What is the switching performance?

The switch delivers 960 Gbps bandwidth and 714 Mpps forwarding rate with less than 1 microsecond latency for 64-byte packets. It supports jumbo frames up to 9216 bytes and both store-and-forward plus cut-through switching modes for optimal performance.

Does it support VLANs and link aggregation?

Yes, supports 4,094 VLANs (port, protocol, IEEE 802.1Q) and 128 load-sharing trunks with up to 8 members per trunk. This enables robust network segmentation and resilient high-bandwidth uplinks for enterprise environments.

What power options are available?

Dual hot-swappable AC power supplies with 100–240V~, 50/60Hz, 2.5A input ratings. Maximum power consumption is 330W (1126 BTU/h), with input current 2.25A at 100V or 0.9A at 240V, ensuring redundancy and efficiency.

What are the physical dimensions and weight?

1RU rack-mountable form factor: 1.57 inches (4.0 cm) height, 17.3 inches (44 cm) width, approximately 19 inches depth. Weight is 18.78 lb (8.52 kg) including power supplies and fan modules, with front-to-back airflow.

What management interfaces are included?

Out-of-band 10/100/1000 Mbps Ethernet management port and RS-232 serial console port. Runs ExtremeXOS OS for CLI, SNMP v1/v2c/v3 management, providing unified operations across Extreme Networks switches.
