Description
Network Topologies Supported
The A900-IMA3G-IMSG Cisco ASR 900 Combo 3G Multirate iMSG and CEM Interface Module is a versatile module that supports a range of network topologies. Here are some examples of network topologies that are supported:
- Point-to-Point: The module supports point-to-point topologies, where two devices are connected directly to each other. This can be useful in scenarios where a direct connection is required, such as in a leased line connection.
- Ring Topology: The module supports ring topologies, where devices are connected in a circular fashion. This can be useful in scenarios where redundancy is required, as it provides a backup path in case of a failure.
- Star Topology: The module supports star topologies, where devices are connected to a central hub or switch. This can be useful in scenarios where multiple devices need to be connected to a central point, such as in a local area network (LAN).
- Mesh Topology: The module supports mesh topologies, where devices are connected to each other in a complex web of connections. This can be useful in scenarios where multiple paths are required for redundancy or load balancing.
- Hybrid Topology: The module supports hybrid topologies, which are a combination of two or more of the above topologies. This can be useful in scenarios where a complex network is required, with multiple devices and connections.
Redundant Power Supply
The A900-IMA3G-IMSG Cisco ASR 900 Combo 3G Multirate iMSG and CEM Interface Module is designed to provide high availability and redundancy for network deployments. One of the ways it achieves this is through its redundant power supply feature. Here’s how it works:
The module has two power supply slots, each of which can be populated with a power supply unit (PSU). The two PSUs work together to provide redundant power to the module, ensuring that the module stays powered even if one PSU fails. If one PSU fails, the other PSU takes over, preventing any interruption to the module’s operation.
In addition to providing redundancy, the module’s redundant power supply feature also provides load sharing. The two PSUs work together to share the load of powering the module, ensuring that neither PSU is overloaded and reducing the risk of PSU failure.
The redundant power supply feature is important for ensuring high availability and minimizing downtime in network deployments. By providing redundant power, the module can continue to operate even if one PSU fails, reducing the risk of network downtime and ensuring that critical applications remain available.
Troubleshooting and Diagnostic Tools
The A900-IMA3G-IMSG Cisco ASR 900 Combo 3G Multirate iMSG and CEM Interface Module comes with a range of troubleshooting and diagnostic tools that can help network administrators quickly identify and resolve issues. Here are some of the key tools:
- LED Indicators: The module has LED indicators that can provide information on the status of the module and its various interfaces. For example, the LED indicators can show whether the module is powered on, whether the interfaces are active, and whether there are any errors or warnings.
- Cisco IOS Command-Line Interface: The module can be accessed through the Cisco IOS command-line interface (CLI), which provides a range of diagnostic and troubleshooting tools. The CLI can be used to check the status of interfaces, view error messages, and perform diagnostic tests.
- SNMP Monitoring: The module supports Simple Network Management Protocol (SNMP), which allows network administrators to monitor the status of the module and its interfaces remotely. SNMP can be used to monitor bandwidth usage, error rates, and other key metrics.
- Packet Capture: The module supports packet capture, which allows network administrators to capture and analyze network traffic. This can be useful for troubleshooting issues related to network performance or security.
- Cisco Prime Infrastructure: The module can be managed through Cisco Prime Infrastructure, which provides a range of management and diagnostic tools. Cisco Prime Infrastructure can be used to monitor the status of the module, view performance metrics, and generate reports on network activity.
