The WS-F4531 is a great investment for our network. It ensures high-speed data transfer and reliable connectivity across all devices.
The WS-F4531 has been performing flawlessly. It provides excellent speed and ensures stable connectivity for our network.
The WS-F4531 is reliable and fast. It handles our network traffic efficiently, ensuring smooth operations with no interruptions.
The WS-F4531 integrates seamlessly and provides stable, high-speed performance. It has been a valuable asset to our network.
We rely on the WS-F4531 for its exceptional reliability. It ensures fast, stable connectivity and works well with our existing infrastructure.
The WS-F4531 is a 24-port 1 Gbps line card for Cisco Catalyst 4500 series with integrated IEEE 802.3af PoE support, delivering up to 15.4 W per port at wire-speed switching.
The WS-F4531 is compatible with Cisco Catalyst 4503, 4506, 4507R+E and 4510R+E chassis when used with an appropriate Supervisor Engine (E or XE) module.
The WS-F4531 provides 24 RJ45 ports, each supporting IEEE 802.3af PoE at up to 15.4 W per port for IP phones, wireless access points and other powered devices.
The WS-F4531 delivers up to 32 Gbps of non-blocking switching capacity and can forward up to 26 million packets per second at line rate across all 24 ports.
The WS-F4531 operates under Cisco IOS Software on Catalyst 4500-series Supervisor Engines; it does not support IOS XE directly on the line card.
Power down the chassis, slide the WS-F4531 into an available line-card slot until the ejector handles engage, reconnect power and boot the Supervisor to detect the new module.
The WS-F4531 supplies a total PoE budget of up to 370 W, dynamically allocating up to 15.4 W to each of the 24 ports per IEEE 802.3af.
No. The WS-F4531 supports only IEEE 802.3af PoE at 15.4 W per port and does not provide IEEE 802.3at or Cisco UPOE power levels.
The WS-F4531 has an MTBF of approximately 300,000 hours under standard operating conditions, ensuring high availability in enterprise deployments.
No separate license is needed for basic IEEE 802.3af PoE. Advanced features such as QoS, ACLs and multicast require the feature license on the Supervisor Engine.
Yes. When paired with a feature-licensed Supervisor, the WS-F4531 supports granular QoS, rate limiting, class-based ACLs and multicast optimization.
The WS-F4531 does not support physical stacking; however, it benefits from Virtual Switching System (VSS) when used with VSS-capable Supervisor Engines.
The WS-F4531 operates at 32°F to 104°F (0°C to 40°C), 10–90% non-condensing relative humidity and a maximum altitude of 5,000 ft (1,524 m).
The WS-F4531 includes a 1-year limited hardware warranty. Cisco SMARTnet or Cisco Solution Support contracts extend coverage for parts replacement and technical assistance.
Use IOS commands such as "show power inline" and "show module" to verify PoE status, power draw and port diagnostics; check cabling and powered-device compatibility.
Cisco WS-F4531 line cards are available through Cisco’s authorized resellers, distribution partners or directly via Cisco’s online ordering portal.
