Boundary Scan Tests Ensure Midplane Quality

摘要

At Alcatel-Lucent, we test chassis-level products that provide 42 board slots on a midplane, essentially a passive backplane that accepts boards on its front and rear sides. Thirty-four of those slots accommodate many types of boards. Typically, we fill all empty slots to perform functional slot testing in addition to tests we run with only the boards designed for integration into a customer's equipment. This type of functional slot testing verifies all chassis slots work properly, and it supplements tests we run to ensure the customer's plug-in boards meet specifications.
