Extreme X670V-48X product specifications
Product Overview
The Extreme X670V-48X is a 1 RU, high-density Layer 3 switch from the Summit X670 Series, purpose-built for data-center leaf and top-of-rack deployments where 10 GbE server access and 40 GbE fabric uplinks must coexist in a compact footprint. Combining 48 dual-speed 1/10 GbE SFP+ ports with four native 40 GbE QSFP+ uplinks, Extreme X670V-48X delivers an aggregate 1.28 Tbps switching capacity at 952 Mpps forwarding rate, ensuring that east-west virtual-machine traffic never becomes a bottleneck. The device runs ExtremeXOS, a modular operating system that supports MLAG, VXLAN, and MPLS, so network architects can collapse access and aggregation tiers without sacrificing policy enforcement or traffic visibility. Hot-swappable redundant AC or DC power supplies, reversible airflow options, and a carrier-grade temperature range make Extreme X670V-48X equally at home in colocation cages, telco central offices, or high-performance compute clusters.

Main features and advantages
Hardware-accelerated Layer 3 forwarding keeps control-plane resources free, while 2 048 ingress ACLs and 1 024 egress ACLs per device enable micro-segmentation for zero-trust security models. The X670V-48X supports ISSU, hitless failover, and sFlow-based telemetry, so operators can upgrade firmware or redirect traffic without dropping packets. Eight quality-of-service queues per port, combined with 2 048 programmable meters, guarantee that storage, voice and video traffic each receive deterministic bandwidth. With front-to-back or back-to-front airflow and tool-less fan tray removal, the switch adapts to hot-aisle/cold-aisle designs while keeping acoustic noise under 69 dB(A). Finally, the VIM4-40G4X module can be field-installed in minutes, turning the X670V-48X from a simple top-of-rack switch into a 40 GbE aggregation node without additional rack space.

Application fields
Hyperscale cloud providers deploy X670V-48X as leaf switches in 10 GbE server racks, using the four 40 GbE uplinks to build non-blocking spine planes that scale beyond 1,000 nodes. Financial exchanges leverage the sub-microsecond latency to feed market-data servers and FPGA-based trading engines, while the extensive ACL table enforces regulatory segmentation. In university research clusters, the switch’s support for RDMA over Converged Ethernet accelerates MPI workloads, and its IPv6 LPM table scales to 8 K prefixes, future-proofing campus backbones. Telco edge data centers adopt X670V-48X because the DC power option aligns with −48 V plant standards, enabling 5G user-plane functions to coexist with MEC servers in a single rack.

Installation and maintenance
Preparations before installation: Verify that the facility can supply the selected AC (90–264 V) or DC (-35 to -75 V) input, and mount the X670V-48X in a 19-inch rack with at least 5 cm clearance at the front for airflow. Label uplink and downlink cables to match the intended port map, and pre-load the desired ExtremeXOS image onto a USB drive for zero-touch provisioning.

Maintenance Suggestions: Inspect fan trays quarterly for dust accumulation; replace any module when RPM deviates by more than 10 %. Schedule firmware upgrades during maintenance windows, leveraging ISSU to preserve traffic forwarding. Retain a spare 450 W PSU on-site, as the X670V-48X supports hitless replacement. Log files and core dumps can be mirrored to an external server to simplify root-cause analysis.
