Introduction to Service Terminal

• A service terminal is a terminal which can be connected to a computer unit for system monitoring as well as fault investigation.

• Service Terminal session:– Local, connect directly to a computer unit through a serial interface.

– Remote, connect from MML session or Service Terminal session of another computer unit.

Service Terminal on DMX Units

• Maximum number of Service Terminal sessions:– 2 local sessions– 2 remote sessions

• Interface for local connection: serial port with RJ45 connector• Line properties

– Bit rate 9600 bit/s– 7 data bits– Even parity– 2 stop bits

• Optional settings– Auto wrap: off– xon/xoff protocol– local echo: off RJ45 to DB9 converter

ST program on DMX units

Prompt

Example:

XXXX:YYY> “:“ indicates service terminal session established by connecting a cable directly to a DMX computer units

XXXX is the physical address of computer unit where service terminal session opened. For example; 0000 stands for OMU-0.

YYY shows where you are in command menu tree. For example; MAN = main level, OSC = Operating System Command.

XXXX-YYY> “-” indicates service terminal session established remotely, either from an MML session or Service Terminal session in others computer units.

Otherwise same as above.

Physical address of OMU-1

Service Terminal on Chorus unit

• Maximum number of Service Terminal sessions

– 1 local session

– 2 remote sessions

• The same configuration for local connection as it is on DMX units

• Special handling for computer unit with child units, A2SU and DMCU, jumper position for local ST connection is applied

ST Program on Chorus Units

Prompt

Example

XXXX-$ “$” indicates service terminal session in a Chorus unit. There is no difference between local and remote session.XXXX is the physical address of computer unit where service terminal session opened. For example; 000A stands for A2SP-1.

Physical address of A2SP-1

ST Program Main Menu on Chorus Unit


Service Terminal Extensions

• Service Terminal extensions are programs which usually not included in the main menu.

• An extension needs to be installed first before it is available in the main menu.

• The extensions are loaded from system disk (WDU) or other removable media

• Some extensions, by default, are loaded onto a computer unit during the start-up phase

• These default extensions may be different in different units.


Installing ST Extensions on DMX Unit

1. List available extensions using LS; command

2. Take a note module ID (first three letter of an extension module name) you wish to install

3. Install using LP:<COMM>,<MOD_ID>; command

Example:

• Installing “Recovery Userpart” extension (RCJ) and use “J” key to execute the extension from the main menu.


Installing ST Extensions on Chorus Unit

• ST Extensions in Chorus unit are handled by using “loadext” command.

• Use ”loadext” with extension name. It will automatically match name to file name and loads from disk.

• Use option to load extension manually from disk.
