Rack-mount chassis 1261B

9U7U12 slots

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. Product Information Power 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 de- livery. 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-pur- pose 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 fea- ture a variable speed cooling system that adjusts fan speed based upon the worst slot temperature rise.
