ExtremeSwitching 5520-VIM-4X 4-Port SFP+ Versatile Interface Module

1. Product Overview

The ExtremeSwitching 5520-VIM-4X is a high-performance 4-port SFP+ Versatile Interface Module designed for the Extreme 5520 Series universal switches. It provides flexible and scalable uplink connectivity, supporting both 1Gb and 10Gb Ethernet speeds. This module is ideal for enterprises seeking to enhance their network aggregation or edge switching capabilities with reliable, high-speed fiber connections.

2. Key Features

• Four SFP+ ports supporting 1Gb and 10Gb Ethernet
• Hot-swappable design for easy installation and maintenance
• Compatible with all Extreme 5520 Series switch models
• Designed for high-density data center and enterprise environments
• Enables flexible uplink options for stacking or fabric connectivity

3. Technology & Standards

The 5520-VIM-4X complies with industry-standard protocols including IEEE 802.3ae for 10GBASE-X and IEEE 802.3ab for 1000BASE-X. It supports both short-range and long-range optical transceivers, making it suitable for diverse deployment scenarios.

4. How It Works

The module inserts into the VIM slot of a compatible Extreme 5520 switch. Once installed, it automatically registers with the switch operating system (EXOS or VOSS) and provides four additional fiber ports. These ports can be configured as uplinks, stacking ports, or part of a fabric network, depending on the OS and network design.

5. Applications

The 5520-VIM-4X is widely used in:

• Data center top-of-rack switching
• Enterprise campus aggregation
• High-performance computing clusters
• Cloud infrastructure uplinks
• Media and broadcasting networks

9. Frequently Asked Questions

Q: Is the 5520-VIM-4X compatible with non-Extreme switches?
A: No, it is designed exclusively for the Extreme 5520 Series switches.

Q: Does it support 25Gb speeds?
A: No, for 25Gb support, consider the 5520-VIM-4YE model.

Q: Is a license required to use this module?
A: No, the module is hardware-based and does not require a separate license for basic functionality.

10. Precautions

• Ensure the switch is powered off or the VIM slot is supported for hot-swap before installation.
• Use only Extreme-certified SFP+ transceivers for optimal performance and support.
• Do not mix airflow directions between modules and power supplies in the same chassis.
• Verify compatibility with your switch OS version (EXOS or VOSS).
