License key EXTREME for VDX6740 — enables 8x 10G SFP+ ports (8x10G)

The EXTREME license key for VDX6740 enables eight 10G SFP+ ports on a compatible VDX6740 chassis. This software activation unlocks additional 8x10G SFP+ interfaces to increase 10GbE port density without changing the physical switch. The license is intended for use with a VDX6740 platform where SFP+ transceiver modules are already installed; the key alters software configuration to make the extra ports available for uplinks, server connections, or aggregation links.

Advantages

The license provides a cost-effective way to scale 10GbE connectivity by enabling existing hardware capabilities through software activation. It reduces the need for chassis replacement and minimizes installation time compared with adding new physical switches. Activation preserves existing port layouts while offering predictable expansion of uplink and server-facing interfaces. The solution supports standard 10G SFP+ optics and integrates into current network configurations on the VDX6740 platform.

Suitable for

• Expanding uplink bandwidth to aggregation or core switches
• Increasing server connectivity density in data center racks
• Consolidating multiple 1GbE links into 10GbE uplinks
• Environments where minimizing hardware changes is required

Key specifications

• Enables eight additional 10 Gigabit SFP+ ports
• Software-based license activation for VDX6740 systems
• Operates with standard 10G SFP+ transceiver modules (sold separately)
• Designed for use on compatible VDX6740 chassis with available port slots

How to use

Install compatible 10G SFP+ transceivers in the chassis ports designated for activation. Apply the license key through the VDX6740 management interface according to EXTREME software procedures; the activation typically requires administrator credentials and may prompt for a license file or activation code. After successful activation the newly enabled ports appear in the interface configuration and can be assigned to VLANs, link aggregation groups, or other network profiles as needed. A reboot of management services may be required depending on the platform software version.

Usage recommendations

For reliable 10GbE operation use certified SFP+ modules and compatible fiber or DAC cabling, verify firmware compatibility with the VDX6740 release notes before activation, and perform license activation during a scheduled maintenance window to avoid service disruption.
