h1. DUL 20 Configuration

The DUL can be configured via

* OSS-RC (Ericsson operations support system-radio and core - a centralized server)

* EMA (Element Manager - a Windows WebUI utility)

* moshell (a javabased command line utility - runs on linux)

* ncli (a command line utility which runs on the DUL itself)

h3. EMA - Element Manager

There are different versions of this tool. An ancient version can be downloaded from the DUL itself:

http://169.254.1.10/em/index.html

h3. ncli

With the ncli basic operations can be performed. However the ncli usually doesn't have a ManagedObject tree loaded which means it doesn't know which attributes an ManagedObject can have.

h3. moshell

The most powerful tool to configure the DUL. It loads the ManagedObject on startup. But can also operate offline on backups.

See [[moshell]] for further information how to install and use it.

h2. Backup & Recover

A backup of the DUL can be created via ftp and serial.

The serial is required to boot into the recovery mode.

h3. Backup

Configure the serial connection to **9600** baud (alternative **115200**).

Restart the DUL by removing the power for 5 seconds.

If the connection is working a boot message is shown:
