Agilent E1421B Cooling Specification Charts
Backplane
• High performance
• Monolithic
• 6 slots
• VXI P1 and P2 connectors
The backplane features solid state automatic daisy-chain
jumpering for the VMEbus grant and interrupt acknowledge
lines, eliminating the need for hand selection of switch
settings. The E1421B backplane is compatible with the
Agilent backplane connector shield kit, P/N E1400-80920.
