Chapter 4 Operation

4.11.1 Software Update from a Remote Data Center

The procedure to perform a software update from a Remote Data Center (RDC) is as follows:

1. The user should enter:

CNUPI:DTYPE=SOFTWARE,RDC=<rdc id>,

DIRECTORY=<subdirectory>,FILE=<filename>;

to request that the software be updated from a RDC where the software update files are stored in a

subdirectory in the ftproot.

Note: The directory and filename are optional and when not used the system looks for the file sgw.tgz in

the ftproot directory. If <filename> is specified, it should be specified without an extension.

2. Once you have confirmed that the software should be upgraded, the distribution file is transferred to the

Signaling Gateway without further interaction with the user. The unit indicates that the file has been

successfully transferred by displaying the “EXECUTED” response to the CNUPI command.

3. On completion, you should restart the system by executing the MNRSI command.

4.11.2 Software Update from Portable Media

The following procedure assumes that a CD-ROM or USB drive with the updated software has already been

created. Perform the software update as follows:

1. Insert the CD or USB into the Signaling Server.

2. Enter the following command:

CNUPI:DTYPE=SOFTWARE,DIRECTORY=<subdirectory>,FILE=<filename>;

to request that the software be updated from the media.

Note: The directory and filename are optional and when not used the system looks for the file sgw.tgz in

the root directory.

3. Prompts are displayed asking first if you are certain that you wish to upgrade the software and then to

insert the portable media.

The software is uploaded from the distribution portable media to the Signaling Gateway. The unit

indicates that all files have been successfully transferred by displaying the “EXECUTED” response to the

CNUPI command.

Following installation, the CD will be ejected from the CD-ROM drive to prevent the updates being

overwritten in subsequent restarts.

4. The user should restart the system by entering the MML command MNRSI.

4.11.3 Software Update from Startup

You are also able to update the software from system start. Installation of software from system start is not

normal operating procedure and should only be used if you are unable to install software via MML. A failed

installation of software from system start can result in the system failing to operate. The procedure to install

software from system start using either FTP or portable media is as follows:

Software Update from Startup Using FTP

1. Rename the software distribution to sgw.tgz.

2. Establish an FTP session (see Section 4.9, “FTP Access” on page 30).

3. Set the FTP transfer mode to “Binary”, since the software file is a binary file.

4. Transfer the software to the Signaling Gateway by typing the command “put sgw.tgz sgw.tgz”.

Note: The Signaling Gateway uses a case-sensitive file system. Therefore, it is necessary to specify

sgw.tgz in lowercase.

5. Terminate the FTP session by entering “quit” or “bye”.
