What is the switching performance?

Switching capacity is 104 Gbps with 77.4 Mpps forwarding rate, supporting 16K MAC addresses, 4092 VLANs, 9216-byte jumbo frames, 128 trunks (8 members max), 8 QoS queues per port, and latency under 4 microseconds for 64-byte packets.

Does it support stacking?

Yes, SummitStack-V via two 10Gb ports allows stacking up to 8 switches at 40Gbps per unit using standard 10GbE cabling/optics up to 40km. This provides high-speed, resilient logical management.

What management features are available?

Runs ExtremeXOS Modular OS with ExtremeCloud IQ and Site Engine for cloud-based management. Supports Layer 2/3 IPv4/IPv6 routing, IEEE 802.1 AVB, role-based policy, ACLs, and bandwidth control for comprehensive network oversight.

What is the PoE capability?

12 PoE+ ports provide up to 200W total budget at 30W per port, ideal for powering IP cameras, wireless APs, or VoIP phones directly over Ethernet, simplifying installations without separate power supplies.

What form factor and power options?

1U rack-mountable with fixed internal AC power supply and rear RPS connector for redundancy. Dimensions: 1.73" H x 12.01" W x 10.28" D, suitable for standard 19" racks in enterprise data centers.
