Default Factory Configuration System Overview

iMG/RG Software Reference Manual (LAN Module Management)
10. LAN Module Management
The iMG Mods, including the iMG626, iMG646, iMG726, and iMG746, support multiple LAN modules. Each
LAN module can be used to provide a different type of service.
10.1 System Overview
10.1.1 Default Factory Configuration
When a LAN Module is detected, a port is created that corresponds to the service on that LAN module. Spe-
cifically for the HPNA daughter-card, an HPNA ports is created and attached to the default VLAN. If the CES
daughter-card is created then the ports CESD and CESC are created. The CESD port is attached to the default
VLAN and is used to transport the E1/T1 data. The CESC port is for management – and is automatically man-
aged by the software.
10.1.2 Adding/Removing & Changing LAN Modules
When a new LAN module is added or changed to a different type, it is recommended that the user set the con-
figuration back to the factory mode and remove all current saved configurations. This ensures that the base
configuration is clean and only reflects what is in the device. The iMG Mod will then need to be reconfigured
with the new LAN module features as well as any non-module based configuration such as voice or internet.
WARNING: Power MUST BE REMOVED before changing the LAN module. Damage to the device can result
if these directions are not followed.
10.1.3 Device and Module Compatibility
When LAN and WAN modules are added to the devices, they utilize resources within the device to prvide the
service that they are offering. There are some WAN modules that require resources that are only available on
Later Modular units and there are some LAN Modules that require resources that are also required by some
LAN modules. In this architecture - the LAN Module always wins - so if a LAN Module is added that conflicts,
then the ports associated with it will not be created, a Log will be created - and the LAN LED will go red - and
stay red.
