Port mapping

The Lenovo Flex System EN4023 10Gb Scalable Switch provides 64 ports that can be configured
as Ethernet ports.
The FlexPort feature allows configuration of specific ports on the Lenovo Flex System EN4023
10Gb Scalable Switch as 10 GbE ports or as 2 Gbps, 4 Gbps, 8 Gbps, or 16 Gbps FC ports,
depending on installed SFP+ transceivers. Therefore, status LEDs may indicate GbE or FC port
function. Refer to
5.0.0 and later.

Configuring the switch
Configuring the switch requires that you first assign an IP address to the switch, which must be
done from the Chassis Management Module (CMM) using the CLI or GUI. After the IP address is
assigned, you then connect to the switch (over SSH) to define configuration settings. To log in to the
CMM, see the Lenovo Flex System Chassis Management Module User's Guide.

Configuring an IP address on the switch using the CLI

1. Install the Lenovo Flex System EN4023 10Gb Scalable Switch in the appropriate bay of the
