Does it support MACsec encryption?

No MACsec support on copper or fiber ports, as per Extreme Networks specs. It focuses on high-performance Layer 3 routing with large tables (294K MAC, 256K IPv4 routes) and ACLs (8K ingress), suitable for non-encrypted aggregation/core roles.

What is the power and cooling configuration?

Ships with 2 x AC power supply modules and 6 x fan modules, all back-to-front airflow. Max consumption is 398W at full 100% traffic load with fans high, dissipating 1359 BTU/hr. Redundancy ensures reliability in 1U rackmount setups.

What are the switching performance specs?

Provides 2.4Tbps non-blocking capacity, 294K MAC table, 256K IPv4 routes, 131K IPv6 routes, 4K VLANs, and 8 QoS queues per port. Supports 8K ingress/1K egress ACLs, ideal for high-scale enterprise core with wire-speed performance.

Is rack mounting hardware included?

Yes, a 4-post rack mount kit is included for standard 19-inch EIA racks. The 1U form factor with back-to-front airflow and front system LEDs simplifies installation and monitoring in data centers.

What use cases is this switch designed for?

Purpose-built for aggregation/core in data centers, supporting server farms via 48x10G copper and 100G uplinks. Universal platform enables Extreme OS for secure segmentation, east-west traffic, and AI workloads with flexible policy capabilities.
