To determine why an MBM does not appear in Element Manager
1 Check that the correct feature for the expansion unit is included in your installed keycode.
2 Check 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 on the main unit.
3 Check that the MBM and expansion unit are enabled using either Element Manager or Telset
Administration. If the units are enabled, disable them, and then re-enable them.
4 Check that all the switches on the MBM are on. For more information about these switches,
see
Verifying the media bay module switch settings on page 94.
If the MBM is a GASM or GATM, all the switches on the right are not set to on. For
information about setting these switches, see
Verifying the media bay module switch settings
on page 94.
To check the MBM switches, you must remove the MBM from the expansion unit. For
instructions, see
Replacing a media bay module on page 179.
To determine why the ATA2 does not function
1 Check for a dial tone using an analog device.
2 Check that AC power is connected to the ATA2 unit.
3 Check that the correct feature for digital sets is included in your installed keycode.
4 Verify that the ATA2 is connected to a digital station port.
5 Allow sufficient startup time (30–60 sec).
6 Plug an analog device into the phone port of the ATA2 and check for a dial-tone.
To determine why there is no dial tone at the ATA2
1 If you hear no dial tone, replace a single-line telephone for the data communication device.
2 If you hear no dial tone at the ATA2 unit:
a Disconnect the line side of the ATA2. Connect a digital telephone to the ATA2 port.
b Check that the connection from the ATA2 to the BCM50 hardware works correctly.
