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 sub- rack-type CPCI packaging system. The product offers a low cost, turnkey solution for customers desiring four 6U x 160mm slots in the least pos- sible vertical rack space.
ForeFront CompactPCI open bus architecture. The rugged, rack-mounted chassis system is ideal for carrier-class, defense, industrial, enterprise, and commercial environments. The 6276 excels in its ease of access, superior cooling, and power distribution. The base unit is adapt- able to a wide array of product configurations.
There are four 6U x 160mm slots (a full CPCI bus segment) at the front of the chassis (see figure 2). Front- entry ForeFront modules, in accordance with PICMG 2.0 R2.1 CompactPCI specifications, are plugged into these slots. Figure 2. Model 6276 ForeFront Half-Pipe Chassis Description of chassis front side...
Model 6276 User Guide 2 • Chassis specifications The front of the chassis also provides two slots suitable for 3Ux8HP ForeFront power supplies, model 6160 (DC) or 6165 (AC). These devices are described more completely in the 6160/6165 Users Manual.
Figure 5. AC and DC rear power entry modules 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 elec- tromagnetic interference (EMI): •...
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 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.

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 daughter- boards. 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: •...
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).
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 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.
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.
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.
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 Figure 12.
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.
Model 6276 User Guide 3 • System architecture External power connections The chassis provides a rear DC interface panel with -48 VDC power interfaces for N+1 power operation and dual ground lugs, as shown in figure 5 on page 19. The connectors are described in table Table 6.

4 • Installation checklist 2U quick set-up checklist 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 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).
