Introduction to the 24 Ports Switch
The SM-ES3G-24-P Cisco 24 Ports Managed Switch Module is a powerful and versatile networking device that is designed to provide enterprise-grade LAN connectivity for small and medium-sized businesses. It is a plug-in module that can be easily installed into the Cisco ISR G3 routers to provide additional Ethernet ports and advanced switching capabilities.
The switch module has 24 Ethernet ports that support 10/100/1000Mbps speeds, providing high-speed connectivity for a variety of devices such as servers, workstations, and IP phones. It also supports advanced features such as Quality of Service (QoS), VLANs, and Link Aggregation Control Protocol (LACP) for improved network performance and flexibility.
QoS allows the network administrator to prioritize different types of traffic, such as voice and video, to ensure that critical applications receive the bandwidth they need. VLANs allow the creation of virtual networks within the physical network, providing better security and isolation for different departments or groups. LACP allows the bundling of multiple physical links into a single logical link, increasing bandwidth and providing redundancy.
The SM-ES3G-24-P also has a web-based interface for easy configuration and management, allowing the network administrator to easily set up and monitor the switch module from any web browser. It also supports SNMP and syslog for remote management and monitoring.
Power Options and Redundancy
The SM-ES3G-24-P Cisco 24 Ports Managed Switch Module has several power options and redundancy features to ensure that it is always available and functioning correctly.
One of the power options for the SM-ES3G-24-P is to use the internal power supply of the Cisco ISR G3 router that it is installed in. The router's power supply is able to provide enough power to the switch module. This is known as inline power, as the switch module uses the same power source as the router.
Another power option is to use an external power supply that can be connected to the switch module through an AC/DC power adapter. This provides an additional power source for the switch module and can be used as a backup power source in case of a failure in the internal power supply.
The SM-ES3G-24-P also supports power redundancy through the use of the Cisco Power over Ethernet (PoE) module. This module can provide power to the switch module through the Ethernet cables, eliminating the need for an external power supply. This also allows for redundancy, as the PoE module can provide power to the switch module even if the internal power supply fails.
Redundancy can also be provided at the link level, by using the Link Aggregation Control Protocol (LACP) feature. This allows the bundling of multiple physical links into a single logical link, increasing bandwidth and providing redundancy. If one of the physical links fails, the other links will continue to provide connectivity, minimizing downtime and interruption of service.
Security and management
The SM-ES3G-24-P Cisco 24 Ports Managed Switch Module has several security and management features to ensure that your network is secure and easy to manage.
One of the security features of the SM-ES3G-24-P is the ability to create and configure virtual LANs (VLANs). This allows the creation of virtual networks within the physical network, providing better security and isolation for different departments or groups. This feature allows you to segment your network, creating separate broadcast domains and security zones, which helps to prevent unauthorized access and broadcast storms.
Another security feature is the support for Access Control Lists (ACLs). This feature allows the administrator to define specific rules for controlling access to the network based on criteria such as IP address, port number, or protocol. This helps to prevent unauthorized access and protect against network-based attacks.
The SM-ES3G-24-P also supports Quality of Service (QoS), which allows the network administrator to prioritize different types of traffic, such as voice and video, to ensure that critical applications receive the bandwidth they need. This feature helps to ensure that important network traffic is given priority over less important traffic, reducing the chances of congestion and improving network performance.
In terms of management, the SM-ES3G-24-P has a web-based interface for easy configuration and management, allowing the network administrator to easily set up and monitor the switch module from any web browser. It also supports SNMP and syslog for remote management and monitoring. This allows you to monitor the switch module's performance, view logs, and receive alerts in case of any issues, ensuring that your network is always running smoothly.

About Refurbished Products
Different Types of Switches
Networking switches vary widely depending on the number of devices they can support, network bandwidth/speed, and form factor. Switches for small offices will have anything between 4 and 8 ports and can fit on a desk. For larger office network implementation, switches may have 24 ports, 48 ports, 96 ports, and 128 ports and are rack-mountable between 1U and 4U. Switches come in different types depending on the network speed and tasks they support. These include 40/100 Gbps, 10 Gigabit (up to 10000 Mbps), Gigabit Ethernet (up to 1000 Mbps), Power over Ethernet, and Fast Ethernet (10/100 Mbps).
The unmanaged switches offer fixed configuration on a plug-and-play basis. It is the most basic switch and there are a few choices in the market. These switches are affordable, but the basic features make them inappropriate for enterprise applications.
The number of features and level of functionality improves with managed switches, making them ideal for enterprise and business applications. These switches are built with the command-line interface for ease of configuration. Equally, they support SNMP agents that come in handy when troubleshooting network issues.
The security on managed switches is better and will protect different types of traffic. Other features include support for virtual LANs, IP routing, and quality of service settings. Managed switches are more expensive compared to all other types of switches.
Smart switches refer to switches that possess more features than those of unmanaged switches but do not have the full features of managed switches. Smart switches are more cost-effective than managed switches.
Some of the limitations of the smart switches are a lack of telnet access support, Web GUIs, and a lack of many features for VLANs. They are affordable compared to a fully managed switch and are suitable for a smaller computer network.
Modular switches allow the addition of expansion modules as the network expands. The expansion modules allow for more networked devices but are application-specific. They may include wireless access points, firewalls, or network analysis tools. The flexibility of a modular networking switch comes at a higher cost.
