# 1 Introduction

Get ready to take your testing and measurement applications to the next level with the ADLINK PXES-2788 Series chassis. With its high-performance 18-slot PXI Express backplane, high-output power supply, and cooling capacity, it's designed for heavy-duty and high port density applications. The modular design ensures a high level of maintainability, with replaceable power supplies for high-availability applications, resulting in a very low meantime to repair (MTTR).

Fully compliant with the PXI-5 PXI Express hardware specification, the PXES-2788 Series offers advanced timing and synchronization features for high clock accuracy and external clock and trigger routing. Using PCI Express 3.0 technology, the chassis boasts a system bandwidth of up to 24GB/s for high-throughput, peer-to-peer data transfer applications, and up to 8 GB/s bandwidth for all peripheral slots.

The PXES-2788 Series provides up to 102W power and cooling capacity per slot, allowing for higher power budgets for high-performance and power PXI modules. And with a smart system monitoring controller that reports chassis status, including fan speed, system voltages, and internal temperature, you can be sure that your system is running at optimal performance. The smart fan function dynamically adjusts fan speed based on the embedded temperature sensor to achieve a balance between sufficient airflow and operating noise.

Experience the power and versatility of the ADLINK PXES-2788 Series chassis and take your testing and measurement applications to the next level.

# 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 (PXI\_LBL6 and PXI\_LBR6) on a PXI Express backplane. The remaining local bus lines can transmit analog or digital signals between modules.

# Trigger Bus

Three trigger bus segments (segment 1: slots 1-4 and slots 19- 21 on PXES-2788E, segment 2: slots 5-11, segment 3: slots 12-18), 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.

Trigger bus bridges can be configured as connected or disconnected (default) for 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-2788 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-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.

The PXES-2788 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 SMA female connector
 PXI\_CLK10\_IN pin on the system timing slot (slot 10)

Priorities for 10MHz reference clock are as follows.

<table><tr><td>System Timing Slot (10th slot)</td><td>Front Panel SMA Female Connector</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 SMA 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 Power Supply Budget Considerations

Please review the power consumption of all modules used in the same PXES-2788. The total maximum power consumed by the system module and peripheral modules shall not exceed the DC power supply of the PXES-2788 as defined in DC Power Output on page 4 and Backplane Slot DC Power Current on page 5.

# 2.3 Cooling Considerations

The PXES-2788 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-2788, keep a 10.2 cm / 4 in. clearance at both the rear and top sides of chassis.

![The image displays a white document icon with a folded top-left corner and horizontal lines representing text. A large, bold red checkmark is superimposed over the document, extending diagonally from the bottom left to the upper right.](.pxes-2788-50m-00143-1010-11/a4beaee5f2ad5fdbd6fd0bd902f3b4593dfc08e713198e20d276425532330aae.jpg)
NOTE:

To maintain expected air flow, please always install filler panels in unused slots. The filler panels can be found in the chassis package.

# 2.4 Configure Settings for Cooling

Heat ventilation is related to the installation location, environmental temperature, and total heat generated by the system module and peripherals. The PXES-2788 features a smart fan function to provide sufficient ventilation and minimize noise emission. There are two switches located at rear of the chassis to configure the smart fan operation.

# 2.4.1 Fan Mode Switch

Normal - Aims to provide sufficient ventilation to peripheral modules’ power to consume less than 60W per slot with controlled noise emission.

Boost - For peripheral modules up to 85W / 102W power consumption needing more ventilation.

![A white document icon featuring horizontal lines, overlaid with a large red checkmark.](.pxes-2788-50m-00143-1010-11/21eb6718aca851a587099096f7a19fdea9ffdfd08fb0d407b428d47c30a3d5bf.jpg)
NOTE:

Set fan mode switch to Boost Mode if ambient temperature will be greater than 45°C/114°F (up to 85W) or 40°C/104°F (up to 102W). Up to 102W supported by PXES-2788/HP and PXES-2788E/HP that are equipped with additional top fan.

# 2.4.2 Fan Speed Switch

Auto - Enables smart fan function.

High - Full fan rotation utilization, two profiles based on Fan Mode Switch (Normal or Boost).

The following table explains specific conditions and recommended settings.

<table><tr><td>Heat Dissipation Requirements</td><td>Recommended Settings</td></tr><tr><td>When all peripheral modules require less than 60W cooling capacity per slot</td><td>Sets Fan Mode as Normal, and set Fan Speed Switch to Auto.</td></tr><tr><td>When one of all peripheral modules require more than 60W cooling capacity per slot</td><td>Sets Fan Mode to Boost, and set Fan Speed Switch to Auto.</td></tr><tr><td>Maximize ventilation for peripheral modules</td><td>Sets Fan Speed to High, and sets Fan Mode Switch based on requirements.</td></tr></table>

# 3.1.3 Smart Fan

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 $5 0 ^ { \circ } \mathsf { C }$ as an example, fans run at 40% when all temperature readings are less than $2 5 ^ { \circ } \mathsf { C }$ , and begin ramp-up when any reading exceeds $\boldsymbol { 2 5 ^ { \circ } \mathrm { C } }$ .

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

Setting parameters are as shown.

# Appendix A - Maintenance

This Appendix describes basic maintenance and troubleshooting instructions for the PXES-2788 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-2788 is designed for both rack-mount and bench top 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-2788 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-2788 power supply is capable of handling 100 to 240 V AC within the 50 Hz to 60 Hz range. Do not connect the PXES-2788 to an already overloaded circuit.

# A.3.4 Replacing the Power Supply Module

The power supply module of PXES-2788 is with removable design that can be replaced in the field based on maintenance requirements. The power supply module can be ordered individually as backup part. Please contact your ADLINK sales window for more information.

The power supply module can be removed by removing all AC power and pulling out the PSU by pushing the latch, and then installing a replacement PSU by pushing it into position until the latch is locked.
