Hardware Installation

Follow these steps to install Chelsio adapter in your system:
i. Shutdown/power off your system.
ii. Power off all remaining peripherals attached to your system.
iii. Unpack the Chelsio adapter and place it on an anti-static surface.
iv. Remove the system case cover as per the system manufacturer's instructions.
v. Remove the PCI filler plate from the slot where you will install the Ethernet adapter.
vi. For maximum performance, it is highly recommended to install the adapter into a PCIe x8/x16
slot.
All 4-ports of T6425-CR adapter will be functional only if PCIe x8 -> 2x PCIe x4 slot
Note
bifurcation is supported by the system and enabled in BIOS. Otherwise, only 2-ports
will be functional.
vii. Holding the Chelsio adapter by the edges, align the edge connector with the PCI connector
on the motherboard. Apply even pressure on both edges until the card is firmly seated. It may
be necessary to remove the SFP (transceiver) modules prior to inserting the adapter.
viii. Secure the Chelsio adapter with a screw, or other securing mechanism, as described by the
system manufacturer's instructions. Replace the case cover.
ix. After securing the card, ensure that the card is still fully seated in the PCIE x8/x16 slot as
sometimes the process of securing the card causes the card to become unseated.
x. Connect a fiber/twinax cable, multi-mode for short range (SR) optics or single-mode for long
range (LR) optics, to the Ethernet adapter or regular Ethernet cable for the 1Gb Ethernet
adapter.
xi. Power on your system.
xii. Run update-pciids command to download the current version of PCI ID list
xiii. Verify if the adapter was installed successfully by using the lspci command
For Chelsio adapters, the physical functions are currently assigned as:
Physical functions 0 - 3: for the SR-IOV functions of the adapter
