Population guidelines
High-speed fabric switches can be installed in bays 3 and 4. Populating the high-speed fabric switch bays
depends on the configuration of the installed servers in the chassis. This configuration includes:
• Mezzanine cards
◦ The number of mezzanine cards installed in the servers.
◦ The type of mezzanine card installed in the servers (EDR or OPA).
◦ How the mezzanine card is cabled.
• Processors
◦ The number of processors installed in the servers.
◦ The type of processor installed in the servers (standard socket or -F processor).
◦ How the -F processor is cabled.
Use the following table to determine bay population requirements.
