Install Extreme 9920 Software

Before you begin

  • Throughout the installation process, a serial console must be connected to the device.
  • The out-of-band management Ethernet interface must be connected if you are using a remote NFS share, HTTP, FTP, or TFTP:
    • Availability of a DHCP server on the LAN for this Ethernet interface might enable you to skip the need to manually configure the ONIE to connect to one of the network-based methods of transferring the software.
    • If a DHCP server is not available, you need the default gateway, network mask, and an IP address that is not in use on the network to which the Ethernet interface is connected.

About this task

You can download the Extreme 9920 software image from a remote server using any of the following methods:

  • Prepared USB 3.0 device
  • Remote NFS share
  • HTTP
  • FTP
  • TFTP
Perform the following steps from the serial console.

Procedure

  1. Access the ONIE Recovery Shell.
    1. Reboot the device using the CLI or power-cycle.
    2. When the BIOS splash screen is displayed, use the Down Arrow key to access the GRUB boot menu and stop the boot timer.
    3. Select ONIE from the first menu, and press the Down Arrow key to stop the boot timer.
    4. Select ONIE: Rescue, and press Enter when prompted.
      The ONIE shell opens.
    You can use ONIE for recovering or upgrading the device.
  2. Perform one of the following:
    • If a DHCP server is running on the network, proceed to the next step.
    • If using remote server to download the firmware, go to step 5.
  3. Check connectivity to the server hosting the software.
    1. Ping the remote server from which you intend to download the software.
    2. If the ping fails, run the following commands to gather information on the connection state.
      ip addr
      ip route show
      ifconfig
      If there are any errors, perform step 4 to resolve them. Otherwise, proceed to step 5.
  4. Configure static networking on eth0 for ONIE.
    1. Add the IP address to the eth0 interface.
      ONIE:/ #ip addr add <ip-addr/mask> dev eth0
    2. Configure the default gateway.
      ONIE:/ #ip route add default via <gateway-ip-addr> dev eth0
  5. Download and install the Extreme 9920 software firmware using one of the following remote server methods:
    A checksum validation is done before installing the firmware.
  6. Activate the firmware using Activate gRPCs.
  7. Verify if the installation is successful using Verify gRPCs.
