The EN4091 pass-thru module provides 14 internal and 14 external 10 Gb Ethernet ports, and it supports 1 Gb and 10 Gb Ethernet signaling for Converged Enhanced Ethernet (CEE), Fibre Channel over Ethernet (FCoE), and other Ethernet-based transport protocols. This pass-thru module does not have an internal Ethernet management interface, but it can provide its vital product data (VPD) to the secure management network in the Chassis Management Module.
