What ports does the IBM EN4093 switch provide?

It offers 42 internal full-duplex 10Gb Ethernet ports for Flex System compute nodes and external 14 SFP+ 10Gb ports plus 2 QSFP+ 40Gb ports (splittable to 8x SFP+). Base license enables 14 internal and 10 external ports, scalable via FoD upgrades to full 64x 10Gb capacity.

Is this switch compatible with Flex System chassis?

Yes, it installs directly in I/O module bays of Flex System Enterprise Chassis. Supports up to 28 network adapters per chassis and configurations like four switches with CN4058S adapters for 48 vNICs, ideal for high-density virtualization.

What switching features are supported?

Layer 2/3 Ethernet with cut-through method, VLANs, STP, LAG/vLAG, QoS, OpenFlow, VMready, UFP, FCoE transit, IPv4/IPv6 routing, VRRP, OSPF v3, and up to 128 static IPv6 routes for advanced traffic management.

Can it support 40Gb uplinks?

Yes, 2 QSFP+ external ports handle 40Gb Ethernet with SR4/LR4/BiDi transceivers, DAC/AOC cables, or breakout to 4x 10Gb SFP+. Internal ports fixed at 10Gb (1/10 Gbps flexible), enabling 10/40Gb infrastructure migration.

What management options are available?

Lenovo Networking OS provides multiple interfaces for configuration, including IPv4/IPv6 management, stacking, Switch Partitioning, Edge Virtual Bridging, and SDN-ready OpenFlow/easy connect modes for simplified virtualized network control.

What compliance standards does it meet?

Certified RoHS and WEEE compliant. Designed for enterprise reliability with features like Layer 2 failover and Hot Links, assuming chassis base warranty for physical specs: 30mm height, rack-mountable in Flex System.
