3) Remove the termination strap from the Berg jumper pins labeled "JD 13" from each MPU's
PC board except the last one in the chain, as shown in Figure 576-1 .
4) Make connections between chassis: from each Port 1 Tx – to Tx – ; from each Port 1 Tx+ to
Tx+; from each Port 1 Rx – to Rx – ; and from each Port 1 Rx+ to Rx+, as shown in
