What is the recommended way of securely installing a PCIE card on Jetson Orin AGX?

[orgicus]

Hi,

I have a Jetson Orin AGX and a 2x 10Gb Network PCIE card.
I was pleasently surprised the card just worked plug’n’play with no additional driver setup required!

As an initial test I can use it as is, however on the long run this feels insecure and I risk damaging both the card and Jetson.

What is the recommended method of mounting and securing a PCIE card on Jetson Orin AGX ?
(Are there any existing brackets / enclosures ? Would one need to design and manufacture it ?)

Thank you for your time,
George

Hi,

If you are designing a custom base board, then it means some adaptation configurations are needed.
Otherwise, your board may not work fine.

For Orin AGX series, you could refer to below document
https://docs.nvidia.com/jetson/archives/r36.3/DeveloperGuide/HR/JetsonModuleAdaptationAndBringUp/JetsonAgxOrinSeries.html?highlight=universal%20serial%20bus#jetson-agx-orin-platform-adaptation-and-bring-up
(please be aware that above link is for rel-36.3/jetpack6.0)

This document includes below configuration

1. pinmux change & GPIO configuration
2. EEPROM change as most custom boards do not have an EEPROM on it.
3. Kernel porting
4. PCIe configuration
5. USB configuration
6. MGBE configuration
7. RGMII configuration

Thanks!

Hi @carolyuu

Thank you for the swift reply.

I’ve started testing using this card: Intel Dual Port PCIe 10GbE Server/Workstation Ethernet Network Adapter X540T2BLK OEM.

My question is regarding how to physically secure the board so it can’t accidentally move around.
(e.g. on a typical motherboard there’s a notch that locks the board in place so it can’t accidentically be taken out while the computer is powered on).

Would you happen to have any suggestions on how to lock the board so it’s stable ?

Thank you,
George

Just for personal use you may 3d-print something. There is nothing you can buy - the devkit is only meant for laboratory use.

For a product to sell your should have a look at this carrier board:

Forge Carrier Board for NVIDIA® Jetson AGX Orin™ - Connect Tech Inc.

This already has got two 10G Ethernet ports onboard (plus two 1G), and while the Intel X540 only supports 1G and 10G this board also supports 2.5G and 5G Ethernet speeds on both of the 10G ports.
