Cisco 4 x 1G/10G Network Module

The Cisco 4 x 1G/10G Network Module is engineered to deliver scalable, high-speed connectivity for modern data centers and enterprise networks. Built on Cisco’s renowned engineering standards, this module blends 1G and 10G performance in a compact, plug-and-play form factor, empowering IT teams to upgrade network performance without overhauling existing infrastructure. With 10GBase-X technology at its core, it provides multi-gigabit uplinks and flexible per-port options that help optimize cabling, power usage, and overall network efficiency. Designed to fit Cisco switch and router platforms that support modular network modules, this solution expands port density and bandwidth precisely where it’s needed. Whether you’re provisioning server-to-switch uplinks, storage networking, or high-density access connectivity, this module delivers dependable throughput, low latency, and the reliability you expect from Cisco hardware.

• Flexible port configuration and auto-negotiation: The 4 x 1G/10G network module provides per-port speed flexibility, supporting auto-negotiation and compatibility with both 1G and 10G transceivers. This enables a phased approach to upgrading from 1G to 10G without ripping out existing cabling or chassis components. You can deploy cost-effective 1G connections for access-layer devices and reserve higher-performance 10G uplinks for core servers, storage arrays, and virtualization hosts. The result is a future-ready solution that scales with network growth, minimizes downtime, and reduces the need for forklift upgrades. With consistent per-port behavior across the module, administration becomes simpler and more predictable in data centers, campuses, and branch offices.
• High performance and low latency: Leveraging 10GBase-X technology, this module delivers high-throughput links with low latency to accelerate data-intensive workloads. It’s engineered to handle burst traffic, with hardware-assisted buffering and flow-control optimization that minimizes congestion and jitter. In practical terms, this translates to faster VM migrations, snappier database access, improved application responsiveness, and smoother real-time analytics. Operators will appreciate reliable performance under load, predictable latency for latency-sensitive applications, and improved quality of service (QoS) when routing traffic between virtualized environments, cloud services, and on-premises resources.
• Easy installation and hot-swappable design: The 4 x 1G/10G module is built for quick, low-risk deployment in Cisco switches and routers that support modular network modules. It features secure latching and alignment aids to ensure proper seating, with a simple insert-and-click installation. In hot-swappable configurations supported by compatible chassis, you can replace or upgrade modules without powering down the host device, reducing maintenance windows and downtime. The rugged construction and tested interoperability with Cisco backplanes contribute to long-term reliability in 24/7 operation, even in challenging data-center environments.
• Scalability for dense networks and simplified cabling: With four ports capable of 1G/10G operation, this module dramatically increases port density without expanding the chassis footprint. The compact design reduces cable clutter while enabling more uplinks, server connections, or storage pathways within a single line card. When paired with the appropriate transceivers and fiber cabling, it supports multi-gigabit aggregation, link aggregation (LACP), and high-bandwidth storage networks. The result is a scalable solution that grows with your data center, supports virtualization and containerized workloads, and lowers total cost of ownership by simplifying cabling, reducing power draw, and easing cooling requirements.
• Security, reliability, and network-wide QoS: The module adheres to Cisco-grade reliability standards, offering robust QoS capabilities, VLAN tagging, and traffic shaping at the edge. By isolating traffic onto dedicated 1G/10G uplinks and applying appropriate access controls, it helps protect critical workloads while preserving predictable performance. The hardware is built for enterprise reliability, delivering consistent performance under heavy loads, excellent error detection, and resilient operation that underpins scalable, cloud-enabled architectures. This combination of security, reliability, and performance makes it a solid foundation for demanding business applications and multi-site deployments.

how to install Cisco 4 x 1G/10G Network Module

• Prepare the chassis and review the device’s maintenance guidelines. Ensure you have the correct slot type and compatible transceivers ready for your 1G/10G deployment.
• Power down the host device if required by your chassis documentation, or confirm hot-swappable capability for your model to minimize downtime.
• If replacing an existing module, release the latch and remove the current module carefully, placing it on a non-static surface.
• Align the Cisco 4 x 1G/10G Network Module with the slot guides, slide it into the backplane until it seats firmly, and engage the latch until you hear a secure click.
• Attach the appropriate fiber cables to the SFP/SFP+ ports, power on (or confirm automatic enrollment), and verify port status via the switch’s management interface to ensure all links come up at the expected speeds and duplex settings.

Frequently asked questions

Q: What speeds does this module support?

A: This module supports 1G and 10G per port, using compatible SFP or SFP+ transceivers. Each port negotiates the highest supported speed based on the connected device and transceiver, enabling flexible scaling from 1G access links to 10G uplinks.

Q: Is this module compatible with Cisco Catalyst and Nexus switches?

A: Yes. The Cisco 4 x 1G/10G Network Module is designed for Cisco switches and routers that support modular network modules. Always consult the device’s compatibility matrix to confirm exact model support and required transceivers for your platform.

Q: Can I mix 1G and 10G on the same module?

A: Yes. Each port negotiates independently, allowing a mix of 1G and 10G connections based on transceiver availability and network design requirements.

Q: Is the module hot-swappable?

A: In supported Cisco chassis, the module is hot-swappable, enabling replacement or upgrades without powering down the entire system. Follow proper ESD procedures and vendor guidelines during installation or replacement.

Q: Does this module require external power?

A: No. The module draws power from the switch or router backplane, eliminating the need for a separate power supply and simplifying deployment in dense network environments.
