System compatibility
XBR-VDX6740-24-R belongs to Extreme VDX6740 series leaf switch family, 24-port PoD licensed variant, R stands for port-side exhaust airflow. Compatible with standard 10G SFP+ and 40G QSFP+ transceivers. Support VCS fabric virtualization. FlexPort enables FCoE storage convergence. End-of-sale hardware platform, widely used for legacy data center leaf-spine network renovation and spare replacement.
Function
XBR-VDX6740-24-R is 1U compact high-performance data center leaf switch manufactured by Extreme Networks. It comes with 24 active 10G SFP+ ports for server access, 4×40G QSFP+ uplink ports for interconnection to spine switches. VCS fabric merges multiple VDX switches as one logical device, simplifies deployment and maintenance. FlexPort supports FCoE to converge LAN and storage traffic on single network infrastructure. Supports full IPv4/IPv6 routing, DCB lossless ethernet, 802.1X authentication, VLAN segmentation and hardware QoS. Dual redundant hot-swap PSU and fans ensure high availability for critical data center workloads. Widely deployed for virtualization, storage convergence and enterprise data center spare replacement.
Installation
Follow ESD protection procedure. Mount switch to standard 19-inch 1U rack. Connect AC power cords to both power supplies. Insert SFP+/QSFP+ transceivers for server access and uplink connection. Access serial console port for initial NOS configuration, set VCS fabric, VLAN, routing and QoS policy. Verify fabric formation and port connectivity after power-up. Activate extra PoD license to unlock additional 10G ports if required.

Feature
Original Extreme Networks XBR-VDX6740-24-R datacenter leaf switch,1U,24 active 10G SFP+ +4×40G QSFP+,VCS virtual fabric,FCoE FlexPort,port-side exhaust airflow,NOS OS,support hot-swappable redundant power and fan. This spare unit is used for legacy data center leaf network maintenance and hardware replacement.
Diagnostic
Switch boot failure: Check AC power input and cable, inspect redundant power module installation status. Port link down: Confirm SFP+/QSFP+ transceiver compatibility, inspect fiber end face and cable quality. VCS fabric split: Verify inter-switch 40G links, match NOS firmware version on all fabric nodes. Inactive ports: This is 24P PoD model, extra ports require additional license activation. Overheat alarm: Check fan module working condition and rack airflow.
