The LANplex system will automatically reset when a module has been 
installed with the power on. 

If you physically change the configuration of the system after defining an IP 
interface, the port designated for that interface may no longer be valid. You 
may have to redefine the interface. For information on defining an IP inter-
face, see the Administration Console User Guide for your LANplex system.

 

Installing the

Module

 

To install the new module into the LANplex system, perform the following 
steps:

 

1

 

Ensure that you are properly grounded. 

 

2

 

Remove the module from its antistatic bag.

 

WARNING: 

 

If the system is powered on when you are replacing the module, 

do not insert any metal objects, such as a screwdriver or a finger wearing 
jewelry, in the open slot. This could cause burns or other bodily harm.

 

3

 

Place the module between the guides of the selected slot and slide the 
module into the chassis. See the figure below.
