EADS North America Test and Services Racal Instruments™ 1261B High-Performance VXI Chassis Modern test environments cannot tolerate downtime. The mainframe must keep running continuously. The 1261B takes advantage of our years of experience as a leading VXI mainframe manufacturer to deliver maximum performance and reliability at a price that is competitive with low-end units. Key Features • Highest cooling level of any general-purpose VXI mainframe • Fault-tolerant cooling system • Two choices of monitoring options • Independently pluggable power supply and fan assemblies • Monitoring option is independently powered and needs no VXI slots Product Information selected, if desired, to achieve maximum reliability of fielded systems Power 7U and 9U Versions The 1261B power supply features an advanced design that delivers abundant power with a minimum of ripple and noise. The power supply plugs directly into the backplane for the best possible power delivery. High dynamic current ensures crisp waveforms and accurate measurements. Cooling Our fourth generation, 13-slot mainframe incorporates many unique technological advances to deliver the most cooling and highest VXI-8 curves of any general-purpose VXI mainframe. This ensures the lowest temperature rise in your VXI modules for the most reliable system operation possible. The mainframe features a pressurized plenum system for even airflow distribution from front to back and side to side. Unique, molded card guides direct airflow through installed modules rather than between them. Snap-on covers divert airflow away from unused slots. The 1261B features a fault-tolerant cooling system using a rear-pluggable assembly with three fans. If a fan failure should occur, the two remaining fans still deliver a high level of cooling, preserving your VXI module investment. Basic 1261B units include a HI/LO cooling switch to minimize audible noise during system development and maximize the reliability of fielded systems. Units equipped with a system monitor feature a variable speed cooling system that adjusts fan speed based upon the worst slot temperature rise. This ensures ample cooling while minimizing audible noise. A rear switch permits maximum cooling to be The 1261B mainframes are available in two sizes, 7U and 9U. The 9U mainframes are ideal for rack-mount applications. They draw in air from the sides of the mainframe and exhaust out the rear to minimize rack “chimney effects.” They also include a 2.25” deep cable tray. The 7U mainframes are ideal for benchtop and space-limited applications. They draw in air from the rear of the mainframe and exhaust out the top. Base Unit All 1261B chassis include full power protection features, such as over-voltage and under-current protection. All 1261B chassis include a quick-check diagnostic connector to verify performance of power supply voltages, currents and specific VXI signals. Optional Standard Monitor System (SMS) The SMS automatically checks that all mainframe parameters including VXIbus voltages, currents, airflow, and temperature rise are within factory limits at all times. Bi-color LED annunciators on the front of the mainframe show system status and will indicate a problem if parameters are out of limits. This contrasts with low-end mainframe monitors that merely check for ECO# 2010-EADSTS-12-13-10-MU. Uncontrolled Unclassified Information (“UUI”).
