<color darkorange>Oct 2023</color>

----
===== Introduction =====

When fitting a Mellanox ConnectX5 or ConnectX6 card to either RX1 (ConnectX5) or CE1 (ConnectX6) we need get obtain a license and put this on the M1 server, before requesting licences we require the serial number of the actual card.
\\ 
\\ 
Use the following procedure to obtain the card serial number:
\\ 
<file>
Use the following Commands:

lspci | grep Mellanox 

sudo lspci -vv -s xx:xx.x | grep " Serial number" 

where xx:xx.x is the first string in the previous command 

Returns (example with one card in the chassis) 

lspci | grep Mellanox 
02:00.0 Ethernet controller: Mellanox Technologies MT2892 Family [ConnectX-6 Dx] 
02:00.1 Ethernet controller: Mellanox Technologies MT2892 Family [ConnectX-6 Dx] 

sudo lspci -vv -s 02:00.0 | grep " Serial number" 
[SN] Serial number: MT2045X09274 

Give this serial number to Gavin Dragonetti and he will supply you with a license file.

when you get the file, rename it to rivermax.lic and put it in this folder on the CE1

/opt/mellanox/rivermax (you may have to create the rivermax folder)

Reboot the Server
