To troubleshoot the main unit
If a test fails, use the following procedure:
1 Verify that any nonfunctional feature is included in your installed keycode.
2 Check the wiring to the main unit and to the MBMs. Make sure that the cables are properly seated and are connected to the correct ports.
3 Reboot the BCM50 system.
4
Check LEDs (see Viewing the BCM50 system LEDs on page 61).
5 Use Element Manager or the Telset Administration feature to check the programming for the lines or extensions that failed the call test.
6 If the programming is incorrect, use the Backup and Restore Utility to load a recent backup of system programming. If a recent backup is not available, correct the programming using
Element Manager or the Telephone Administration feature.
To test the expansion unit
Use the following test to ensure the expansion unit is operating properly:
1 Make sure that the BCM50 system is fully booted. For indications that the system is fully operational, see
Viewing the BCM50 system LEDs on page 61.
2 Check the power and status LEDs on the MBM that is inserted in the expansion unit. Both
LEDs must be solid green. If either LED is not solid green, a problem exists with the MBM or the expansion unit. For a detailed description of the LED states, see
Viewing the BCM50 system LEDs on page 61.
3 If the expansion unit has an MBM that supports extensions, go to an extension that is connected to the MBM.
4 Check for a dial tone.
5 Use this extension to make a call to another extension on the system.
6 If the expansion unit has an MBM that supports lines, go to an extension that has access to one of the lines on the MBM.
7 Select the line or line pool to which the line belongs.
8 Check for a dial tone.
9 Make a call using the line or line pool.
To troubleshoot the expansion unit
1 Check that the correct feature for the expansion unit is included in your installed keycode.
2 Check that the expansion port is connected to the proper connector. For location of the LAN ports, see the figure
on page 100 and the figure Connecting the expansion unit to the BCM50 main unit on page 101.

Chapter 18 Testing basic BCM50 functionality 163
3 Check the wiring to the MBM. Make sure that the cables are properly seated and are connected to the correct ports with proper LED indications.
4 Check that the switches on the MBM are all set to 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 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.
5 Perform a firmware download to ensure that the correct version is loaded on the ASM/GASM or GATM unit.
6 Use Element Manager or Telset Admin to check the programming for the lines or extensions connected 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 of system programming. If a recent backup is not available, correct the programming using
Element Manager or the Telephone Administration feature.
To test the MBM
1 Check the Power and Status LEDs on the MBM. Both LEDs must be solid green. If either
LED is not solid green, a problem exists with the MBM. For a detailed description of the LED
states, 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 station
MBM, use
163 and To test a trunk MBM on page 163.
To test a station MBM
1 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 MBM
1 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.

164 Chapter 18 Testing basic BCM50 functionality
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.
NN40020-302
Chapter 18 Testing basic BCM50 functionality 165
To check the ATA2 wiring
1 Use an analog phone to test the ATA2.
2 Check the following connections: a ATA2 to the terminal
The resistance must be 200 ohms or less for data applications and 1300 ohms or less for voice applications.
b BCM50 hardware to the ATA2
The wiring must be equivalent to 800 m of 0.5 mm wire (2600 ft. of 24-AWG) or less. Do not use bridge taps and loading coils between the BCM50 hardware and ATA2.
Reset to factory settings
This section describes how to reset the BCM50 system to the factory settings or a stable working condition using the reset switch (see the figure Reset switch location on page 165). When the
BCM50 is in this condition, you can make further modifications.
Figure 68 Reset switch location
Reset switch
Some possible situations in which you use the reset feature are:
• If the BCM50 system is configured incorrectly to an extent that it is no longer functional. The customer must use a level 1 reset to return to the default system programming and restore a previous configuration or reconfigure the system.
• If distributors want to reuse BCM50 systems, they must first erase all customer-specific data using a level 1 or level 2 reset.
Reset levels
Reset to factory settings is a stand-alone feature that has the following levels of reset:
• Level 1 reset erases all customer-specific data and restores the default configuration for all components. This reset leaves the software components untouched. That is, the system has the latest release and patch level of the software installed. Only the system and user configuration data is erased and replaced with default values. No Ethernet connectivity to the system occurs during this operation.
Installation and Maintenance Guide
166 Chapter 18 Testing basic BCM50 functionality
• Level 2 reset erases all customer and system configuration data and all software releases and patches. This reset re-installs the original factory configuration settings. Level 2 reset also resets the router firmware to what was shipped from the factory. No Ethernet connectivity to the system occurs during this operation.
Warning: If you perform a Level 2 reset to solve an undetermined problem and still have access to Element Manager, you must retrieve all the log files for technical support before performing the Level 2 reset. A Level 2 reset erases all log files from the system.
Activate the reset feature
You activate the reset feature by pressing the reset switch with a long, thin, nonmetallic needle in
the sequence described in the procedure To perform a Level 1 and Level 2 reset on page 166.
Warning: Before performing a Level 1 or Level 2 reset, review all the effects of
the levels of reset. See Reset levels on page 165.
As you press the reset switch, the LEDs blink in a predefined fashion to guide and confirm user input. The various states of the power and status LEDs indicate the following:
• A blinking power LED indicates a user input window; the BCM50 system is waiting for user input.
• A solid red power LED indicates extreme action is requested; caution is urged.
• A solid status LED (any color) indicates level of reset action:
— Level 1 is yellow
— Level 2 is red
• A blinking status LED indicates an interim state; trying to establish user request.
• A solid status LED indicates confirmation of a user selection (power LED has priority).
To perform a Level 1 and Level 2 reset
The router configuration of a BCM50a or BCM50e is not affected by a Level 1 reset. To perform a soft reset on the router, use Element Manager.
See the figure Level 1 and Level 2 reset sequence on page 167, or follow the sequence in the table
Level 1 reset on page 168 and the table Level 2 reset on page 168 to perform a Level 1 and Level 2
reset.
