Local Control Module Configuration Procedure

Introduction

The LCM needs to know the hub/node's hardware configuration (number of
EDFAs, optical switches, receivers, transmitters, power supplies, and AC lines
mounted or connected) so that it can control the node's behavior correctly. If an LCM
was mounted in the node at the manufacturer, it should be configured correctly as
shipped. The configuration data is stored in an EEPROM residing on the LCM main
board.

Configuring the LCM

When necessary, the LCM can be configured using two different methods, as
follows:
Automatically using the Auto-Setup button

Manually using the PC-based ViewPort software

The following sections describe these procedures in detail.
Configuring the LCM Using the Auto-Setup Button
The LCM can determine the modules installed in the hub/node by using a discovery
method that is initiated by pressing the Auto-Setup button on the LCM front panel.
Important: In order for a module to be detected and counted as "installed", it must
be functioning properly at the time the Auto-Setup button is pressed. This includes
proper optical levels being fed to the receivers, optical switches, and EDFAs.
Perform the following steps to initiate module discovery through the LCM using the
Auto-Setup button.
1 Connect power to the node.
2 Connect optical fibers to all installed receivers.
3 Press and release the Auto-Setup button on the LCM.
Note: Use a small diameter screwdriver, or other small round tool that fits the hole
in the housing, to press the Auto-Setup button. Do not press hard. The button only
depresses about 1/64 inch (0.4 mm). You can feel the button depress, but likely not
hear it in a noisy environment.
Results: When the Auto-Setup button is pressed, the LCM checks for installed
modules and discovers the type of each module.
The Auto-Setup process typically takes up to five seconds.
