Calability and Upgrade Options

The C1861E-UC-4FXO-K9 Cisco 1861 2 Ports 10/100 Wired Router is a legacy router that is no longer being produced and supported by Cisco. Therefore, it may not have the same level of scalability and upgrade options as newer router models.


  • The C1861E-UC-4FXO-K9 router has a limited number of ports and is designed for small to medium-sized businesses.
  • It has 2 10/100 Ethernet ports and 4 FXO ports for connecting to analog telephone lines, which may not be sufficient for larger network deployments.
  • It also has limited memory and processing power, which may limit its ability to handle large amounts of traffic.

Upgrade options:

  • As this router is no longer being produced and supported by Cisco, there may be limited upgrade options available.
  • Software updates and security patches may no longer be available for this router.
  • It may not be compatible with newer technologies and features that are available on newer router models.

It is important to note that the C1861E-UC-4FXO-K9 router is a legacy model and may not have the same level of scalability and upgrade options as newer router models. If you are looking for a more scalable and upgradeable router, it is recommended to consider newer models from Cisco or other vendors that are designed for modern networks.

Setting Up and Configuring the C1861E-UC-4FXO-K9

Setting up and configuring the C1861E-UC-4FXO-K9 Cisco 1861 2 Ports 10/100 Wired Router involves several steps, including:

Hardware setup

  • Unpack the router and connect the power cord to an electrical outlet.
  • Connect the router to a computer or laptop using the console cable.
  • Connect the router's Ethernet ports to your LAN devices.

Configuring basic settings

  • Open a terminal emulation software (such as Putty) and configure the serial connection settings to match the router's console port settings (baud rate: 9600, data bits: 8, parity: none, stop bits: 1, flow control: none).
  • Press the Enter key to access the router's command-line interface (CLI).
  • Use the "enable" command to enter privileged mode, and then set a new password for the "enable" mode using the "configure terminal" command.
  • Use the "hostname" command to set a new hostname for the router.
  • Use the "interface" command to configure the router's LAN interfaces.
  • Use the "ip address" command to assign IP addresses to the router's interfaces.

Configuring routing

  • Use the "ip routing" command to enable IP routing on the router.
  • Use the "ip route" command to configure static routes on the router.
  • Use the "router eigrp" command to configure EIGRP routing on the router.

Configuring security

  • Use the "access-list" command to configure access control lists on the router.
  • Use the "crypto key generate rsa" command to generate an RSA key pair for the router.
  • Use the "line vty" command to configure the router's virtual terminal interfaces.

Saving the configuration

  • Use the "copy running-config startup-config" command to save the current configuration to the router's non-volatile memory (NVRAM).

Once the router is set up and configured, you can use the "show" commands to verify the router's configuration and troubleshoot any issues. It's also recommended to regularly back up your configurations to avoid losing any important information in case of a failure.

  • About Refurbished Products

    Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

    Routers lead the line as the first line of network security in homes and offices. It prevents intrusion into a network while creating a firewall to provide the highest level of security on several network types. They are the best ways of keeping computer systems, network systems, and information contained in them safe from intrusion.

    A router is designed to be more capable than several other network devices such as hubs or switches that can only carry out basic network functions. For instance, a hub only transfers data between network devices without analyzing or doing anything with those data. On the other hand, routers are able to analyze data sent between network devices. They can change the packaging of such data and send it over to a different network.

    Routers are the perfect devices to share an internet connection between multiple computers in home networks. A router typically connects to the modem using a network cable. Router networking occurs via a WAN port or the internet. There are also wireless routers that connect to devices using different wireless standards.

    Important Features

    Multi-core Processor

    The hardware inside these routers allows them to cope with several network use at the same time. Many of these routers come with dual-core and quad-core processors. These processor options allow them to handle lots of data more effectively. Users can use their Wi-Fi routers for activities such as video streaming, online gaming, data backups, and more. Even while carrying out those operations, the routers perform at the highest levels.

    Multi-band options

    Users will get routers that broadcast wireless signals over two frequencies (for dual-band) or more (for tri-band and others). These routers run at frequencies that can cover a wide expanse of area. They are not congested and are perfect for office buildings, homes, and large enterprises. Clients will find routers that emit their signals between 2.4 GHz and 5 GHz.

    Built-in Security Features

    These router networking devices also come with security features such as device quarantine, firmware updates, automatic updates, and more. The features allow them to provide network-level protection against attacks. With these features, cyber criminals will be unable to infiltrate home networks.

    Types of Routers

    There are several types of routers that users can benefit from. Some of them include:

    • Core Routers. These are the types used by Internet Service Providers. They are the fastest and most powerful types. They sit at the center of the internet and forward data through the main fiber Optics.
    • Wireless Routers. These work in a similar manner as a home or business LAN. However, they give room for better mobility for laptops, tablets, and other portable devices. These types offer transmission over short distances.
    • Enterprise Routers. These are the types employed by large companies. Organizations use enterprise routers to connect their networks to these core routers.
    • Branch Routers. These types connect an enterprise's remote offices to its Wide Area Network (WAN). They come with improved features such as wireless LAN management, time-division multiplexing, WAN acceleration, and more.
    • Edge Routers. These are the most commonly used types in homes and small businesses. They are low-capacity devices that connect to the public internet or private WAN, or external LAN.
    • Logical Routers. They function similarly to hardware to create several network routes.
