# Using the Hot Swap features

Hot Swap functionality is an integral part of NMS OAM. It is designed for use with the CX 2000C boards and is supported on Windows and UNIX systems.

The CX 2000C board includes a switch built into the ejector handle and an end bracket Hot Swap LED. When you insert a board into the system, the switch signals that the board is fully seated with the handle closed and that the software connection can be initiated. When you remove a board, the switch signals that the board is being extracted and that the software disconnection can be initiated.

When lit, the Hot Swap LED indicates that the software disconnection is complete and extraction is permitted. You can open the handle the rest of the way and eject the board. Refer to the NMS OAM System User's Manual for information on configuring and starting the Hot Swap process.
