WS-X4908-10GE Overview
Cisco Systems is pleased to announce the Cisco Catalyst 4900M Series, a premium extension to the widely deployed Catalyst 4948 Series top of rack Ethernet switches for data center server racks. Optimized for ultimate deployment flexibility, the Catalyst 4900M Series can be deployed for 10/100/1000 server access with 1:1 uplink to downlink oversubscription, mix of 10/100/1000 and 10 GbE servers or all 10GbE servers in the same rack.. The Catalyst 4900M is a 320Gbps, 250Mpps, 2RU fixed configuration switch with 8 fixed wire speed X2 ports on the base unit and 2 optional half card slots for deployment flexibility and investment protection. Low latency, scalable buffer memory and high availability with 1+1 hot swappable AC or DC power supplies and field replaceable fans optimize the Catalyst 4900M for any size of data center.
The Cisco Catalyst 4900M half cards provide a wide variety of combinations of Gigabit Ethernet and 10 Gigabit Ethernet media types. The base unit can accommodate up to two of half cards in any combination.

Frequently Asked Questions (FAQs)
What primary switching capacity does the WS-X4908-10GE line card provide for Cisco Catalyst 4900 series switches? +
The WS-X4908-10GE is a high-performance line card designed to deliver wire-speed 10 Gigabit Ethernet connectivity. It provides eight ports of 10GbE using X2 transceivers, significantly increasing the bandwidth and uplink density for Catalyst 4948-10GE and 4900M chassis, making it an ideal solution for bandwidth-intensive data center aggregation and high-speed core switching tasks.
Which specific transceiver types are supported by the ports on the WS-X4908-10GE module? +
This line card utilizes X2-style form factor transceivers. It supports a variety of Cisco X2 modules, including SR for short-reach multi-mode fiber, LR for long-reach single-mode fiber, and ER for extended-reach requirements. You must ensure that the specific X2 modules selected match your cabling infrastructure and distance requirements to maintain link integrity across your 10GbE fabric.
Can the WS-X4908-10GE be used in environments requiring low-latency traffic processing? +
Yes, this module is engineered to provide non-blocking, line-rate performance, which is critical for low-latency networking environments. By offloading 10GbE switching tasks from the main supervisor, it ensures that packet forwarding remains consistent even under heavy load. It is a robust choice for financial, trading, or virtualization environments where minimized latency and high throughput are essential operational requirements.
How does the WS-X4908-10GE integrate with existing Cisco Catalyst 4900 series deployments? +
Integration is designed to be seamless for compatible chassis. Once installed, the switch automatically recognizes the line card, allowing for immediate configuration via the Cisco IOS command-line interface. Because it is a modular component, it allows network administrators to scale their 10GbE density incrementally without requiring a complete forklift upgrade of the existing Catalyst 4900 core infrastructure.
Does the WS-X4908-10GE support advanced Layer 2 and Layer 3 features? +
The functionality of this module is largely governed by the supervisor engine installed in your Catalyst 4900 chassis. When paired with an appropriate supervisor, the line card supports full Layer 2 switching as well as hardware-accelerated Layer 3 routing protocols. It maintains compatibility with standard enterprise feature sets, including VLAN trunking, QoS prioritization, and advanced security access control lists.
What is the recommended power management strategy when adding a WS-X4908-10GE to a rack? +
Adding a high-performance 10GbE line card increases the power draw of your chassis. Before deployment, confirm that your current power supply units (PSUs) have sufficient capacity to handle the additional load of the module plus the populated X2 transceivers. We recommend checking the system power budget through the Cisco CLI or planning documentation to ensure sustained, stable operation under peak traffic conditions.
How should I maintain or clean the fiber optic interfaces on the WS-X4908-10GE? +
Proper maintenance of the X2 ports is vital for 10GbE performance. Use industry-standard fiber optic cleaning kits to inspect and clean the end-faces of your transceivers and patch cords. Avoid touching the optical surfaces, and always keep dust caps on ports that are not currently in use to prevent debris accumulation that could degrade signal quality or result in link flaps.
Is the WS-X4908-10GE suitable for high-density server farm uplinks? +
Absolutely. This module is purpose-built for high-density environments where multiple servers require 10GbE connectivity to a core switch. By providing eight 10GbE ports in a compact form factor, it significantly reduces cabling complexity and footprint compared to lower-speed aggregation methods. It is a highly effective tool for centralizing traffic from virtualized host clusters in enterprise data centers.
How can I request a bulk quote for multiple WS-X4908-10GE units for an upcoming project? +
