Check the wiring connections

After you check the power source and the LEDs, begin to check the wiring. Check the connections
between the following components:
• the expansion unit and the main unit
• the main unit and to the MBMs—make sure that the cables are properly seated and are
connected to the correct ports
• the power supply and the main unit and the AC power outlet
• if you are using a UPS, check the connection from:
— the USB hub to both the UPS and the BCM50
— the UPS and the electrical outlet,
— the connection from the power supply to both the UPS and the BCM50 main unit
• the lines and extensions connected through the RJ-21 telephony connector
• the auxiliary equipment—connections at the auxiliary terminal block, or at the patch panel

Verify the keycodes

If a specific feature is not functioning, verify that the feature is included in your installed
keycodes. This section provides procedure for verifying the installed keycodes using either
Element Manager or Telset. For more detailed information about retrieving and entering the
keycode for your system, see the Keycode Installation Guide (NN40010-301).
