Step 4: Configure Flex switches

Configure the Flex switches in each chassis.

Before you begin

Ensure that all appropriate ports are enabled, including external ports from the Flex switch to the top-of-rack switch and internal ports to the CMM.

If the Flex switches are set up to get dynamic-network settings (IP address, netmask, gateway, and DNS address) over DHCP, ensure that the Flex switches have consistent settings (for example, ensure that the IP addresses are in the same subnet as the CMM).

Important
For each Flex System chassis, ensure that the fabric type of the expansion card in each server in the chassis is compatible with the fabric type of all Flex switches in the same chassis. For example, if Ethernet switches are installed in a chassis, all servers in that chassis must have Ethernet connectivity through the LAN-on-motherboard connector or an Ethernet expansion card. For more information about configuring Flex switches, see Configuring I/O modules in the Flex Systems online documentation.

Procedure

The configuration steps might vary, depending on the type of Flex switches that are installed. For more information about each of the supported Flex switches, see Flex System network switches in the Flex Systems online documentation.

Typically, you must configure the Flex switches in Flex switch bays 1 and 2.

Tip
Flex switch bay 2 is the third module bay when looking at the rear of the chassis.
