Apple Macintosh PowerBook 1400 - Manual (Page 34)

Inserting an expansion bay module
Follow these steps to insert an expansion bay module:
1 Make sure the computer is in sleep or shut down.
2 Slide the module in until you hear it click into place.
Make sure the gripping surface is facing down. Use a smooth motion but don’t
move the module too slowly. (The computer may not recognize the module if
you insert it very slowly.)
The latch clicks closed when the module is in place.
The figure above shows a CD-ROM drive. Follow the same procedure to
insert any expansion bay module.
Using a CD in the CD-ROM drive
Many PowerBooks have the optional CD-ROM drive installed in the
expansion bay at the factory. If you have a CD-ROM drive, you insert or
remove it in the same way as any other module.
Insert the CD-ROM drive module
all the way in until it clicks. Check to see if the latch
returns to the right.
