Running the LLC

This procedure describes the available parameters for running the Low-Level Communicator (LLC) and how to run the LLC with or without any parameter specification.

Before you begin

The CSP system software must be installed before you can start the LLC. SwitchKit must also be installed on your system. The LLC parameters must not be already specified through the shortcut settings in the Start menu, refer to Configuring SwitchKit to Run from the Start Menu.

Steps to start the LLC with CSA

Do the following to start the LLC:

1 Go to the Start button, select Programs®SwitchKit®llc.

2 The llc window opens, indicates that it is ready to accept connections, and then minimizes.

3 Now you are ready to start SwitchManager.

Steps to start the LLC without CSA

Do the following to start the LLC:

1 Open a Command Prompt window.

2 Specify the path to your installation directory. For the default location C:\Program Files\Excel Switching Corporation\ SwitchKit.

3 Type llc and specify the start-up argument, if desired. You can use multiple arguments together. See the LLC Arguments.

LLC start-up behavior

When the LLC connects to the CSP, Poll messages from the CSP Matrix Series 3 card indicate the presence of system software on the CSP. If no system software is found, the LLC will wait until the system software is downloaded by the TFTP server. If a TFTP download is already in progress, LLC does not interfere and waits for the download to complete.

After the download is complete, messages.log or socket.log records all messages (such as polls) arriving from the switch. The maintenance_llc.pid.log file records administrative details.

When the LLC is running, all downloading has been completed, and the "**Ready to accept connections" message appears, SwitchManager can be started.

When LLC is running, it automatically sends the host system time to all the CSP Matrix Series 3 cards in the system.
