What are the port configurations of the EN4093 switch?

It includes 42 internal 10 Gb Ethernet ports (3 per compute node with full licensing), 14 external SFP/SFP+ ports, and 2 QSFP+ ports. Base licenses cover 24x 10 GbE ports assignable internally/externally, supporting media like SR/LR transceivers and DAC/AOC cables for 10/40 GbE.

Does it support Layer 3 switching and SDN?

Yes, it offers full Layer 2/3 switching and is SDN-ready with OpenFlow support. Additional features include CEE, DCB, FCoE transit, and up to 64x 10 Gb connections for advanced routing in datacenter fabrics.

How many switches can be stacked?

Up to 8 switches can be stacked, sharing one IP address and management interface. This simplifies administration in multi-chassis Flex System deployments while maintaining browser-based access.

What is the form factor and compatibility?

It's a Flex System embedded I/O module for Enterprise Chassis I/O bays. Compatible with compute nodes using CN4058S adapters for up to 48 vNICs per node pair, ideal for high-density virtualization.

What management options are available?

Features single IP for stacked units, browser-based interface, and industry-standard CLI/SNMP. Internal GbE ports connect to chassis management module, with external RJ-45 and mini-USB options.

What is the power consumption?

Typical power consumption is 141W, supporting efficient operation in dense blade environments. Non-blocking architecture ensures wire-speed 1.28 Tbps throughput without performance degradation.
