    Connect the two supplied power cords to the power supplies on the back of the appliance, and then plug the cords into a power outlet. If the appliance does not power on automatically, press the power button on the front of the appliance.

Configure an IP address

DHCP is enabled by default on the ExtraHop appliance. When you power on the appliance, interface 1 attempts to acquire an IP address through DHCP. If successful, the IP address appears on the home screen of the LCD. If an IP address has not been configured, the LCD displays No IP.

If your network does not support DHCP, you can configure a static IP address through the LCD menu on the front panel or through the command-line interface (CLI).

Configure an IP address through the CLI

You can access the CLI by connecting a USB keyboard and SVGA monitor to the appliance or through an RS-232 serial cable and a terminal-emulator program. The terminal emulator must be set to 115200 bps with 8 data bits, no parity, 1 stop bit (8N1), and hardware flow control should be disabled.

  1. Establish a connection to the ExtraHop appliance.
  2. At the login prompt, type shell and then press ENTER.
  3. At the password prompt, type the service tag number found on the pullout tab on the front of the appliance, and then press ENTER.
  4. To configure the static IP address, run the following commands:
    1. Enable privileged commands: 
      enable
    2. At the password prompt, type the service tag number, and then press ENTER.
    3. Enter configuration mode: 
      configure
    4. Enter the interface configuration mode: 
      interface
    5. Run the ip command and specify the IP address and DNS settings in the following format: ip ipaddr <ip_address> <netmask> <gateway> <dns_server>
      For example:
      ip ipaddr 10.10.2.14 255.255.0.0 10.10.1.253 10.10.1.254
    6. Leave the interface configuration section: 
      exit
    7. Save the running config file: 
      running_config save
    8. Type y and then press ENTER.
