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 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.
Introduction 17
1 • Introduction Model 6676 6U CPCI Chassis Assembly User Guide
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 gasket 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, bottom, 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 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 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 connected to the Chassis GND (ground).
18 Introduction
Model 6676 6U CPCI Chassis Assembly User Guide 1 • Introduction
There is an alignment/ESD pin on the injector/ejector handle of boards (see figure 7).
Card handle
Alignment/ESD pin
Figure 7. Alignment/ESD pin on card handle
The alignment pin does the following:
• Ensures that the connectors are correctly aligned before they engage
• Provides solid/protected keying
• Provides board ESD contact
• Ensures that the EMC gasket is properly aligned (see “Electromagnetic compatibility (EMC)” on page 17)
• Ensures that when the board is inserted in the card guide, an integrated ESD clip discharges ESD from the
board to the right vertical rail chassis ground.
Hot-swap capability
Hot-swapping is the capability of removing and replacing components without turning off the system. Hotswap 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.

Figure 8. Front/rear modules and mid-plane interface
Mid-plane architecture
The mid-plane consists of two H.110 bus segments that support 17 6U slots (eight 6U modules for one segment
and nine 6U modules for the other). Both H.110 buses have 20.32 mm (0.8 inch) board center-to-center spacing.
The 6U cards are stacked vertically in the chassis. Power is distributed equally to the H.110 bus segments from
both power supplies.
In addition to the 17 6U slots, there are two 3U x 160 mm slots on the front right and two 3U x 160 slots on
the left of the ForeFront Xtreme Chassis. These slots support two Model 6160 or 6161 DC power supply modules (see figure 3 on page 15).

1. Install 9U chassis on rack—the chassis front mounting flanges should be securely fastened to the rack
with screws.
2. Connect chassis ground—The chassis must be grounded by #12 AWG ground wires attached to a reliable
grounding source.
3. Install power supply modules—For N+1 power operation, install up to four Patton power supply modules
at the front of the chassis.
4. Install modules—Plug the front-entry modules in the 6U slots at the front of the ForeFront Xtreme Chas-
sis. Plug the alarm card in the left-hand slot at the back of the chassis, and plug the rear-entry cards in
remaining slots, if needed.
5. Wire rear panel for power.
To avoid a potential shock hazard, connect the chassis ground before
connecting power.

Power cable installation
This section describes installing the DC power and ground cables.
.
Verify that the installation site is in compliance with the following
power requirements before installling the ForeFront Xtreme chassis:
• An approved external source must be rated a maximum of 72
VDC, 10 A and provide over current protection upstream of
the equipment.
• An approved disconnect device with a minimum 3.0 mm con-
tact separation must be provided upstream of the device and
rated at least 75 VDC, 7.0 A and be located so it is accessible to the operator.
• This equipment shall be connected directly to the DC supply
system bonding jumper from an earthing terminal bar or bus
to which the DC supply system earthing electrode is connected.
• This equipment shall be located in the same immediate area
as any other equipment that has a connection between the
earthed conductor of the same DC supply circuit and the
earthing conductor, and also the point of earthing of the DC
system. The DC system shall not be earthed elsewhere.
• There shall be no switching or disconnecting devices in the
earthed circuit conductor between the DC source and the
point of connection of the earthing electrode conductor.
Installing the power cables
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. Each DC power supply module
comes with two power input terminal blocks (J1 +/- and J2 +/-). The Model 6676 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.
Remove power plugs from all power inputs prior to servicing.
Use AWG 12 copper conductors to feed power to the DC supply.
1. Connect the earth ground of the DC source to the grounding stud on the DC power supply as described
in section “Grounding the Model 6676” on page 29.

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 + J1 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 -J1 DC input”
of the terminal block. Make sure that there is no exposed wire.
Figure 11. DC connector, -DC and +DC input view
4. Repeat steps 1 through 3 to install the remaining DC power connection on J2.
Grounding the Model 6676
Do the following:
1. Assemble a ground wire using #6 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)
– Central office isolated ground plane
– Central office isolated bonding network
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.

Preventive Maintenance
Cleaning the fan filter
Periodically clean the filter on the Fan Tray Assembly (see figure 2 on page 18). 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. 6670-AF-6) are available from Patton Electronics Company.
Troubleshooting
System won’t power up
If the green LED on the power supply module does not light up, you should: remove the power supply module
from the chassis, then plug it back in, making sure it is seated properly. If the green LED still does not illuminae, verify that 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.
