Before you install your new module, follow the appropriate preinstallation

instructions in this section, depending on whether you are installing the

initial FDDI module or replacing one.

CAUTION: The FDDI module requires release 2.0.0 or higher of the

CoreBuilder 3500 system software.

Your system is shipped with no modules installed and with protective

faceplates covering the installation slots. Before you install the module,

remove the protective faceplate that covers the selected installation slot.

To remove a faceplate:

1 Loosen the two captive screws that secure the faceplate to the chassis.

2 Move the injector/ejector handles to the outward position.

3 Pull the faceplate away from the system. See Figure 2.
