# 1 Introduction

The ADLINK PXES-2780 18-slot PXI Express chassis is compliant with PXI Express and cPCI Express specifications, and offers one system slot, one system timing slot, six PXIe peripheral slots, and ten hybrid peripheral slots for versatile testing and measurement applications requiring enhanced bandwidth. The hybrid-slot design accepts installation of CompactPCI, PXI, CompactPCI Express, and PXI Express modules into any peripheral slot, maximizing flexibility. The PXES-2780 provides a configurable PCIe switch fabric and is configurable in two-link and four-link PXI express deployments, with 8GB/s system bandwidth and up to 4GB/s slot bandwidth for dedicated peripheral slots, thanks to second generation PCIe signaling technology.

The PXES-2780 implements a smart system monitoring controller, reporting full chassis status, including fan speed, system voltages, and internal temperature.

Equipped with an industrial grade AC power supply, the PXES-2780 delivers 800W of power in environments from 0°C to 55°C, and features an innovative cooling scheme providing superior heat dissipation. Three 185.9CFM fans in the rear section of the chassis draw cool air from apertures on the bottom and front of the chassis, over the PXI/PXIe modules, to be exhausted to the rear. This innovative cooling design provides, not only exceptional efficiency of heat dissipation, but also superior uniformity for each PXI slot. BNC connectors for 10 MHz clock input/output on the rear panel increase chassis flexibility, enabling synchronization with supplementary devices.

# PCI Express Link Capability

The PXES-2780 backplane provides a configurable PCIe switch fabric, allowing PCI express link configuration between system slot and PCIe switch fabric to change from 4-link x 4 lanes (factory default) to 2-link x 8 lanes.

4-link x 4 lanes configuration delivers the most balanced PCI express topology, with all the peripheral slots sharing equally in system bandwidth.

2-link is installed into PCIe x8 peripheral slots, providing the module with the highest throughput. For more details, please see “PXIe Link” on page 35.

NOTE:

Connector pin assignments of the PXI Express System Controller Slot, PXI Express System Timing 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.1.0.

# PXI Express System Controller Slot

The System Controller slot is Slot 1 of the chassis as defined by the PXI specification. The PXES-2780 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 prevent the controller from using up peripheral slots.

# PXI Express System Timing Slot

The System Timing (ST) slot is Slot 10, providing one dedicated single-ended star trigger and 3 pairs of differential star trigger lines to each peripheral slot. Routing of single ended star trigger signals (PXI\_STAR) and differential star trigger signals (PXIe\_DSTAR) are as follows.

# 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

Three trigger bus segments on the PXES-2780 consist of a first segment from 1st to 6th slots, a second from 7th to 12th slots, and a third from 13th to 18th slots, with each trigger bus segment containing 8 trigger lines connecting all slots on the same segment, 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. Two trigger bus buffers can connect or disconnect the trigger lines of adjacent segments.

As shown, eight combinations of trigger bus segment connections are possible between the three bus segments, with any applicable to each of the eight trigger lines.

# Reference Clock

The PXES-2780 backplane supplies a 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 timebase.

The PXI\_CLK10 and PXIe\_CLK100 clocks are in-phase according to the PXI™ 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.

The PXES-2780 PXI chassis automatically selects the 10 MHz reference clock source from among:

 Built-in accurate 10 MHz clock source
 External 10 MHz clock through a BNC connector
 PXI\_CLK10\_IN pin on the system timing slot

Priority of the 10MHz reference clock is as follows.

<table><tr><td>System Timing Slot (10th slot)</td><td>BNC Connector on Rear Panel</td><td>10mhz Clock Driven to Peripheral Slots</td></tr><tr><td>No clock present</td><td>No clock present</td><td>10MHz clock is generated by backplane</td></tr><tr><td>No clock present</td><td>10MHz clock present</td><td>Clock from BNC connector is driven to all peripheral slots</td></tr><tr><td>10MHz clock present</td><td>No clock present</td><td>Clock from system timing slot is driven to all peripheral slots</td></tr><tr><td>10MHz clock present</td><td>10MHz clock present</td><td>Clock from system timing slot is driven to all peripheral slots</td></tr></table>

# 2.2 Cooling Considerations

The PXES-2780 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-2780, 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.

