Prior to installing the SIMs, set the jumpers on header J8 (for Serial Port
3) and header J9 (for Serial Port 4) for either DCE or DTE. Set the jumper
to position 1-2 if the SIM is for a DTE interface. Set the jumper to position
2-3 if the SIM is for a DCE interface.
You must set the jumpers and install the SIMs prior to installing the
CPX750HATM transition module in the system chassis.
The SIMs plug into connector J23 (for Serial Port 3) or J1 (for Serial Port
4) on the CPX750HATM transition module.
Install the SIMs on the CPX750HATM transition module per the following
procedure:
1. Align the SIM so that P1 on the SIM lines up with the appropriate SIM
connector (J23 for Serial Port 3 or J1 for Serial Port 4) on the transition
module. Note the position of the alignment key on P1. See the next
figure.
2. Place the SIM onto the transition module SIM connector, making sure
that the mounting holes also line up with the standoffs on the transition
module.
