3 Using Expansion Bay Modules and PC Cards

Using expansion bay modules

The floppy disk drive and the optional CD-ROM drive in your Macintosh PowerBook are removable modules, which you can easily switch or replace with another module. The place in your computer where modules go is called the expansion bay. (The floppy disk drive is installed in the expansion bay at the factory.)

You can switch the modules, such as the floppy disk drive and CD-ROM drive, or remove a module while the PowerBook is turned on, in sleep, or shut down. All expansion bay modules are inserted and removed in the same way.

To protect your work and to be sure that the computer recognizes which module is in use, first quit any programs that may be using files on the disk in that module. Then select the disk’s icon and choose Put Away from the File menu or drag the icon to the Trash.

IMPORTANT Don’t switch modules while the computer is starting up. Also take care not to remove a module if a floppy disk or CD-ROM is inserted and

in use.

If you purchase an expansion bay module from an independent supplier, be sure to follow the instructions that came with the device. Some modules may have special requirements, such as shutting down the computer before inserting or removing the module. At least one manufacturer makes an internal power adapter for use in the expansion bay.
