Note: The GASM and GATM MBMs have a different dip switch configuration than shown in Figure 40. Refer to “To set GASM dip switches” on page 94 and “To set GATM dip switches” on page 94 for more information.

Verify that the dip switches for your MBMs are in the default factory positions as follows:

If you are installing a DTM, BRIM, 4x16, DSM16, DSM32, or ASM8, ensure that all the switches are on. This is the default setting for the MBM switches. After you have set the switches, proceed to “Installing a media bay module in an expansion unit” on page 95.

Caution: The MBM dip switches must remain in their default factory position. Any required modifications to the MBM settings are made through the software.
