# 1.5.3 Backplane Thermal Sensors
# 1.5.4 PCI Express
Connector pin assignments of the PXI Express System Con- troller Slot, PXI Express Hybrid Peripheral Slots, and PXI Express Peripheral Slots comply with the default pin assignments as defined in PXI-5 PXI Express hardware specification Rev.1.1.
The PXES-2596 backplane provides a PCIe Gen3 switch fabric, allowing PCI express bus data streams between the system slot and all peripheral slots. The system slot supports up to PCIe 2-link x8 x8 Gen3 lanes, with all peripheral slots supporting up to PCIe x4 Gen3 links individually.
Figure 7: Backplane PCI Express Bus Topology
# PXI Express System Controller Slot
The System Controller slot is Slot 1 of the chassis as defined by the PXI specification. The PXES-2596 chassis can accommodate a PXI Express system controller that occupies width up to 4 slots. As defined in the PXI specification, three controller expansion slots allow the controller to expand to the left to pre-vent the controller from using up peripheral slots.
# PXI Express Hybrid Peripheral Slots
8 PXI Express hybrid peripheral slots are provided in the PXES-2596, all connected with PCIe x4 Gen3 lanes. Each can accommodate a 3U PXI Express CompactPCI Express / hybrid slot compatible PXI-1 Compact- PCI peripheral module.
# PXI Express Peripheral Slots(2596E)
3 PXI Express peripheral slots are provided in the PXES- 2596E, all slots connected with PCIe x4 Gen3 lanes. Each can only accommodate a 3U PXI Express Compact- PCI Express peripheral module.
Figure 8: 3U hybrid slot compatible PXI-1 peripheral module
Figure 9: 3U PXI Express peripheral module
# Local Bus
The local bus on a PXI backplane is a daisy-chained bus that connects each peripheral slot with adjacent peripheral slots to the left and right. The quantity of local bus lines is decreased from thirteen to one on a PXI Express backplane. The remaining local bus line can transmit analog or digital signals between modules.
# Trigger Bus
The trigger bus is an 8-line bus that connects all slots on the PXES-2596, providing inter-module synchronization. PXI and PXI Express modules can exchange trigger or clock signals through the trigger bus, allowing precisely timed response to asynchronous external events the system is monitoring or con- trolling.
# Reference Clock
The PXES-2596 backplane supplies single-ended 10MHz reference clock (PXI\_CLK10) and differential 100MHz clock (PXIe\_CLK100) to each peripheral slot for inter-module synchronization. The independent buffers drive the clock signal to each peripheral slot.
These common reference clock signals can synchronize multiple modules in a PXI Express chassis. PXI modules with phase-lock loop circuits can lock reference clocks to generate an in-phase time base.
The PXI\_CLK10 and PXIe\_CLK100 clocks are in-phase according to the PXI-5 specification. Since the external 10MHz clock input can override the onboard 10MHz clock source, a phase-lock loop (PLL) circuit on the backplane synchronizes the PXIe\_CLK100 and external 10MHz clock.
# 2 Getting Started
This chapter describes procedures for installing the PXES-2596 and making preparations for its operation. Please contact ADLINK or authorized dealer if there are any problems during the installation
# 2.1 Power Supply Budget Considerations
Please review the power consumption of all modules used in the same PXES-2596. The total maximum power consumed by the system module and peripheral modules shall not exceed the DC power supply of the PXES-2596 as defined in DC Power Output.
# 2.2 Cooling Considerations
The PXES-2596 features an innovative design for heat dissipation, with cooling fans in the rear section of the chassis, drawing cool air through apertures on the bottom for exhaust through the back. This design provides uniform airflow for each PXI slot and exceptional cooling capability. When the chassis is installed in a rack, the cooling design minimizes drawing of hot air from the rear area, where other devices exhaust, while maintaining a steady temperature inside the chassis. For optimal cooling efficiency, retain support feet.
When rack mounting the PXES-2596, at least 1U (44.5 mm/1.75 in.) clearance below the intake apertures is required. Also keep other objects or equipment at a minimum of 76.2 mm (3 in.) away from the outlet apertures in the rear region of the chassis.
# 2.3 Cooling Configurations
Heat ventilation is related to the installation location, environmental temperature, and total heat generated by the system module and peripherals. The PXES-2596 features a smart fan function to provide sufficient ventilation and minimize noise emission. There is a switch located at rear of the chassis to configure the smart fan operation.
Auto - Enables smart fan function.
High - Full fan rotation utilization.
# 2.4 Hardware Installation
# 2.4.1 Installing the System Controller
The PXES-2596 incorporates a system controller slot supporting a PXI Express system controller of 3 or 4 slot widths. We recommend the ADLINK PXIe-3987 Controller for use with the PXES-2596.
1. Ensure the CPU, memory module(s), and storage device(s) are properly installed on the system controller.
2. Locate the system controller slot (Slot 1).
3. Depress the system controller module’s latch to release.
4. Align the module’s top and bottom edges with the card guides, and carefully slide the module into the chassis.
5. Lift the latch until the module is securely seated in the chassis backplane.
6. Fasten the screws on the module front panel, and connect all devices to the system controller.
# 2.4.2 Installing Peripheral Modules
The PXE-2596 supports up to eight peripheral modules.
1. Select an available peripheral slot (2 to 9).
2. Depress the peripheral module’s latch and align the module’s top and bottom edges with the card guides.
3. Carefully slide the module into the chassis.
4. Lift the latch until the module is securely seated in the chassis backplane.
5. Fasten the screws on the module’s front panel.
6. Repeat steps 1 to 5 to install additional PXI peripheral modules.
# 2.5 Rack Mounting
ADLINK provides hardware for optional installation of the PXES- 2596 to a rack. When mounted in a rack, the Rack-Mount kit(G) (part number 91-95115-0010) allows for adjustable placement of the PXES-2596 further back in the rack, thus allowing ample room at the front of the unit for external mechanical parts (such as cables and mass interconnect modules).

# A.3 Maintenance
# 1. Handling the Chassis
The PXES-2596 is designed for both rack-mount and benchtop use. When transporting or carrying the chassis, it is recommended that the handle be used, being designed to support the weight of the chassis for superior portability and balance.
The PXES-2596 weights 11 kg. Please be careful when moving the chassis to avoid any possible injury.
# 2. Cleaning the Exterior
Make sure that the system is turned off before cleaning the chas- sis exterior. Wipe the exterior with a clean cloth starting from areas that easily accumulate dust or dirt such as the area in and around the chassis and power supply air intake apertures.
# 3. Power Requirements
Make sure that the power cord is in good condition before plugging it into the system. It is important to check the reliability of the power source. The PXES-2596 power supply is capable of han- dling 100 to 240 V AC within the 50 Hz to 60 Hz range. Do not connect the PXES-2596 to an already overloaded circuit.