![The image shows a simple icon of a white document or piece of paper with the top-right corner folded down. Faint grey horizontal lines appear on the lower portion of the paper, resembling a list. A large, thick red checkmark is drawn over the center of the document, extending from the bottom left to the top right.](.pxes-2780-50-17043-1010-22/08bda936e7924742863e3ac91241fca5fbd910dc0fd8bf30f83115ce3c72ca1b.jpg)

# 3 System Management & Configuration

The PXES-2780 chassis provides advanced system monitoring and control. Chassis conditions, including internal temperature, fan speed, and DC voltage can all be monitored on the system controller or remote PC.

The PXES-2780 provides software configurable trigger bus bridges, whereby the user can set the status of each trigger bus line as shown in Figure 1-13. The PXES-2780 backplane can also be configured between 4-link x 4 lanes or 2-link x 8 lanes by the configurable PCIe switch fabric.

Communication with the chassis monitoring control unit is available using an embedded controller, such as the ADLINK PXIe-3975, to access the SMBus located on the system slot (1st slot), or, alternatively, using a remote PC to communicate via the RS-232 serial port (D-SUB9 connector on the rear panel).

Please note that the RS-232 serial port can only monitor chassis status, but does not provide the capability to change the trigger bus bridges and PCIe switch fabric settings. Function comparison between the SMBus interface and RS-232 serial port is as follows.

<table><tr><td>Function</td><td>SMBus</td><td>RS-232 Serial Port</td></tr><tr><td>Chassis status monitoring</td><td>Yes</td><td>Yes</td></tr><tr><td>Alarm threshold setting</td><td>Yes</td><td>Yes</td></tr><tr><td>Trigger Bus setting</td><td>Yes</td><td>No</td></tr><tr><td>PXle link setting</td><td>Yes</td><td>No</td></tr></table>

When the Fan switch on the rear panel is set to AUTO, fans run at different speeds based on the measured temperature.

Target Temp indicates the temperature at which fans run at 100%. Using the default $5 0 ^ { \circ } \mathrm { C }$ as an example, fans run at 40% when all temperature readings are less than $\boldsymbol { 2 5 ^ { \circ } \mathrm { C } }$ , and begin rampup when any reading exceeds $\boldsymbol { 2 5 ^ { \circ } \mathrm { C } }$ .

Fans reach 100% speed if any temperature reading exceeds $5 0 ^ { \circ } \mathrm { C }$ (i.e. Target Temperature).

Setting parameters are as shown.

# Appendix A - Troubleshooting and Maintenance

This Appendix describes basic troubleshooting techniques, as well as instructions for the maintenance of the PXES-2780 chassis.

# A.1 Installation Problems

Inability to start the system frequently results from incorrect installation of the system controller, peripheral modules, and other components. Before starting the system, please ensure that:

 The system controller is properly installed and secured
 All peripheral modules are properly seated on the slots
 All cables are properly connected to the system controller and peripheral modules
 All installed peripheral modules are compatible for use in the chassis
 The power cord is securely plugged into the chassis power connector and power outlet/wall socket/power strip

If the system fails to start when all installation conditions are met, remove all installed peripheral modules and try again. If the system starts normally, install one peripheral module at a time followed by powering up. You may also try installing the modules into different slots until the desired result is obtained.

# A.2 Basic Troubleshooting

<table><tr><td>Problem</td><td>Ensure that:</td></tr><tr><td>System fails to power up</td><td>► The power cord is securely plugged into the chassis power connector and wall socket/power strip► The wall socket/power strip is live► The power button on the chassis front panel is activated</td></tr><tr><td>No video output in the external display</td><td>► The external display is functioning properly► Display settings support external video.</td></tr><tr><td>Power LED (blue) is blinking</td><td>► There is no short circuit by removing all PXI modules (PXI controller and peripheral modules)If the signal persists, contact your dealer for further assistance</td></tr><tr><td>Fan LED (green) is blinking</td><td>► The fan is unobstructedIf the signal persists, contact your dealer for further assistance.</td></tr><tr><td>Temperature LED (amber) is blinking</td><td>► Airflow from the outlet apertures is unobstructed and steady; if not, ensure that adequate clearance for the intake apertures is providedIf the temperature of exhausted air is normal (70°C in Default setting) but the temperature LED is still blinking, contact your dealer for further assistance.</td></tr></table>

# A.3 Maintenance

# A.3.1 Handling the Chassis

The PXES-2780 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-2780 weights 11.9 kg (26.2 lb). Please be careful when moving the chassis to avoid any possible injury.

# A.3.2 Cleaning the Exterior

Make sure that the system is turned off before cleaning the chassis 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.

# A.3.3 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-2780 power supply is capable of handling 100 to 240 V AC within the 50 Hz to 60 Hz range. Do not connect the PXES-2780 to an already overloaded circuit.
