Full crate and production testing of the CMS regional calorimeter trigger system

The Compact Muon Solenoid (CMS) calorimeter regional trigger system is designed to detect signatures of isolated and non-isolated electrons/photons, jets, /spl tau/-leptons, and missing and total transverse energy using a deadtimeless pipelined architecture. This system contains 18 crates of custom-built electronics, including a backplane, boards, links and Application-Specific Integrated Circuits (ASICs). We present results from testing a completely instrumented and fully functional preproduction system. We also describe the production testing of the final system, including the custom software necessary to automate the process of testing a large quantity of high-speed and dense electronics.
