The WS-X4920-GB-RJ45= is a Cisco 20-port wire-speed 10/100/1000 (RJ-45) expansion module designed specifically for switch expansion. This half-card module offers 20 separate ports, each adhering to the standard RJ-45 connection type and capable of operating at 10/100/1000 Mbps speeds. It delivers robust network performance and reliability, suitable for environments requiring expanded connectivity without compromising on speed or flexibility.
Each of the 20 ports supports auto-negotiation, enabling devices to connect and determine the best possible transmission speed. The module ensures wire-speed forwarding, offering non-blocking connectivity across all ports, which is critical for reducing bottlenecks and enhancing network performance. The expansion module is built to be compatible with certain Cisco Catalyst switch families, delivering seamless switch port expansion and adding future-proofing to the network infrastructure.
This module occupies half the space of a traditional expansion card, making it a more compact solution for environments where space efficiency is vital. With full support for both Layer 2 and Layer 3 switching, the module helps offer flexibility in network configuration. Moreover, the unit operates efficiently even in highly active network environments due to its strong ability to handle multiple connection speeds and forwarding tasks concurrently. These attributes make it a resourceful addition to an enterprise networking setup, especially those requiring a scalable and easily adjustable approach to switch expansion.
