More Information

The Cisco 4-port interface module is a modular expansion card that can be added to certain Cisco routers to provide additional Ethernet interfaces. It is designed to support a variety of interface types, including copper and fiber, and can be used to connect the router to LANs and WANs. The module can support Ethernet, Fast Ethernet, and Gigabit Ethernet speeds, depending on the specific model. It is typically used in enterprise, service provider, and industrial environments to increase the connectivity options of the router. The module is installed in a slot on the router and is connected to the router's main system board using a ribbon cable.

Security Features

The Cisco EHWIC-4ESG 4 Ports Gigabit Ethernet Interface Module offers a range of security features to ensure secure and reliable data transmission. Here are some of the security features:

  • Access Control Lists (ACLs): The EHWIC-4ESG supports the use of ACLs to control access to the network. This feature allows the administrator to define rules to permit or deny traffic based on the source and destination IP addresses, port numbers, and other criteria.
  • Virtual Private Networks (VPNs): The EHWIC-4ESG supports VPNs, which enable secure communication over public networks such as the Internet. VPNs use encryption to protect data and provide secure access to remote users and sites.
  • Network Address Translation (NAT): NAT allows multiple devices on a network to share a single public IP address. The EHWIC-4ESG supports NAT to provide an additional layer of security by hiding the private IP addresses of devices on the network.
  • Port Security: The EHWIC-4ESG supports port security, which allows the administrator to restrict access to a specific port based on the MAC address of the device. This feature prevents unauthorized devices from accessing the network.
  • Link Aggregation Control Protocol (LACP): LACP is used to bundle multiple physical links into a single logical link. The EHWIC-4ESG supports LACP to provide redundancy and improve network performance.
  • Secure Shell (SSH): SSH provides secure remote access to network devices by encrypting all traffic between the client and server. The EHWIC-4ESG supports SSH to ensure secure remote access.
  • Simple Network Management Protocol Version 3 (SNMPv3): SNMPv3 provides secure management of network devices by encrypting SNMP traffic. The EHWIC-4ESG supports SNMPv3 to ensure secure management.
  • DHCP Snooping: DHCP Snooping is used to prevent rogue DHCP servers from assigning IP addresses to devices on the network. The EHWIC-4ESG supports DHCP Snooping to ensure that only authorized DHCP servers are used.

Deployment Scenarios

The Cisco EHWIC-4ESG 4 Ports Gigabit Ethernet Interface Module can be deployed in various scenarios to provide high-speed connectivity and enhance network performance. Here are some deployment scenarios:

  • Branch Office Connectivity: The EHWIC-4ESG can be used in branch offices to provide high-speed connectivity to multiple devices such as servers, workstations, and printers. The module can be installed in a Cisco Integrated Services Router (ISR) to create a branch office network.
  • Campus LAN Extension: The EHWIC-4ESG can be used to extend the campus Local Area Network (LAN) to remote locations. The module can be installed in a Cisco ISR to connect to a Wide Area Network (WAN) service such as MPLS or VPN, and provide high-speed connectivity to remote sites.
  • Data Center Connectivity: The EHWIC-4ESG can be used to provide high-speed connectivity between servers in a data center. The module can be installed in a Cisco ISR or a Cisco Catalyst Switch to connect servers and storage devices, and provide high-speed connectivity within the data center.
  • Virtualization: The EHWIC-4ESG can be used in a virtualized environment to provide network connectivity to virtual machines. The module can be installed in a Cisco ISR or a Cisco Nexus Switch to provide high-speed connectivity to virtual machines and improve network performance in a virtualized environment.
  • Network Monitoring: The EHWIC-4ESG can be used for network monitoring and analysis. The module can be installed in a Cisco ISR to monitor traffic flows and perform network analysis using tools such as NetFlow and Cisco IOS Embedded Packet Capture.
  • Video Surveillance: The EHWIC-4ESG can be used in a video surveillance system to provide high-speed connectivity to IP cameras. The module can be installed in a Cisco ISR or a Cisco Catalyst Switch to connect IP cameras and provide high-speed connectivity for video surveillance.

For all your expansion module needs, we've got you covered with high-performance devices that increase functional capability and ease business processes.

You can talk to any of our staff and consult on what would be the best way forward when getting an expansion module to complement and enhance existing infrastructure, meet your immediate and future needs.

We have hardware level 12 with firmware 3.0 or higher modules that allow for the installation of up to 14 expansion modules below the base module for resilient performance. Expansion modules connect to the base module using USB Type-A connectors. That's not all, we have hardware level 11 and lower that supports up to 9 expansion modules.

With an expansion module, you get additional cartridge storage as well as tape drive capacity. We have expansion modules that contain up to two drives and two power supplies. You can choose to have the expansion module with tape drives and power supply installed so that it makes setup easier from your end. Expansion modules will need a power supply only if you install a tape drive in it. A single power supply can actually power two drives. However, you can add a second power supply for redundancy purposes. Without a tape drive, the expansion module is powered via the USB cable connected to the base module.

Expansion modules require 2U rack space and will be shipped with the necessary mounting hardware used to secure it to the rack.
