# Using the Hot Swap features

Hot Swap operates only if the Hot Swap Driver and Hot Swap Manager are started. To learn how to start these modules, refer to the NMS OAM System User's Manual.

Under Windows, you must also install additional drivers to enable NMS Hot Swap drivers to interact properly with Windows Plug and Play functionality. These drivers are available with Natural Access.

Once the Hot Swap Driver and Hot Swap Manager are started, boards defined in the NMS OAM database may be booted, extracted, and reinserted. Boards inserted into a PCI bus and slot for which no logical board definition exists in the database are not recognized. For more information about configuring Hot Swap, refer to the NMS OAM System User's Manual.
