Remove the cover plate from the I/O panel at the rear of the IPE module.
Remove the I/O panel retaining screws and lift the I/O panel from the module.
Set up the I/O panel filter connector for the card slot you have assigned for
the MICB card installation.
Your next step depends on the configuration of that filter connector.
a If this connector has a permanent connection to the backplane cable,
remove the filter connector from the I/O panel.
b If a 50-pin connector joins the filter connector and the backplane cable,
disconnect the 50-pin connector from the I/O panel filter connector. Then,
being careful to save the retaining screws, remove the filter connector
from the I/O panel.
Install the NT5D52AC Ethernet Adapter card into the selected I/O panel
connector cutout using the saved retaining screws.
Fasten the I/O panel to the module using the retaining screws.
Replace the module cover plate.
