Dell SmartFabric OS10 Installation, Upgrade, and Downgrade Guide

Before you begin

• Accessing the OS10 hshell requires root user privileges. Ensure that you obtain the root user credentials.
• Ensure that you shut down all the ports on the OS10 switch.
• Ensure to save the running configuration before performing a power-cycle.

This firmware update method does not require serial access or a USB port. To update the PCIe firmware from the OS10 hshell:

1. Log in to the switch.
2. Copy the firmware to a known location; for example, /home/admin.

   OS10# system "sudo -i"
   [sudo] password for admin:
   
   root@OS10# cd /home/admin
   
   root@OS10:/home/admin# scp username@host-ip:/filepath/pcieg3fw.bin .
   
   root@OS10:/home/admin# ls
   pcieg3fw.bin
   

3. Enter the OS10 hshell.

   root@OS10:/home/admin# hshell
   Welcome to the NPU Shell
   type ::exit to exit the shell and ::[npu] to change the default npu

5. Enter ::exit to return to the OS10 Linux shell.

   SAI.0> ::exit
