What is the maximum throughput and latency of the X670-G2-72x?

The X670-G2-72x delivers 1440 Gbps switching capacity with 1071 Mpps forwarding rate and sub-600 nanosecond latency in cut-through mode. This non-blocking, line-rate performance ensures all 72 ports can operate simultaneously without throughput degradation, making it ideal for latency-sensitive datacenter applications.

Can the X670-G2-72x support both 1Gb and 10Gb connections?

Yes. All 72 SFP+ ports are autosensing and support 1Gb/10Gb dual-speed operation. This flexibility allows mixed-speed deployments using appropriate transceivers, enabling gradual network upgrades and cost-effective integration with existing 1Gb infrastructure while supporting 10Gb connections.

What stacking options are available?

Two of the 72 SFP+ ports are configurable as stacking ports, supporting SummitStack with 80 Gbps, 160 Gbps, and 320 Gbps stacking speeds. This enables flexible stacking configurations with the entire stackable Summit product line, simplifying management of multiple switches as a single logical unit.

What routing capabilities does the X670-G2-72x provide?

The switch supports Layer 3 IPv4/IPv6 routing with 136K IPv4 host addresses, 16K IPv4 LPM entries, 48K IPv6 host addresses, and 8K IPv6 LPM entries. It includes policy-based switching/routing, Provider Bridges, and bidirectional ingress/egress ACLs for sophisticated enterprise network designs.

What are the power and cooling specifications?

The X670-G2-72x features dual hot-swappable 550W AC PSU slots supporting 90-264V AC input with 47-63 Hz frequency. Five rear slots accommodate replaceable fan modules with front-to-back or back-to-front airflow options. Operating temperature range is 0°C to 45°C with 10-90% non-condensing humidity.

Does the X670-G2-72x support timing synchronization?

Yes. The switch includes IEEE 1588 PTP timing with integrated timing output ports: two rear mini-BNC connectors providing 1 PPS frame output and 10 MHz output for connecting Building Integrated Timing Supply (BITS) or GPS timing sources, enabling synchronized operations across distributed networks.

What operating system and software features are included?

The X670-G2-72x runs ExtremeXOS modular OS with full feature set including switching, routing, SDN, Data Center Bridging (DCB), MPLS, and Audio Video Bridging (AVB). It provides 4096 VLANs, 128 load-sharing trunks, 4096 ingress/1024 egress ACL rules, and 8 Kbps bandwidth granularity for QoS.
