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) h2. Configuration tools 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: <pre> OSE Delta PowerPC/BL410660 Start of @(#)CXC1729957 R80L37 2013-02-01 10:34:51 GMT Plug-in Unit Product Name: DUL2001 Plug-in Unit Product No: KDU137533/4 Plug-in Unit Product rev: R1F Plug-in Unit Product Date: 20120402 Plug-in Unit Product Serial: XXXXXXXXXX Ethernet MAC_address 0: 0x3CCAFFEE2342 RAM size: 1024 Mbytes </pre> Press enter to show the login prompt `username`.
