Install the Daisy-Chain Jumpers

Live Insertion

Sockets J4-J14 allow the daisy-chained bus grant arbitration and interrupt priority resolution processes to continue unaffected during live insertion or removal. These sockets, in conjunction with the headers for bus grant signal jumpers and the headers for IACK signal jumpers can be used with

auser-supplied daisy-chain switch module. This switch module incorporates the backplane daisy-chain bypass circuits.
