Compliance Information
Radio
and TV
Interference
The Model 6676 ForeFront™ Xtreme™ Chassis generates and uses radio frequency energy, and if not
installed and used properly—that is, in strict accordance with the manufacturer’s instructions—may cause
interference to radio and television reception. The Model 6676 ForeFront Xtreme has been tested and found to
comply with the limits for a Class A computing device in accordance with the specifications in Subpart B of
Part 15 of FCC rules, which are designed to provide reasonable protection from such interference in a com-
mercial installation. However, there is no guarantee that interference will not occur in a particular installation.
If the Model 6676 ForeFront Xtreme Chassis causes interference to radio or television reception, which can be
determined by disconnecting the cables, try to correct the interference by one or more of the following mea-
sures: moving the computing equipment away from the receiver, re-orienting the receiving antenna, and/or
plugging the receiving equipment into a different AC outlet (such that the computing equipment and receiver
are on different branches).
Industry Canada Notice
The Canadian Department of Communications label identifies certified equipment. This certification means
that the equipment meets certain telecommunications network protective, operational and safety require-
ments. The Department does not guarantee the equipment will operate to the user's satisfaction. Before install-
ing this equipment, users should ensure that it is permissible to be connected to the facilities of the local
telecommunications company. The equipment must also be installed using an acceptable method of connec-
tion. In some cases, the company’s inside wiring associated with a single line individual service may be
extended by means of a certified connector assembly (telephone extension cord). The customer should be
aware that compliance with the above condition may not prevent degradation of service in some situations.
Repairs to some certified equipment should be made by an authorized maintenance facility designated by the
supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give
the telecommunications company cause to request the user to disconnect the equipment. Users should ensure
for their own protection that the ground connections of the power utility, telephone lines and internal metallic
water pipe system, are connected together. This protection may be particularly important in rural areas.
FCC Part 68 Compliance Statement
This equipment complies with Part 68 of the FCC rules and the requirements adopted by the ACTA. Refer to the plug-
in cards’ user guide for details.
CE Notice
The CE symbol on your Patton Electronics equipment indicates that it is in compliance with the Electromag-
netic Compatibility (EMC) directive and the Low Voltage Directive (LVD) of the European Union (EU). A
Certificate of Compliance is available by contacting Technical Support.
Users should not attempt to establish or modify ground connections
themselves, instead they should contact the appropriate electric
inspection authority or electrician.

Introduction
Thank you for purchasing Patton Electronics Co. Model 6676 ForeFront Xtreme Chassis (see figure 1). The
Model 6676 ForeFront Xtreme Chassis is a modular 9U x 19 inch rackmount subrack-type packaging system
adaptable to a wide array of product configurations.
ForeFront Xtreme Chassis features include:
•Fully compatible with all Patton ForeFront modules
•EMI shielding on entire assembly, with continuous chassis ground
•Lightweight and durable aluminum alloy construction, suitable for rugged environments
•Front mounting flanges for 19 in. rack mount environments
Figure 1. Model 6676
The ForeFront Xtreme Chassis offers a low cost, turnkey solution for customers desiring seventeen 6U x
160mm slots (two separate cPCI bus segments: one segment having 8 slots, the other 9 slots; only the power
and alarm buses are common to both cPCIs) in the least possible vertical rack space. The superior design also
accepts four 3U plug-in power supplies for N+1 redundancy. The power supplies are configured for external
DC power input.
The rear of the chassis provides four 6U x 80mm slots for transition modules. Cooling is provided by the spe-
cially designed model 6670-FT plug-in fan tray module.

14 Introduction
Description of chassis front side
There are 17 6U x 160mm slots at the front of the chassis (see figure 2). Front-entry ForeFront modules, in accor-
dance with PICMG 2.0 CompactPCI specifications, are plugged into these slots.
Figure 2. Model 6676 ForeFront Xtreme Chassis

Introduction 15
Model 6676 6U CPCI Chassis Assembly User Guide 1 • Introduction
The front of the chassis also provides four slots suitable for Model 6160 (DC) 3Ux8HP ForeFront power sup-
plies (see figure 2 on page 14). The Model 6160 power supply is described more completely in the Model 6160
and 6161 User Manual.
All slots provide 4HP module spacing and are on 0.80 in. centers (except for the power supply slots, which are
offset 0.1” as per PICMG 2.11 standard). Card guides are molded plastic with metallic ESD contacts per Com-
pactPCI PICMG 2.0 R3.0 & IEEE 1101.10 .

16 Introduction
Description of chassis rear side
The rear of the Model 6676 chassis provides seventeen 6U x 80mm slots for ForeFront rear transition modules
for rear-panel I/O (see figure 3). See section “ForeFront AIS blades” on page 20 for more information.

Introduction 17
Model 6676 6U CPCI Chassis Assembly User Guide 1 • Introduction
All slots provide 4HP module spacing and are on 0.80 in. centers. Card guides are molded plastic with metallic
ESD contacts at the bottom of the chassis per CompactPCI PICMG 2.0 R3.0 & IEEE 1101.10. Cardguides
provide keying and alignment in accordance with IEEE 1101.10, section 8.
Figure 5. DC rear power entry module (2 per Model 6676)
A set of 3U slots allocated for two Patton Model 6112/HOR (DC) rear power entry modules (see figure 5).
Electromagnetic compatibility (EMC)
The Model 6676 ForeFront Xtreme is designed to provide the highest level of EMC performance—in terms of
both interference and susceptibility. The chassis has the following design features to mitigate the effects of elec-
tromagnetic 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.

18 Introduction
Figure 6. EMC strip and gasket on chassis and cards
The EMC strip on the left side of the board (see figure 6) 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.
Note EMC gaskets/strips are in reverse order at the rear of the 6U chassis.
That is, the EMC strip is on the left of the chassis and the EMC gas-
ket is on the right. Consequently, rear transition boards are likewise
in reverse order to the front-entry boards. The EMC gasket is on the
left, and the EMC strip is on the right.
In addition, all aluminum and steel components of the subrack are surface treated and conductive. Top, bot-
tom, sides and rear EMC covers provide mechanical protection and EMC shielding on the subrack. Retaining
clips ensure conductive connection.
Electrostatic discharge (ESD) protection
The 6676 ForeFront Xtreme chassis provides ESD protection in compliance with IEEE 1101.10. ESD con-
tacts 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 the card guides
located at the bottom rail of the chassis (right vertical rail for the 6U chassis), both front and rear (when there
is a transition module present in the chassis), contain the ESD clips. The ESD clip in the card guide is con-
nected to the Chassis GND (ground).
