The Agilent E1302A VME/VXI mainframe is a high-performance, 350 W VME/VXI B-size VXI mainframe. It provides a quality environment for larger scale B-size system configurations. Its backplane provides 20 slots with VME/VXI P1 and P2 row B connectors. Agilent Technologies has incorporated its industry-leading Pressurized Air Channel cooling system into the design of the E1302A. It ensures clean, uniform airflow to each module. For greater air flow, cooling air intake is through the rear of the mainframe. Additionally, power supply and fans are serviceable through the rear. The implementation of solid state automatic daisy-chain jumpering for the VMEbus grant and interrupt acknowledge lines eliminates the need for hand selection of switch settings.
