ADLINK PXES-2590 Chassis Deployment and System Management

ADLINK PXES-2590 Nine Slot PXIe Chassis Deployment and System Management Complete Guide

In high-end testing and measurement applications, the number of channels, module types, and system bandwidth are often key factors determining platform selection. ADLINK PXES-2590 is a 9-slot PXI Express chassis that offers 1 system slot, 1 system timing slot, and 7 hybrid peripheral slots, with a total system bandwidth of 8 GB/s and all peripheral slots having a bandwidth of 1 GB/s. Its industrial grade AC power supply can stably output 400 W power within a wide temperature range of 0 ° C to 55 ° C. Coupled with innovative heat dissipation design of bottom air intake and rear exhaust (dual 185.9 CFM fans), the cooling capacity of each slot reaches 30 W (verified by 55 ° C ring test), which is significantly better than similar products. In addition, the rear of the chassis provides a 10 MHz reference clock BNC input/output, suppression/voltage monitoring DB-9 interface, and intelligent fan control, and supports remote monitoring and alarm threshold setting through SMBus. This article is based on the PXES-2590 user manual and systematically explains the hardware installation, heat dissipation planning, system management configuration, SMBus programming interface, and common troubleshooting methods of the chassis, providing engineers with full stack guidance from deployment to operation and maintenance.

Overview and Core Specifications of the Chassis

PXES-2590 complies with the PXI-5 Rev. 1.0 specification and is compatible with PXI Express, CompactPCI Express, and hybrid slot compatible PXI-1/CompactPCI modules. The backplane adopts a four link PCIe switching architecture, and the system slot (Slot 1) supports system controllers with a maximum width of 4 slots. The system timing slot (Slot 5) provides single ended and differential star trigger functions, and the remaining 7 slots are mixed peripheral slots (Slot 2-4 and Slot 6-9). The key power parameters are as follows:

Communication input: 100-240 VAC (wide range 85-264 VAC), 50-60 Hz (47-63 Hz), maximum input current 13 A @ 115 VAC/10 A @ 230 VAC.

DC output (total available power 400 W):

+5V / 23.0 A， ± 3% adjustment rate, ripple ≤ 50 mV

+12V (system slot)/15.0 A, ± 3%, ripple ≤ 50 mV

+12V (peripheral slot)/16.0 A, ± 3%, ripple ≤ 50 mV

+3.3V / 33.0 A， ± 3%, ripple ≤ 50 mV

-12V / 1.75 A， ± 3%, ripple ≤ 50 mV

Reference clock: 10 MHz system clock slot skew ≤ 300 ps, built-in accuracy ± 50 ppm; BNC output is a 1 Vpk pk square wave (50 Ω load) with an output impedance of 50 Ω± 5 Ω; External input requires 10 MHz ± 100 ppm. The inter slot skew of the 100 MHz differential clock (PXIE_CK100) is ≤ 100 ps, with an accuracy of ± 25 ppm.

Machinery and Environment: Dimensions 321.9 (W) × 191.4 (H) × 465.3 (D) mm, net weight 8.8 kg; operating temperature 0~55 ° C, storage -20~70 ° C, humidity 10%~90%, no condensation; Anti impact 30G half sine, vibration working state 0.31 Grms, non working 2.46 Grms. Safety certification EN 61010-1, EMC complies with EN 55011 Class A and EN 61326-1.

Key points of installation and heat dissipation engineering

2.1 Unboxing and Attachment Confirmation

The standard packaging includes the PXES-2590 chassis, power cords, filler panel kit (1 3-channel panel and 9 single slot panels), and ADLINK All in One CD (including monitoring software and function library). If used for rack installation, the bottom support feet need to be retained to ensure air intake clearance. Any missing or damaged items should be immediately reported to the dealer.

2.2 Innovative heat dissipation design and gap requirements

The PXES-2590 adopts a horizontal air duct with bottom intake and rear exhaust, with dual fans located at the rear. Cold air is drawn in from the bottom and front openings, flows through all modules, and is discharged from the rear. This design can effectively avoid inhaling hot air discharged from adjacent equipment during rack installation, while maintaining uniform temperature in each slot. Key gap:

Bottom air inlet: Leave at least 1U (44.5mm) clearance;

Rear air outlet: at least 76.2 mm (3 inches) away from other objects;

All unoccupied slots must be equipped with filling panels (included) to maintain wind pressure and directional airflow.

If these requirements are ignored, even if the ambient temperature does not reach the upper limit, the temperature alarm inside the chassis may be triggered due to airflow short circuit or heat accumulation.

2.3 Installation of System Controller and Peripheral Modules

The system controller (recommended ADLINK PXIe-3975 Core i5-520E) is installed in Slot 1 and can occupy 3-4 slot widths. Installation steps:

Confirm that the CPU, memory, and storage on the controller are ready;

Press the module latch release button, smoothly push it in along the upper and lower guide rails, and lift the latch to fully engage with the back panel;

Tighten the fixing screws on the front panel and connect external devices such as the monitor and keyboard.

The peripheral module is installed in Slot 2-9 (Slot 5 is the system timing slot and can also be used as a regular peripheral slot). The operation is similar: select the slot, insert along the guide rail, lift the latch, and tighten the screw. All empty slots must be equipped with filling panels. When powering on, connect the power cord to the C13 entrance at the rear, press the power button on the front panel, and the blue Power LED will light up, indicating normal operation.
