Identifying The Card In Your System - Nvidia MCX651105A-EDAT User Manual

6. To remove a cable, disengage the locks and slowly pull the connector away from the port receptacle. LED indicator will turn off when the cable is
unseated.

Identifying the Card in Your System

On Linux
Get the device location on the PCI bus by running lspci and locating lines with the string "Mellanox Technologies":
ConnectX-6 Card Configuration
Single-port Socket Direct Card (2x
PCIe x16)
Dual-port Socket Direct Card (2x PCIe
x16)
Single-port PCIe x8/x16 Card
lspci Command Output Example
[root@mftqa-009 ~]# lspci |grep mellanox -i
a3:00.0 Infiniband controller: Mellanox Technologies MT28908 Family [ConnectX-6]
e3:00.0 Infiniband controller: Mellanox Technologies MT28908 Family [ConnectX-6]
[root@mftqa-009 ~]# lspci |grep mellanox -i
05:00.0 Infiniband controller: Mellanox Technologies MT28908A0 Family [ConnectX-6]
05:00.1 Infiniband controller: Mellanox Technologies MT28908A0 Family [ConnectX-6]
82:00.0 Infiniband controller: Mellanox Technologies MT28908A0 Family [ConnectX-6]
82:00.1 Infiniband controller: Mellanox Technologies MT28908A0 Family [ConnectX-6]
In the output example above, the first
two rows indicate that one card is installed in a PCI slot with PCI Bus address 05 (hexadecimal), PCI Device number 00 and PCI Function
number 0 and 1. The other card is installed in a PCI slot with PCI Bus address 82 (hexa-decimal), PCI Device number 00 and PCI Function number 0 a
nd 1.
Since the two PCIe cards are installed in two PCIe slots, each card
gets a unique PCI Bus and Device number. Each of the PCIe x16 busses sees two network ports; in effect, the two
physical ports of the ConnectX-6 Socket Direct adapter are viewed as four net devices by the system.
