Chapter 18 Testing basic BCM50 functionality 167Installation and Maintenance Guide3 Check the wiring to the MBM. Make sure that the cables are properly seated and are connectedto the correct ports with proper LED indications.4 Check that the switches on the MBM are all set to on. For more information about theseswitches, see Verifying the media bay module switch settings on page 96.If the MBM is a GASM or GATM, all the switches on the right are not on. For informationabout setting these switches, see Verifying the media bay module switch settings on page 96.To check the MBM switches, you must remove the MBM from the expansion unit. Forinstructions, see Replacing a media bay module on page 183.5 Perform a firmware download to ensure that the correct version is loaded on the ASM/GASMor GATM unit.6 Use Element Manager or Telset Admin to check the programming for the lines or extensionsconnected to the MBM.7 Reboot the system to ensure that the BCM50 main unit functions correctly.8 If the programming is incorrect, use the Backup and Restore Utility to load a recent backup ofsystem programming. If a recent backup is not available, correct the programming usingElement Manager or the Telephone Administration feature.To test the MBM1 Check the Power and Status LEDs on the MBM. Both LEDs must be solid green. If eitherLED is not solid green, a problem exists with the MBM. For a detailed description of the LEDstates, see Media bay module LEDs (expansion units only) on page 66.2 Perform a call test to make sure the new MBM functions correctly. If you replaced a stationMBM, use To test a station MBM on page 167. If you replaced a trunk MBM, use To test atrunk MBM on page 167. If you replaced a 4x16 MBM, use To test a station MBM on page167 and To test a trunk MBM on page 167.To test a station MBM1 Go to an extension on the MBM.2 Check for a dial tone.3 Use this extension to make a call to another extension on the system.4 Use this extension to make a call to an external telephone number.To test a trunk MBM1 Go to an extension that has access to one of the lines on the MBM.2 Select the line or line pool to which the line belongs.3 Check for a dial tone.4 Make a call using the line or line pool.
