Technical Product Specification

Intel® Server Boards S4600LH2/T2 TPS
Revision 2.0
155
5. Mellanox* ConnectX-3* Single-Port Infiniband* FD14 Controller
For boards with only one Onboard NIC, the “Onboard NIC2” entries are not present on the screen. The number
of “Port” options which are displayed for each NIC will match the number of ports the Onboard NIC presents.
The IO Modules currently available are:
1. Intel
®
I350 Quad-Port Gigabit Ethernet Module
2. Intel
®
I540 Dual-Port X540 10 Gigabit RJ-45 Module
3. Intel
®
82599 Dual-Port 10 Gigabit SFP+ Module
4. Mellanox* ConnectX-3* Single-Port Infiniband* FD14 Module
For the IO Module entries on the NIC Configuration screen, only entries for modules which are currently
installed will appear, and only ports which exist on those IO Modules will appear.
If an IO Module which had been installed is no longer installed when the system is booted, all NIC
Configuration entries which are specific to that IO Module will be reset to their default values and hidden. If a
different IO Module is installed than had been previously installed, the module-specific settings will still be
returned to defaults, but not hidden. This will not necessarily affect the Option ROM settings, which depend on
the aggregate capabilities of all installed Onboard and IO Module NICs.
For each NIC port which is present on an Onboard NIC or IO Module other than Infiniband* controllers, there
will be a port-specific PXE Boot enabling option and a MAC Address display. Onboard NICs and NIC ports also
have enable/disable options. IO Modules and the ports on them cannot be disabled by BIOS.
Infiniband* controllers which appear as Onboard NICs or as IO Modules have a slightly different format. They
do not have enable/disable options, but they do have a choice of whether to enable loading and executing the
embedded Option ROM for the controller, which will cause it to become bootable. For Infiniband*, both a GUID
and a MAC Address are displayed. The GUID is used for Infiniband* Fabric operations, and the MAC Address
is used when the controller is attached as an Ethernet device.
For non-Infiniband* NICs, there are different OPROMs for different protocols, which are also differentiated by
speed, 1 Gb or 10 Gb. For a given protocol/speed, all Ethernet controllers of the same speed use the same
Option ROM.
PXE – there are two separate PXE Option ROMs, one for 1 Gb NICs and another for 10 Gb NICs. The two are
independent of each other, but each must be the only Option ROM enabled in its speed class. If 1 GbE PXE is
enabled, then the discs OPROM cannot be enabled. If 10 GbE PXE is enabled, then neither discs nor 10 GbE
FCoE may be enabled.
discs – there is only one discs Option ROM for both 1 GbE and 10 GbE NICs. If discs is enabled, then neither
PXE nor FCoE OPROMs may be enabled for the 1 GbE or 10 GbE NICs.
FCoE – there is a 10 GbE FCoE Option ROM that supports the Intel
®
82599 NIC. When it is enabled, the discs
OPROM and the 10 GbE PXE OPROM must be disabled
Note: These Option ROMs are only in support of onboard NICs and installed IO Modules. They do not support
NICs on add-in network cards, even if the NIC on an add-in card is the same type of device as an onboard NIC
or IO Module controller.
Only the Option ROMs for which controller capabilities are present are shown in the screen for selection. For
example, if there are no 10 GbE NICs installed, then the 10 GbE OPROMs will not appear for selection. If
controller capabilities are present, but all controllers with those capabilities are disabled, then the relevant
OPROM options will appear, but will be disabled and grayed out and not changeable.
