ground and the
equipment rack must not exceed the distance specified in either local electrical
codes or the National Electrical Code.
WARNING
2. Install the ground wire between the grounding studs (see figure 13 on page 37 for AC power entry, or
figure 14 on page 38 for DC power entry) and the grounding source.
Changing the VI/O configuration jumper
The Model 6276 VI/O is factory configured for 3.3V, do not change this setting when using ForeFront cards.
Optional frame ground/signal ground connect
There are two headers, J1 and J2, located in the power bay area. J1 corresponds to signal ground (SG) and J2
corresponds to frame ground (FG). These two headers provide an option to connect FG and SG. The factory

Preventive maintenance
Clean fan filter
Periodically clean the filter on the Fan Tray Assembly. The frequency of cleaning depends on the environmental
conditions of where your equipment is located. Clean filter with a mild detergent and water, then air-dry, or
you can use compressed air. It should be completely dry before reuse.
Spare filters (part no. 05-00440-01) are available from Patton Electronics Company.
Note When replacing the air filter, note that it is directional—the air-flow direction
must be in the direction indicated by the arrows on the filter.
Troubleshooting
System won’t power up
If the green LED on the power supply module does not light up, you should remove it from the chassis (warmswap). Then plug it back in, making sure it is seated properly. If green LED still does not light up, check to
make sure the polarity is wired correctly at the back of the chassis.
If the green LED lights up on the power supply module, but the system still isn’t powering-up, then the module may be faulty and should be returned to the manufacturer.
No-load condition generates a false alarm
The power supply module may generate a false alarm under a no-load condition (no cards installed). A minimum of
1/2 amp (system admin card would suffice) needs to be plugged into the sub-rack to prevent this false alarm.
