Installing a media bay module in an expansion unit
Follow this procedure to install a media bay module (MBM).
To install an MBM
1 Attach one end of a grounding strap to your wrist and the other end to a grounded metal
surface.
2 With the face of the MBM toward you, insert the MBM into the expansion unit.
3 Push the MBM completely into the expansion unit. You hear a click when the MBM is firmly
seated in the expansion unit.
The MBM must be configured for it to function. For information about configuring an MBM,
see the procedure
To configure the MBM(s) on page 152.
4 Proceed with Installing the expansion unit on page 97.
Installing the expansion unit
Make sure that the expansion unit is installed close enough to the main unit so that the supplied
expansion cable can be connected between the expansion unit and main unit.
The expansion unit can be mounted in a rack, on a wall, or on a desktop. Typically, the expansion
unit is mounted in the same way as the main unit.
