BCM50 Installation and Maintenance Guide
Installing a media bay module in an expansion unit
To install a media bay module (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. Refer to “To configure the MBM(s)” on page
150 for information on configuring an MBM.
4 Continue with the next procedure, “Installing the expansion unit”.
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.
Use one of the following procedures to mount the expansion unit:
• “Installing the BCM50 unit in an equipment rack” on page 80
• “Installing the BCM50 unit on the wall” on page 84
• “Installing the BCM50 unit on a desktop or shelf” on page 89
Next step
If you are installing a second expansion unit on the system, repeat the procedures in this section for
the second expansion unit.
After you have installed the expansion unit, go to “Connecting the cables to the BCM50 system”
on page 97.
