# Verifying the board installation

To verify that you have installed a CX 2000 board correctly:

1. Install the CX 2000 board, as described in Installing the hardware. For simplicity, ensure that no other telephony boards are driving bus clocks.

2. Install the software. Refer to the Natural Access installation booklet for more information.

3. Connect the power supply to the rear power connector as described in Using the NMS rack mount power supply chassis.

4. Run pciscan to determine the location of NMS boards on the system.

To run pciscan, enter:

pciscan

pciscan displays the PCI bus and PCI slot locations of the boards that are configured in the system.

To flash an LED on a specific board under Windows, run pciscan with the PCI bus and PCI slot locations. For example:

pciscan 2 14

The Board Locate LED begins flashing. Press any key to stop the flashing LED. For more information about pciscan, refer to the NMS OAM System User's Manual.

5. Edit the system configuration file to reflect the PCI settings. For information about this file, refer to Configuring and starting the system using oamsys.

6. Configure the target board to operate in standalone mode by driving clocks with the internal oscillator. To do so, add the following keyword statements to the board keyword file:

Clocking.HBus.ClockMode = STANDALONE
Clocking.HBus.ClockSource = OSC
SwitchConnections = Auto

7. Attach a telephone to the port for station number 1. Port numbering is 1-based; timeslot numbering is 0-based. To determine the timeslot for a port, subtract 1 from the port number.
   For information on attaching telephones to the board, refer to Connecting to station telephones.

8. Run the oammon utility to monitor for board errors and other events.

9. Run oamsys to boot the board. oamsys interprets the system configuration file and loads the parameters in the keyword files to the boards. oamsys searches for configuration files in the AGLOAD path.
   To run oamsys, open a command window and enter oamsys.
   For information about oamsys, refer to the NMS OAM System User's Manual.

10. Examine the oammon output for errors and other events.
