# Overview of setting up NMS OAM

Administrators can use NMS OAM to set up hosts in single host configurations or in multiple-host configurations.

## Single-host configurations

If your configuration consists of only one host, follow these steps to set up NMS OAM:

Step | Description | Documented in...
--- | --- | ---
1 | Ensure that your chassis is set up properly for Hot Swap boards. (Required only if you are using Hot Swap.) | Configuring Hot Swap
2 | Install NMS OAM software. | Natural Access installation booklet
3 | Start the Natural Access Server (ctdaemon), if it is not already running. Also start Hot Swap. | Starting the Natural Access Server Starting Hot Swap
4 | Create a system configuration file describing your system. In this file, give each board a unique name and board number. | Creating a system configuration file
5 | If your system contains two or more boards connected through the H.100 or H.110 bus, configure clocking on the bus. | CT bus clocking overview
6 | Use oamsys to create records for components in the NMS OAM database based upon the system configuration file, and to start all installed boards. | Using oamsys Board identification methods

## Multiple-host configurations

To set up a multiple-host NMS OAM configuration, follow these steps:

Step | Description | Documented in...
--- | --- | ---
1 | Determine which systems will serve as resource hosts, and which one will serve as the management host. |
2 | CompactPCI only. Ensure that each host chassis is set up properly for Hot Swap boards. (Required only if you are using Hot Swap.) | Configuring Hot Swap
3 | Install NMS OAM software on each host. | Natural Access installation booklet
4 | Start the Natural Access Server (ctdaemon) on each host, if it is not already running. Also start the Hot Swap driver and the Hot Swap manager. | Starting the Natural Access Server Starting Hot Swap
5 | Create system configuration files, one for each resource host. In each file, give each board in the host a unique name and board number. | Creating a system configuration file
6 | If a host contains two or more boards connected through the H.100 or H.110 bus, configure clocking on the bus. | CT bus clocking overview
7 | Use oamsys to create records for components in the NMS OAM database on each host based upon the system configuration file, and to start all installed boards. | Using oamsys Board identification methods
