2.9. Single Board Stop/Start (Hot Swap)

DM3 H.110 capable boards can be individually stopped and started, allowing you to replace CompactPCI (cPCI) boards without shutting down the system or telephony application. This process is known as Hot Swap. The DM3 cPCI board that you wish to replace is first stopped and then physically removed from the system. Next, the replacement board is installed in the same cPCI slot as the original board and then started. The following restrictions apply to the Hot Swap process:

• You must use the NCM_StopBoard( ) function to manually stop the cPCI board before it is physically removed from the system.
• The boards that are being swapped must be identical board models. For example, a DM/V960-4T1-cPCI can only be swapped with another DM/V960-4T1-cPCI.
• You must use the NCM_StartBoard( ) function to manually start the replacement board.

Note: DM3 H.100 (PCI) boards can also be individually stopped and started, but not for the purpose of performing a Hot Swap. For example, you can stop and start a DM3 PCI board to re-download the firmware to the board.

For information about using these functions, see Chapter 4, Function Reference.
