RJ-45 console port

If the DTE has a DB-9 interface, you can connect to the console using an RJ-45 to DB-9 adapter along with the RJ-45 rollover cable.
The following table lists the pin assignments.

Before you install an operating system

After you power-on the system, the S4810-ON uses the U-Boot bootloader and goes through a power-on self-test (POST). POST runs
every time that the switch is initialized and checks hardware components to determine if the switch is fully operational before completing
the boot process. Your system comes with open networking installation environment (ONIE) installed.
During initial setup, the system boots to ONIE Install. ONIE Install boots with ONIE Discovery to the ONIE console (ONIE:).

ONIE Service Discovery

ONIE attempts to locate the installer through a number of discovery methods, as shown. To download and run an installer, the ONIE
Service Discovery feature uses the first successful method found.
1. Passed from the boot loader.
2. Search locally attached storage devices for one of the ONIE default installer filenames (for example, USB).
3. Exact the URLs from DHCPv4.
4. Inexact URLs based on DHCPv4 responses.
5. Query to IPv6 link-local neighbors using HTTP for an installer.
6. TFTP waterfall — from DHCPv4 option 66
If none of the ONIE Service Discovery methods are successful, you can disable is using the onie-discovery-stop command.
You can install an operating system manually from HTTP, FTP, or TFTP using the onie-nos-install <URL> command.
The ONIE Install environment uses DHCP to assign an IP address to the management interface (eth0). If that fails, it uses the default IP
address 192.168.3.10/255.255.255.0.
To display the IP address, use the ifconfig eth0 command.
Example of the ONIE ifconfig eth0 command.
