Install a physical sensor

Before you can use your Nozomi Networks physical sensor in your network, you must install it.

If you purchased a physical sensor from Nozomi Networks, the appropriate release of the Nozomi Networks Operating System (N2OS) is already installed on it. If your organization uses a different release of the N2OS, then see Software updates and rollbacks in the Maintenance Guide to upgrade the release.
  1. Follow the procedure described in the Quick Start Guide that you received with the sensor.
    Note: The status of your sensor should now:
    • Be installed in a rack
    • Be powered on
    • Have its monitoring ports connected to the relevant network switches
  2. Connect the appropriate null-modem serial cable to the sensor's serial console.

  3. Open a terminal emulator.
    Note: Use the appropriate terminal emulator for your operating system (OS):
    • On Windows, Hyper Terminal or Putty
    • On macOS or other *nix platforms, cu or Minicom
  4. Connect and set the speed to 9600 bauds with no parity bit set.
  5. Optional: Connect with secure shell (SSH). Use the default network settings:
    IP address: 192.168.1.254
    Netmask: 255.255.255.0
    GW: 192.168.1.1
    A login prompt for the sensor shows.
  6. Do the Basic configuration.
