What is the switching capacity and latency?

Switching capacity is 336 Gbps with 250 Mpps throughput. Latency: <5 µs (1GE), <3 µs (10GE), <1.2 µs (40GE) for 64-byte packets. Cut-through architecture ensures low delay for demanding apps.

Does it support stacking?

Yes, IRF stacking up to 9 switches for virtualized L2 switching and L3 forwarding. This creates a single logical device with full IPv4/IPv6 dual stack, simplifying management in multi-rack setups.

What are the power specifications?

Dual redundant hot-pluggable power supplies with reversible airflow. Consumption: 96 W (dual AC); max 327.6 BTU/hr. Voltage: 100-240 VAC or -48 to -60 VDC depending on PSU.

What management features are available?

Supports IMC, CLI, out-of-band management, SNMP, Telnet, FTP. Protocols include OpenFlow, NETCONF, full L2/L3. Equipped with 2 GB SDRAM, 1 GB flash, 8 MB packet buffer.

What is the form factor and environment specs?

1U rack-mountable. Operating humidity: 10-90% noncondensing. Designed for data center top-of-rack with high availability features like redundant PSUs.
