To determine why an MBM does not appear in Element Manager

1Check that the correct keycode has been entered for the expansion unit.

2Check that both the Power and Status LEDs on the MBM are solid green.

•If the Power LED is off, check that the power supply cable is properly seated in the expansion unit and the power supply is connected to a working power outlet.

Also check that the MBM is properly seated in the expansion unit.

•If the Status LED is not solid green, check that the Expansion cable is properly seated in the Expansion port on the expansion unit and the main unit.

3Check that the MBM and expansion unit are enabled, using either Element Manager or Telset Administration. If they are enabled, disable them, then enable them again.

4Check that all the switches on the MBM are set to on. Refer to “Verifying the media bay module switch settings” on page 93 for more information about these switches.

If the MBM is a GASM or GATM, all the switches on the right are not set to on. Refer to “Verifying the media bay module switch settings” on page 93 for information about setting these switches.

To check the MBM switches, you must remove the MBM from the expansion unit. Refer to “Replacing a media bay module” on page 179 for instructions.

To determine why the ATA2 does not function
