The router module runs Cisco standard software and fully interoperates with the:
3Com ONlineä Ethernet Router Module
Cisco local and remote router servers, such as the AGS+ä, MGSä, and the Cisco 3000, 4000, 4500, and 7000 series.
Router Module Architecture
Each router module consists of two components:
Engine Module - Provides Token Ring-to-WAN port connections.
Carrier Module - Provides connections to one of three 3Com switching hub products.
The engine mounts to one of three carrier types to form an Edge Router Module for the ONlineä, ONsembleâ, or ONcoreâ hub products.
The architecture of each Edge Router Module type is illustrated in Figure 1-2.

Introduction 1 - 7
Topology Switching Capability
The router module provides topology switching capability. Topology switching is the ability to switch the router module between token ring networks (rings) on the hub backplane using:
Network management module commands
Simple Network Management Protocol (SNMP)
You do not have to swap cables or move the router module to move the routing or bridging functions to a different network within the hub. You can enter a command through one of the 3Com management modules and the network change is made automatically.
Network Reliability
The router module provides the capability to implement several levels of reliability in your network:
By configuring the router module’s WAN and auxiliary ports in parallel, you can create up to three redundant serial links to protect your mission-critical applications.
You can configure up to two backup links to ensure that your applications are available if the primary link fails.
An example of the router module configured to provide reliability is shown in Figure 1-3. These serial links can also support load-balancing to augment the performance of your network.

IOS Router Software Updates
The IOS software in the router module engine can be updated by purchasing field-upgradable software distribution kits. Update your module to the latest 3Com release of IOS software by downloading new code to flash memory on the module. New updates are shipped automatically as part of the 3Com 1-year Router Software Subscription Service or you can purchase it from 3Com as a single unit update.
You can also purchase an upgrade kit to upgrade your IP/IPX, Desktop, or Desktop plus IBMâ software to a version with an enhanced feature set.
Contact your 3Com reseller or 3Com Customer Support for more information and part numbers.
Memory Upgrades
The router module provides the capability to increase memory to meet the requirements of large routing table configurations.
Memory is configured on the router module to match the requirements of the selected IOS software feature set. Table 1-2 lists the base memory configurations for each software feature set.
